Section 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.
