(a) Notwithstanding subdivision (d) of Section 35035, the superintendent of a school district may not transfer a teacher who requests to be transferred to a school offering kindergarten or any of grades 1 to 12, inclusive, that is ranked in deciles 1 to 3, inclusive, on the Academic Performance Index if the principal of the school refuses to accept the transfer.

(b) The governing board of a school district may not adopt a policy or regulation, or enter into a collective bargaining agreement, that assigns, after April 15 of the school year prior to the school year in which the transfer would become effective, priority to a teacher who requests to be transferred to another school over other qualified applicants who have applied for positions requiring certification qualification at the school.

(c) The prohibitions in this section shall become operative on January 1, 2007. If the prohibitions in this section are in direct conflict with the terms of a collective bargaining agreement in effect on January 1, 2007, the prohibitions of this section shall become operative on the employees governed by that agreement upon its expiration.
