Section 31-F. Participation by the Henry Viscardi school

a. The Henry
  Viscardi school may, by resolution adopted by its board of trustees  and
  approved  by  the  comptroller,  elect  to participate in the retirement
  system. Acceptance of its employees for  membership  in  the  retirement
  system  shall  be optional with the comptroller, who shall determine the
  amounts of contribution payable by  such  employer  and  its  employees,
  shall  resolve  questions  of credit for prior service, and shall in all
  other respects  assure  that  such  employees  share  the  same  rights,
  obligations and benefits as other members of the retirement system.
    b.  The officers and employees of such employer shall be credited with
  such periods of prior service as shall be certified by such employer for
  service rendered to it, or the state, or in any other capacity  approved
  by  such  employer  and the comptroller. Service for such employer after
  the date on which it commences to participate in the  retirement  system
  shall  be  considered  as member service. An officer or employee of such
  employer who, as of the date he or she is so approved for membership  in
  the  retirement  system, is already a member thereof, shall not have his
  or her total credit reduced  by  such  approval.  Any  reserve  held  on
  account of any such officer or employee in the pension accumulation fund
  shall  be  used as an offset against the deficiency contribution payable
  thereafter by such employer on account of such officer or  employee  for
  any prior service credit and any such previous credit.
    c.  Notwithstanding  the  election  by  the  Henry  Viscardi School to
  participate in the retirement system, employees of  such  employer,  who
  are  employed  by  the  employer  prior  to  the  effective date of this
  section, shall have the option to continue participation in the employer
  sponsored retirement plan. Provided, however, an employee, who exercises
  the  option  to  continue  participation  in  the   employer   sponsored
  retirement  plan, shall not be entitled to be a member of the retirement
  system. Such election shall be irrevocable.
