Graduate credit hours beyond thirty which were earned prior to obtaining a master’s degree may be applied in computing such sixty credit hours.” 80 Stat. 1598 (3) Section 4 (D.C. Code, sec. 31–1521) is amended to read as follows: “Sec. 4. Any employee of the Board of Education in group C of a salary class in the salary schedule in section 1 of this Act who possesses a doctor’s degree, and any employee of the Board of Education in group C of salary class 15 of such salary schedule who possesses a master’s degree plus sixty credit hours, shall be transferred in accordance with section 10(a) to group D of such salary class.” (4) Section 5 (D.C. Code, sec. 31–1522) is amended by adding the following new subsections: “(c) The Board of Education, with the concurrence of the Board of Commissioners of the District of Columbia, is authorized to establish a position which shall be designated ‘teacher-aide (noninstructional)’. Such positions shall be classified, in accordance with sections 5102 and 5106 of title 5, United States Code, at a grade not higher than GS–4, and shall be compensated in accordance with the General Schedule in section 5333(a) of title 5, United States Code. The minimum qualification for appointment to such position shall be successful completion of at least sixty semester hours at an accredited junior college, college, or university. A person appointed to such position shall be a noninstructional employee, and his primary duty shall be to assist the instructional staff in tasks related to instruction. The total of the number of teacher-aides (noninstructional) appointed under this Act and the number of persons appointed under any other Act to perform in the public school system of the District of Columbia the same duties as teacher-aides (noninstructional) shall at no time exceed 5 per centum of the number of classroom teachers in salary class 15. “(d) The initial assignment of each position of school principal in the public school system of the District of Columbia to one of the four principal levels within salary class 6 of the salary schedule in section 1 of this Act shall be made in accordance with the following provisions: “(1) Within 60 days following the date of enactment of this subsection, the Board of Education, with the cooperation of the Board of Commissioners of the District of Columbia, shall assign each position of school principal to one of the four principal levels within salary class 6 of the salary schedule in section 1. Such assignment shall be made on the basis of an evaluation by the Board of Education, with the cooperation of the Commissioners of the District of Columbia, of the duties and responsibilities of each position of school principal in the school administered by the person holding such position. Such evaluation shall be based on (A) such workload factors as (i) the academic program, (ii) the number of teachers, nonteaching personnel, and other professional and nonprofessional personnel supervised, (iii) school enrollment, (iv) cocurricular activities, (v) extracurricular activities, and (vi) community activities; and (B) such other factors as the Board of Education deems appropriate. The initial assignment of a position of school principal to a principal level within salary class 6 shall be effective on the effective date of this subsection. “(2) In the case of a person holding the position of school principal on the effective, date of this subsection, the initial assignment of the position held by such person to one of the four principal levels within salary class 6 shall not (A) affect the group and service step occupied by such person, or (B) for the period during which such person holds such position, reduce his rate of compensation below the rate of compensation to which he was entitled immediately prior to such effective date. 80 Stat. 1599 “(3) During the period beginning on such effective date and ending on the date of such initial assignment, each person holding the position of school principal on such effective date shall have his compensation fixed m accordance with the rate of compensation prescribed for that service step, corresponding to his creditable years of service, of principal level I in that group within salary class 6 which corresponds to his academic qualifications. Each such person shall be paid for such period the difference, if any, between the amount of compensation he received during such period and the amount of compensation that he would have been paid during such period if his compensation had been fixed in accordance with the rate of compensation prescribed for the principal level in salary class 6 to which his position was assigned. “(e) On July 1, 1967, and on July 1 or each year thereafter, the Hoard of Education, with the cooperation of the Board of Commissioners of the District of Columbia, shall evaluate the duties and responsibilities of each position of school principal on the basis of the factors prescribed in paragraph (1) of subsection (d) to determine whether the principal level within salary class 6 to which such position is assigned is commensurate to the duties and responsibilities of such position. The Board of Education may assign a position of school principal to a different principal level within salary class 6 only if it determines on the basis of three consecutive annual evaluations that such assignment should be made. A person holding a position of school principal which the Board of Education has assigned to a different principal level shall not be placed in a lower service step in the new principal level than the service step he occupied immediately prior to such assignment.” (5) Subsection (a) of section 7 (D.C. Code, sec. 31–1532(a)) is amended to read as follows: “(a) (1) Each employee who is newly appointed or reappointed to any position in salary classes 3 to 15, inclusive, of the salary schedule in section 1 shall be assigned to the service step numbered next above the number of years of service with which he is credited for the purpose of salary placement. The Board, on the written recommendation of the Superintendent of Schools, is authorized to evaluate the previous experience of each such employee to determine the number of years with which he may be so credited. Employees newly appointed, reappointed, or reassigned to any position in salary class 15 shall receive one year of such placement credit for each year of satisfactory service, not exceeding nine years, in the District of Columbia in salary class 15, or in the same type of position regardless of school level, in an educational system or institution of recognized standing outside the District of Columbia public schools, as determined by the Board. Employees newly appointed, reappointed, or reassigned to any position in salary classes 3 to 14, inclusive, except the positions of chief librarian and assistant professor, associate professor and professor, shall receive no placement credit for educational service or trade experience outside the District of Columbia public schools. Employees reappointed or reassigned to positions in salary classes 3 to 14, inclusive, shall receive one year of placement credit for each year of satisfactory service in the same salary class or in a position of equivalent or higher rank within the District of Columbia public schools, except that no such employee shall receive more than five years of placement credit for previous service rendered as a temporary employee within such system. Persons appointed to the position of shop teacher in the vocational education program shall receive one year of placement credit for each year of approved experience in the 80 Stat. 1600trades, as determined by the Board but not in excess of nine years for any combination of trade experience and educational service outside the school system. Employees newly appointed or reappointed to positions of assistant professor (salary class 13), chief librarian and associate professor (salary class 11), and professor (salary class 8) shall receive one year of placement credit for each year of satisfactory service, not in excess of five years, in a position of the same or higher rank in a college or university of recognized standing outside the District of Columbia public schools, as determined by the Board. “(2) Salary placement credit for service rendered either inside or outside the public school system of the District of Columbia shall be effective on the date of appointment or on the first day of the twelfth month prior to the date of approval of such placement credit by the Board, whichever is later. “(3) Each probationary or permanent employee in salary class 15 who is in the employ of the Board of Education on the effective date of this paragraph shall move to the numerical service step or longevity step, as the case may be, commensurate with the additional creditable service allowed such employee under the amendments made by the District of Columbia Teachers’ Salary Act Amendments of 1966.” (6) Section 9 (D.C.
