(a) In a city having a population of one million or more, recommendations for appointment to the teaching service shall be from the first three persons chosen by random selection from the qualifying eligible lists prepared by the chancellor. Competitive eligible lists in existence at the time of enactment of this subdivision shall not be merged and any such lists shall be exhausted or have expired before nominations are made from a qualifying list of a subsequent date promulgated hereunder. Qualifying eligible lists for supervisory positions shall be merged with any subsequently promulgated lists in the same license area so that there shall be one continuing non-expiring eligible list for each license area. No competitive eligible list shall remain in force for a longer period than four years, nor have a life of less than three years. No competitive eligible list now in force shall terminate any sooner than four years from the date on which it was promulgated.

(b) Qualifying eligible lists for teaching and supervisory positions shall consist of the names of all persons who have met the eligibility requirements for appointment as defined by the chancellor pursuant to sections two thousand five hundred ninety-j and two thousand five hundred sixty-nine of this chapter. Where the regulations of the commissioner do not identify a state certificate that corresponds to a license utilized by the city school district, the chancellor shall develop and administer an examination appropriate to the license, provided the development of such examination and the passing score are based upon appropriate validity studies conducted in accordance with professional standards of measurement. For teaching service positions, competitive eligible lists in existence on the effective date of this paragraph shall not be merged. Subsequently promulgated qualifying eligible lists in the same license area shall be merged so that there shall be one qualifying eligible list for each license area.

This paragraph does not affect the examinations for teaching or supervisory service positions announced by the board of examiners prior to the effective date of this paragraph.

(i) Each year, the chancellor shall direct the division of personnel to select by random selection from among candidates who are available for assignment and who are on the qualifying eligible lists for teaching positions in existence on such date for each license area, a list of prospective appointees deemed to be sufficient to meet the needs of the school system for the next school year. The random selection to establish the initial list of prospective appointees shall be held prior to April first, nineteen hundred ninety-one. In any instance where the list of prospective appointees is insufficient for the twelve month period, the chancellor shall direct the division of personnel to select by random selection additional candidates who are available for assignment and who are on qualifying eligible lists in order to compile a supplementary list of prospective appointees.

(ii) Candidates selected by a random selection system and whose names appear on the list of prospective appointees for teaching positions shall be assigned to community districts and to divisions under the jurisdiction of the chancellor in the order in which their names were selected by such system provided that each appointment by the chancellor or community board as appropriate shall be made from among the first three persons so assigned.

(iii) Lists of prospective appointees for teaching positions shall not be merged and a list shall be exhausted or have expired before assignments are made from a list of prospective appointees selected by a random selection procedure of subsequent date. No candidate shall remain on the list of prospective appointees longer than seven years from the date that the candidate was placed on the qualifying eligible list. 10-a. In the city school district of the city of Buffalo, members of the teaching and supervising staff appointed on or after the effective date of this subdivision shall be required to hold a state teaching certificate, but shall not be required to hold a license issued by the Buffalo city school district. Persons appointed to the teaching and supervising staff prior to such effective date may continue to serve under a license issued by such city school district and the board of education shall be authorized to issue permanent licenses and permanent certificates of appointment after such effective date to such persons who fulfill all announced requirements for the position that were imposed at the time of appointment. Nothing in this chapter shall affect the rights of persons serving pursuant to appropriate licenses issued prior to the effective date of this subdivision or require such persons to obtain certifications or licenses not previously required of them. 11. In a city have a population of one million or more, the board of education, subject to the approval of the commissioner of education, shall have power to authorize the superintendent of schools to assign any teacher employed to teach any subject or subjects other than any specific subject for which such teacher is licensed. No such assignment shall be made unless the superintendent of schools shall have certified that such teacher is competent to teach the assigned subject or subjects. The superintendent of schools with the approval of the board of education, shall have power to make rules and regulations in relation to ascertainment of competency of teachers to teach such assigned subject or subjects. The assignment of a teacher to teach any such assigned subject shall not operate to change the rank or level of such teacher from that which he or she occupied prior to such assignment. 12. The salaries of all members of the supervising and teaching force and of all employees and for all positions authorized under section twenty-five hundred four of this article shall continue to be not lower than such salaries were on June eighth, nineteen hundred seventeen. Rules and regulations shall be adopted governing excusing of absences and for the granting of leaves of absence either with or without pay. 13. Teachers appointed in the schools or classes maintained in the institutions controlled by the department of correction of the city of New York shall be appointed by the commissioner of correction of such city upon the nomination of the superintendent of schools of such city and shall be licensed by the board of examiners of the board of education of such city. 15. Notwithstanding any other provision of this section no period in any school year for which there is no required service and/or for which no compensation is provided shall in any event constitute a break or suspension of probationary period or continuity of tenure rights of any of the persons hereinabove described. 16. In the city school district of the city of New York, the board of education shall ascertain prior to August first, nineteen hundred sixty, and annually thereafter the number of appointments which will be required for the duration of not less than a term of the ensuing school year by reason of leaves of absence granted to members of the teaching staff serving on tenure. The board shall thereupon establish and make appointments to positions of replacement teachers in a number which, including any such teachers already serving as a result of earlier appointment, shall be at least equal, if possible, and, if not, as nearly as possible, to two-thirds of the minimum number of such teachers expected to be absent on leave at any one time. Such positions shall constitute a pool from which the board shall assign teachers to replace the teachers who are absent on leave. Appointments to such positions of replacement teachers shall be made from the appropriate eligible lists for the positions for which such replacement teachers will be required as determined by the board. Such positions of replacement teachers shall be in all respects permanent positions in the school system and persons duly appointed by the board to such positions shall be entitled to the rights of tenure and retirement accruing to persons serving in other permanent teaching positions, except that no replacement teacher shall be entitled to the special limitation of the probationary period to one year provided for certain teachers by subdivision one of this section. Upon acceptance of appointment as replacement teacher, the name of each such appointee shall be placed on a preferred eligible list as a candidate for appointment to any permanent teaching position for which he holds a valid license and such candidates shall be entitled to appointment from such preferred eligible list in order of their placement on such list. At any time when the total number of positions of replacement teacher in such pool exceeds the total number of teachers who will be absent on leave for the ensuing term of school, the board may abolish positions in such pool which are in excess of the number of teachers to be absent on leave as aforesaid, or may use replacement teachers in such pool instead of substitute teachers to replace teachers who are absent for shorter periods than one term. Whenever a particular replacement teacher cannot be used to replace any teacher who is absent on leave for a full term, he may similarly be used to replace teachers who are absent for shorter periods. Nothing herein contained shall be construed as preventing the appointment of regular substitute teachers to replace teachers absent on leave when no persons holding positions created pursuant to this subdivision are available for such replacement. 17. In the city school district of the city of Buffalo, the board of education shall, within sixty days of the effective date of this subdivision and annually prior to August first of each year thereafter, ascertain the number of appointments which will be required for the duration of not less than a term of the ensuing school year by reason of leaves of absence granted to members of the teaching staff serving on tenure. The board shall thereupon establish and make appointments to positions of replacement teachers in a number which, including any such teachers already serving as a result of earlier appointment, shall be equal, if possible, or as nearly as possible, to two-thirds of the minimum number of such teachers expected to be absent on leave at any one time. Such positions shall constitute a pool from which the board shall assign teachers to replace the teachers who are absent on leave. Such positions of replacement teachers shall be in all respects permanent positions in the school system and persons duly appointed by the board to such positions shall be entitled to the rights of tenure and retirement accruing to persons serving in other permanent teaching positions, except that no replacement teacher shall be entitled to the special limitation of the probationary period to one year provided for certain teachers by subdivision one of this section. Upon acceptance of appointment as replacement teacher, the name of each such appointee shall be placed on a preferred eligible list as a candidate for appointment to any permanent teaching position for which he or she holds a valid license and such candidates shall be entitled to appointment from such preferred eligible list in order of their placement on such list. At any time when the total number of positions of replacement teacher in such pool exceeds the total number of teachers who will be absent on leave for the ensuing term of school, the board may abolish positions in such pool which are in excess of the number of teachers to be absent on leave as aforesaid, or may use replacement teachers in such pool instead of substitute teachers to replace teachers who are absent for shorter periods than one term. Whenever a particular replacement teacher cannot be used to replace any teacher who is absent on leave for a full term, he or she may similarly be used to replace teachers who are absent for shorter periods. Nothing herein contained shall be construed as preventing the appointment of regular substitute teachers to replace teachers absent on leave when no persons holding positions created pursuant to this subdivision are available for such replacement.
