SEC. 8. The whole term of service which forms the basis for deter- mining the amount of the annuity provided in section 5 of this Act shall be computed from the date of original employment as a teacher, other than temporary, in the public schools of the District of Columbia, plus any service credit that may be allowed under the provisions of this section. In computing the length of service of retiring teachers credit may be given, year for year, for (a) public-school service or its equivalent outside the District of Columbia but not to exceed ten ears; (b) continuous temporary service in the public schools of the District of Columbia immediately prior to probationary appointment; (c) service in the government of the District of Columbia or the Government of the United States allowable under the Civil Service Act of 1920, as amended; (d) periods of honorable service in the Army, Navy, Marine Corps, or Coast Guard of the United States in time of war; (e) all educational leaves of absence with part pay authorized by the Board of Education in accordance with the Act of June 12, 1940 (54 Stat. 349); and the first ten-year period to begin on the date of the first probationary appointment as a teacher in the public schools of the District of Columbia: Provided,however, That that portion of the annuity which results from credit for service allowable under (a) and (c) of this section shall be reduced by the amount of any annuity which the retired teacher is entitled to receive under any Federal, State, or municipal retirement or pension system in respect to such service, except that such portion of the annuity after reduction shall not be less than the annuity purchasable with the deposit which the teacher is required to make under the provisions of this section in order to obtain credit for such service: Provided further, That no credit for service prescribed in this section, with the exception of periods of honorable service in the Army, Navy, Marine Corps, or Coast Guard of the United States in time of war and all educational leaves of absence with part pay authorized by the Board of Education in accordance with the Act of June 12, 1940 (54 Stat. 349), shall be given to any teacher entering the said public schools after June 30, 1926, until he shall have deposited to the credit of the teachers' retirement and annuity fund of the District of Columbia a sum equal to the accumulated contributions and interest which he would have had credited to his individual account if such service had been rendered on active duty in the public schools of the District of Columbia, said contributions to be based on the average annual salary of the class to which the teacher is appointed: Providedfurther, That all contributions to the retirement fund made by any teacher on educational leave with part pay shall be determined in accordance with the provisions of section 1 of this Act, but otherwise no pro- vision of this Act shall be interpreted to deprive any teacher employed by the Board of Education of any rights or benefits allowable under the Act of June 12, 1940 (54 Stat. 349): Provided further, That if the teacher so elects, he may deposit the required sum in the fund in any number of monthly installments not exceeding fifty with interest at 3 per centum per annum compounded annually, upon making claim with the Auditor, District of Columbia, within one year of the effec- tive date of this Act, or within one year after the original probational appointment or reinstatement in the school service, or within two years 879 Calculation of ap- propriation.
