                           TO BE HELD AUGUST 29, 2002

                                 PROXY STATEMENT

                             -----------------------

                             SOLICITATION OF PROXIES

      The accompanying proxy is solicited by the Board of Directors of Quality
Systems, Inc. (the "Company") for use at the Company's Annual Meeting of
Shareholders to be held at The Center Club, 650 Town Center Drive, Costa Mesa,
California on Thursday, August 29, 2002 at 1:00 P.M. Pacific Time, and at any
and all adjournments thereof. All shares represented by each properly executed
and unrevoked proxy received in advance of the Annual Meeting will be voted in
the manner specified therein.

      Any shareholder has the power to revoke his or her proxy at any time
before it is voted. A proxy may be revoked by delivering a written notice of
revocation to the Secretary of the Company, by submitting prior to or at the
Annual Meeting a later dated proxy executed by the person executing the prior
proxy, or by attendance at the Annual Meeting and voting in person by the person
executing the proxy.

      This proxy statement, the accompanying proxy card and the Company's Annual
Report are being mailed to the Company's shareholders on or about July 24, 2002.
The cost of soliciting proxies will be borne by the Company. The solicitation
will be made by mail and expenses will include reimbursement paid to brokerage
firms and others for their expenses in forwarding solicitation material
regarding the Annual Meeting to beneficial owners of the Company's Common Stock.
Further solicitation of proxies may be made by telephone or oral communications
with some shareholders. Such further solicitations would be made by the
Company's regular employees who will not receive additional compensation for the
solicitation.

                      OUTSTANDING SHARES AND VOTING RIGHTS

      Only holders of record of the 6,111,506 shares of the Company's Common
Stock outstanding at the close of business on July 24, 2002, are entitled to
notice of and to vote at the Annual Meeting or any adjournment thereof. A
majority of the shares, represented in person or by proxy, will constitute a
quorum for the transaction of business. All proxies delivered to the Company
will be counted in determining the presence of a quorum, including those
providing for abstention or withholding of authority and those delivered by
brokers voting without beneficial owner instruction and exercising a non-vote on
certain matters. The seven nominees for director receiving the highest number of
affirmative votes will be elected; votes withheld and votes against a nominee
have no practical effect. In matters other than election of directors, assuming
that a quorum is present, the affirmative votes of a majority of the shares


                                      -1-


represented and voting at a meeting (which shares voting affirmatively also
constitute at least a majority of the required quorum) is required for approval;
in such matters, abstentions and broker non-votes are not counted. Each
shareholder will be entitled to one vote, in person or by proxy, for each share
of Common Stock held of record on the record date, except that all shareholders
have cumulative voting rights and in the event any shareholder gives notice at
the Annual Meeting, prior to the voting, of an intention to cumulate his or her
votes in the election of directors, then all shareholders entitled to vote at
the Annual Meeting may cumulate their votes in the election of directors.
Cumulative voting means that a shareholder has the right to give any one
candidate whose name has been properly placed in nomination prior to the voting
a number of votes equal to the number of directors to be elected multiplied by
the number of shares such shareholder would otherwise be entitled to vote, or to
distribute such votes on the same principle among as many nominees (up to the
number of persons to be elected) as the shareholder may wish. The proxy being
solicited by the Board of Directors confers discretionary authority to cumulate
votes.

                              ELECTION OF DIRECTORS

                                (Proposal No. 1)

      Directors are elected at each Annual Meeting of Shareholders and hold
office until their respective successors are duly elected and qualified. The
full Board of Directors consists of seven directors. Certain information with
respect to the seven nominees who will be presented at the Annual Meeting by the
Board of Directors for election as directors is set forth below. Although it is
anticipated that each nominee will be available to serve as a director, should
any nominee become unavailable to serve, the proxies will be voted for such
other person as may be designated by the Company's Board of Directors.

      Unless the authority to vote for directors has been withheld in the proxy,
the persons named in the enclosed proxy intend to vote at the Annual Meeting for
the election of the nominees presented below. However, discretionary authority
to cumulate votes represented by proxies and to cast such votes for any or all
of the nominees named below is solicited by the Board of Directors because, in
the event nominations are made in opposition to the nominees of the Board of
Directors, it is the intention of the persons named in the enclosed proxy to
cumulate votes represented by proxies in accordance with their best judgment for
individual nominees in order to assure the election of as many of the nominees
to the Board of Directors as possible.

      In the election of directors, assuming a quorum is present, the seven
nominees receiving the highest number of votes cast at the meeting will be
elected directors. As a result, proxies voted to "Withhold Authority" and broker
non-votes will have no practical effect upon the election of directors, although
proxies specifying "Withhold Authority" will be counted for purposes of
determining whether a quorum is present, as will proxies delivered by brokers
voting without beneficial owner instruction and exercising a non-vote on certain
matters.

      YOUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" ELECTION OF EACH OF
THE NOMINEES NAMED BELOW.

                                LEGAL PROCEEDINGS

      On April 22, 1997, a purported class action entitled JOHN P. CAVENY v.
QUALITY SYSTEMS, INC., ET AL. was filed in the Superior Court of the State of
California for the County of Orange, in which Mr. Caveny, on behalf of himself
and all others who purchased the Company's Common Stock between June 26, 1995
and July 3, 1996, alleges that the Company, and Sheldon Razin, Robert J. Beck,
Gregory S. Flynn, Abe C. LaLande, Donn Neufeld, Irma G. Carmona, John A. Bowers,
Graeme H. Frehner, and Gordon L. Setran (all of the foregoing individuals were
either officers, directors or both during the period from June 26, 1995 through
July 3, 1996), as well as other defendants not affiliated with the Company,
violated California Corporations Code Sections 25400 and 25500, California Civil
Code Sections 1709 and 1710, and California Business and Professions Code
Sections 17200 et. seq., by issuing positive statements about the Company that
allegedly were knowingly false, in part, in order to assist the Company and the
individual defendants in selling Common Stock at an inflated price in the
Company's March 5, 1996 public offering and at other points during the class
period. The complaint seeks compensatory and punitive damages in unspecified
amounts, disgorgement, declaratory and injunctive relief, and attorneys' fees.

      The Company and the other named defendants successfully demurred to the
plaintiffs' claim under California Civil Code Sections 1709 and 1710, and that
claim, which served as the only basis for plaintiffs' request for punitive
damages, has been dismissed from both actions.


                                      -5-


      On January 25, 1999, the court denied plaintiffs' motion to certify the
class representative and class legal counsel. Plaintiffs appealed that decision
as to class legal counsel. On February 25, 2000, the Fourth District Court of
Appeals affirmed the order disqualifying the class legal counsel. On May 9,
2000, the Court of Appeals issued its Remittur certifying its decision as final.

      In May 2000, plaintiffs associated in additional class legal counsel, and
moved for approval by the court. Upon defendants' objection, the court on August
17, 2000, denied plaintiffs' motion, and ordered plaintiffs to retain new class
counsel.

      At the end of November 2000, the plaintiffs retained new class counsel who
substituted in for plaintiffs' previous class counsel. The Company and the other
named defendants did not oppose plaintiffs' motion for approval of the new class
counsel. On January 24, 2001, the court granted the motion to certify class
legal counsel.

      On March 27, 2001, the court approved a notice of class certification to
be mailed to shareholders who are potential class members. Between April 9, 2001
and May 9, 2001, class notice was mailed to potential class members.

      Merits-related discovery in the action, which had been stayed pending the
appointment of class counsel, is now ongoing. In March 2002, defendant Graeme H.
Frehner and certain other defendants not affiliated with the Company were
dismissed from the action with prejudice by stipulated order.

      The parties are scheduled to appear in court for the next status
conference on October 22, 2002. Trial in the action has been set for March 24,
2003.

      In Management's opinion the outcome of this case is uncertain, and
therefore no accrual has been made to the financial statements.

      On May 14, 1997, a second purported class action entitled WENDY WOO v.
QUALITY SYSTEMS, INC., ET AL. was filed in the same court, essentially repeating
the allegations in the Caveny lawsuit and seeking identical relief. This action
has for all purposes been consolidated with the Caveny action.

      The Company is a party to various other legal proceedings incidental to
its business, none of which are considered by the Company to be material.

                 BOARD OF DIRECTORS MEETINGS AND RELATED MATTERS

      During the fiscal year ended March 31, 2002, the Board of Directors held
five meetings and there were two actions by unanimous written consent. No
director, except Mohammed Tawfick El-Bardai, attended less than 75% of the
aggregate of all meetings of the Board of Directors and all meetings of
committees of the Board of Directors upon which he served.

      The By-laws of the corporation require that at least three-quarters of the
members of the board of directors shall be independent. For purposes of any
action by the board, at least one-half of the directors present and eligible to
vote must be independent. An independent director means a person who:

      (a)   has never been an employee of the Company or any of its
            subsidiaries.

      (b)   provides no services to the Company or to the Chief Executive
            Officer or senior management of the Company as an advisor,
            consultant or otherwise.


                                      -6-


      (c)   is not employed by an entity which provides services to the Company
            or to the Chief Executive Officer or senior management of the
            Company as an adviser, consultant or otherwise.

      (d)   is not affiliated with a significant customer or supplier of the
            Company ("significant" means more than 1% of annual sales).

      (e)   has not had, during the past two years, any interest in any
            significant transaction, or any business or financial relationship,
            with the Company or an affiliate of the Company (other than service
            as a director) for which the Company has been required to make
            disclosure under Regulation S-K of the Securities and Exchange
            Commission.

      (f)   is not a relative of an executive officer or director of the
            Company.

      (g)   receives no compensation from the Company other than director's
            fees.

      (h)   does not personally receive and is not an employee, director, or
            trustee of a foundation, university, or other institution that
            receives grants or endowments from the Company that are material to
            the Company or to either the recipient and/or the foundation,
            university or institution.

      (i)   is not employed by an entity of which (i) an executive officer of
            the Company serves as a director or trustee, or (ii) a director of
            the Company serves in a senior executive capacity.

      The Board of Directors has an Audit Committee which consists of Messrs.
Hussein, Hanson, Meyer and Zikry. The Audit Committee is comprised entirely of
non-employee, independent directors and operates under a written charter adopted
by the Board of Directors. The duties of the Audit Committee include meeting
with the independent public accountants of the Company to review the scope of
the annual audit and to review the quarterly and annual financial statements of
the Company before the statements are released to the Company's shareholders.
The Audit Committee also evaluates the independent public accountants'
performance and makes recommendations to the Board of Directors as to whether
the independent public accounting firm should be retained by the Company for the
ensuing fiscal year. In addition, the Audit Committee reviews the Company's
internal accounting and financial controls and reporting systems practices.
During the fiscal year ended March 31, 2002, the Audit Committee held 14
meetings.

      The Board of Directors has a Nominating Committee which consists of
Messrs. Hussein, Meyer, Small and El-Bardai. The Nominating Committee is
responsible for identifying, recommending and nominating candidates to the Board
of Directors and is composed entirely of independent directors. The Nominating
Committee will consider candidate nominees for election as director who are
recommended by shareholders. Recommendations should be sent to the Secretary of
the Company and should include the candidate's name and qualifications and a
statement from the candidate that he or she consents to being named in the Proxy
Statement and will serve as a director if elected. In order for any candidate to
be considered by the Nominating Committee and, if nominated, to be included in
the Proxy Statement, such recommendation must be received by the Secretary on or
before the March 31st preceding the annual meeting at which directors will be
elected by the shareholders. During the fiscal year ended March 31, 2002 the
Nominating Committee held one meeting.

      The Board of Directors has a Compensation Committee which consists of
Messrs. Hussein, Zikry, Meyer and Small. The Compensation Committee is composed
entirely of independent directors, and is responsible for (i) ensuring that
senior management will be accountable to the Board through the effective
application of compensation policies and (ii) monitoring the effectiveness of
both senior management and the Board (including committees thereof). The
Compensation Committee establishes compensation policies applicable to the
Company's executive officers. During the fiscal year ended March 31, 2002, the
Compensation Committee held four meetings.


                                      -7-


      The Board of Directors has a Transaction Committee which consists of
Messrs. Hussein, Hanson, Meyer and Small. The Transaction Committee is
responsible for considering and making recommendations to the Company's Board of
Directors with respect to all proposals involving (i) a change in control of the
Company or (ii) the purchase or sale of assets constituting more than 10% of the
Company's total assets. The Transaction Committee has four members, all of whom
are current members of the Company's Board of Directors and all of whom must be
independent directors. During the fiscal year ended March 31, 2002, the
Transaction Committee held seven meetings.

      If at any time the Chairman of the Board shall be an executive officer of
the Company, or for any other reason shall not be an independent director, a
non-executive Lead Director ("Lead Director") shall be selected by the
independent directors. The Lead Director shall be one of the independent
directors, shall be a member of the Audit Committee and of the Executive
Committee, if there is such a committee, and shall be responsible for
coordinating the activities of the independent directors. He shall assist the
Board in assuring compliance with the Company's corporate governance procedures
and policies, and shall coordinate, develop the agenda for, and moderate
executive sessions of the Board's independent directors. Such executive sessions
shall be held immediately following each regular meeting of the Board, and may
be held at other times as designated by the Lead Director. The Lead Director
shall approve, in consultation with the other Independent Directors, the
retention of consultants who report directly to the Board. If at any time the
Chairman of the Board is one of the independent directors, then he or she shall
perform the duties of the Lead Director. Ahmed Hussein served as Lead Director
during the fiscal year ended March 31, 2002.

      The independent directors have organized an Executive Committee, which
consists of all of the independent directors, Messrs. El-Bardai, Hanson,
Hussein, Meyer, Small, and Zikry. During the fiscal year ended March 31, 2002,
the Executive Committee held four meetings. The Executive Committee handles
certain matters as may be directed by the Board of Directors from time to time.

      Directors of the Company who are also employees of the Company are not
compensated for their services as directors or committee members. Directors of
the Company who are not also employees receive a fee of $2,500 per year for
serving on the Board of Directors. Directors who serve on a committee of the
Board of Directors receive an additional annual fee of $1,000 and a fee of $250
for each committee meeting attended, together with reasonable expenses of
attendance at committee meetings.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

      No director or executive officer of the Company serves as an officer,
director or member of a compensation committee of any other entity for which an
executive officer or director thereof is also a member of the Company's Board of
Directors.

                       COMPENSATION OF EXECUTIVE OFFICERS

      The following table sets forth certain compensation information for the
three fiscal years ended March 31, 2002, 2001 and 2000, respectively, by the
Chief Executive Officer and the other highest paid executive officers of the
Company (up to four) serving as such at the end of the 2002 fiscal year whose
aggregate total annual salary and bonus for such year exceeded $100,000 (the
"Named Executive Officers").

plus a lump sum payment equal to six months base compensation; (ii) any
performance bonus earned but not paid; and (iii) immediate vesting of all

other transfer of 35% of more of the total assets of the Company, the merger or
consolidation of the Company with another company with the effect that the
shareholders of the Company immediately prior to the merger hold less than 51%

company; the replacement of a majority of the Company's Directors without the
approval of the Board of Directors; the purchase of 25% or more of the combined

the purchase of securities by Ahmed Hussein or Sheldon Razin of shares owned by
either Sheldon Razin or Ahmed Hussein. The Agreement also grants immediate
vesting of all unvested options should a change of control occur whether or not
Mr. Silverman's employment is terminated.

      For options other than those discussed above, the Board of Directors, as
the administrator of the Company's 1989 Stock Option Plan and 1998 Stock Option
Plan, has the discretion to accelerate any outstanding options held by the Named
Executive Officers and employees in the event of an acquisition of the Company
by a merger or asset sale in which the outstanding options under each such plan
are not to be assumed by the successor corporation or substituted with options
to purchase shares of such corporation.

           REPORT OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION

      The Company applies a consistent philosophy to compensation for all
employees, including senior management. This philosophy is based on the premise
that the achievements of the Company result from the coordinated efforts of all
individuals working toward common objectives. The Company strives to achieve
those objectives through teamwork that is focused on meeting the expectations of
customers and shareholders.

                             Compensation Philosophy

      The goals of the compensation program are to align compensation with
business objectives and performance, and to enable the Company to attract,
retain and reward executive officers who contribute to the long-term success of
the Company. The Company's compensation program for executive officers is based
on the same four principles applicable to compensation decisions for all
employees of the Company:

      o     The Company pays competitively. The Company is committed to
            providing a pay program that helps attract and retain highly
            qualified people in the industry. To ensure that pay is competitive,
            the Company regularly compares its pay practices with those of other
            leading companies and sets its pay parameters based on this review.

      o     The Company pays for relative sustained performance. Executive
            officers are rewarded based upon corporate performance, business
            unit performance and individual performance. Corporate performance
            and business unit performance are evaluated by the Board of


                                      -11-


            Directors (in the case of the Chief Executive Officer) and by the
            Chief Executive Officer (in the case of all other executive
            officers) by reviewing the extent to which strategic and business
            plan goals are met, including such factors as operating profit,
            performance relative to competitors and timely new product
            introductions. Individual performance is evaluated by quantitatively
            and qualitatively reviewing organizational and management
            development progress against set objectives and the degree to which
            teamwork and Company values are fostered.

      o     The Company strives for fairness in the administration of pay and to
            achieve a balance of the compensation paid to a particular
            individual with the compensation paid to other executives both
            inside the Company and at comparable companies.

      o     The Company believes that employees should understand the
            performance evaluation and pay administration process. The process
            of assessing performance is as follows:

            1.    At the beginning of the performance cycle, the Chief Executive
                  Officer or other evaluating manager sets objectives and key
                  goals.

            2.    The evaluating manager gives the employee ongoing feedback on
                  performance.

            3.    At the end of the performance cycle, the manager objectively
                  and subjectively evaluates the accomplishment of
                  objectives/key goals.

            4.    The manager compares the results to the results of peers
                  within the Company.

            5.    The evaluating manager communicates the comparative results to
                  the employee.

            6.    The comparative result affects decisions on salary and, if
                  applicable, bonus and, if applicable, stock options.

                              Compensation Vehicles

      The Company has historically used a compensation program that consists of
cash and equity based compensation.

      The vehicles are:

      o     Salary. The Company sets base salary for its employees by reviewing
            the base salary for competitive positions in the market in order to
            attract, retain, and motivate highly talented individuals at all
            levels in the organization.

      o     Bonus. The Company utilizes incentive compensation plans for
            selected employees to reward achievement of key objectives and
            goals.

      o     Stock Option Program. The purpose of this program is to provide
            additional incentives to selected employees to work to maximize
            shareholder value. All stock option grants are made by the Board of
            Directors. Stock options generally are granted with an exercise
            price equal to the fair market value of the underlying Common Stock
            on the date of grant and vest in equal annual installments over a
            four-year period.

                             AUDIT COMMITTEE REPORT

      The Audit Committee reports to and acts on behalf of the Board of
Directors in providing oversight to the financial management, independent
auditors, and financial reporting procedures of the Company. The Company's
management is responsible for preparing the Company's financial statements and
the independent auditors are responsible for auditing those statements. In this
context, the Audit Committee has reviewed and discussed the audited financial
statements contained in the 2002 Annual Report on Form 10-K with management and
the independent auditors.

      The Audit Committee has discussed with the independent auditors the
matters required to be discussed by the Statement on Auditing Standards No. 61
("Communication with Audit Committees"), as amended. The Audit Committee has
received the written disclosures and the letter from the independent auditors
required by Independence Standards Board Standard No. 1 (Independence
Discussions with Audit Committees), as amended, and has discussed with the
independent auditors their independence. In concluding that the auditors are
independent, the Committee considered, among other factors, whether the
non-audit services provided by Grant Thornton, LLP were compatible with
maintaining their independence.

      In reliance on the reviews and discussions referred to above, the Audit
Committee recommended to the Board of Directors that the audited financial
statements be included in the Company's Annual Report on Form 10-K for the year
ended March 31, 2002, for filing with the Securities and Exchange Commission.

      The Audit Committee has recommended the appointment of Grant Thornton, LLP
to serve as the Company's independent auditors for the year ended March 31,
2003, subject to shareholder ratification.

                                 AUDIT COMMITTEE

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Under Section 16(a) of the Securities Exchange Act of 1934, as amended,
the directors and officers of the Company and any person who owns more than ten
percent of the Company's Common Stock are required to report their initial
ownership of the Company's Common Stock and any subsequent changes in that
ownership to the Securities and Exchange Commission ("SEC") and the NASDAQ
National Market. Officers, directors and greater than 10% shareholders are
required by SEC regulations to furnish the Company with copies of all forms they
file in accordance with Section 16(a).


                                      -13-


      Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons that no Forms 5 were
required for those persons, the Company believes that, during the fiscal year
ended March 31, 2002, its officers, directors and greater than 10% shareholders
complied with all filing requirements applicable to such persons.

                        FIVE-YEAR PERFORMANCE COMPARISON

      The following graph compares the cumulative total returns of the Company's
Common Stock, the Total Return Index for The NASDAQ Stock Market, and the NASDAQ

                 RATIFICATION OF INDEPENDENT PUBLIC ACCOUNTANTS

                                (Proposal No. 2)

      The Board of Directors has appointed the firm of Grant Thornton, LLP
("Grant Thornton") as its independent public accountants for the fiscal year
ended March 31, 2003, subject to ratification by the holders of a majority of
the shares represented either in person or proxy at the Annual Meeting. The
Company's former independent public accountants were Deloitte & Touche, LLP
("Deloitte & Touche"). In the event that the shareholders do not ratify the
selection of Grant Thornton as the Company's independent public accountants, the
selection of another independent public accounting firm will be considered by
the Board of Directors.

      Representatives of Grant Thornton are expected to attend the Annual
Meeting and will be available to respond to appropriate questions. The
representatives of Grant Thornton also will have the opportunity to make a
formal statement, if they so desire.


                                      -14-


      On July 5, 2001, the Company dismissed Deloitte & Touche as its
independent accountant. The reports of Deloitte & Touche on the Company's
financial statements for the fiscal years ended March 31, 2000 and 2001
contained no adverse opinion or disclaimer of opinion and were not qualified or
modified as to uncertainty, audit scope or accounting principles.

      The Audit Committee's decision to change accountants was approved by the
Company's Board of Directors. In connection with its audits for the fiscal years
ended March 31, 2000 and 2001, and through July 5, 2001, there were no
disagreements with Deloitte & Touche on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedure, which
disagreements if not resolved to the satisfaction of Deloitte & Touche would
have caused them to make reference thereto in their report on the financial
statements for such years. During the fiscal years ended March 31, 2000 and
2001, and through July 5, 2001, there were no reportable events (as defined in
Regulation S-K Item 304(a)(1)(v)). Deloitte & Touche furnished the Company with
a letter addressed to the SEC stating it agrees with the above statements. The
Board of Directors approved the engagement of Grant Thornton as its new
independent accountant for the fiscal year ending March 31, 2002 to replace
Deloitte & Touche. During the fiscal years ended March 31, 2000 and 2001, and
through July 5, 2001, the Company had not consulted with Grant Thornton
regarding either (i) the application of accounting principles to a specified
transaction, either completed or proposed; or the type of audit opinion that
might be rendered on the Company's financial statements; or (ii) any matter that
was either the subject of a disagreement, as that term is defined in Item
304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of
Regulation S-K, or a reportable event, as that term is defined in Item
304(a)(1)(v) of Regulation S-K. The Company authorized Deloitte & Touche to
respond fully to any inquiries from Grant Thornton relating to its engagement as
Company's independent accountant.
