New York Consolidated Laws, Education Law - EDN § 1903. Powers of board of education;  laws applicable

1. The board of education of a central high school district shall have jurisdiction over the pupils residing therein who have completed the work of the sixth grade and shall have the same powers and duties in respect to the school therein as a board of education of a union free school district has, under this chapter, in respect to the schools in such district.  Except as otherwise provided in this article, the provisions of this chapter as to the courses of study, the qualifications and employment of teachers and the maintenance, conduct and supervision of public schools in union free school districts shall apply to a central high school district.

2. Where the district has provided transportation to students enrolled in such district to a school sponsored field trip, extracurricular activity or any other similar event, it shall provide transportation back to either the point of departure or to the appropriate school in the district, unless the parent or legal guardian of a student participating in such event has provided the school district with written notice, consistent with district policy, authorizing an alternative form of return transportation for such student or unless intervening circumstances make such transportation impractical.  In cases where intervening circumstances make transportation of a student back to the point of departure or to the appropriate school in the district impractical, a representative of the school district shall remain with the student until such student's parent or legal guardian has been (a) contacted and informed of the intervening circumstances which make such transportation impractical and (b) such student had been delivered to his or her parent or legal guardian.
