Subject to the requirements of Article 29 and except as otherwise agreed by the parents, school and regional superintendent, the school from which a student is administratively transferred shall provide for any transportation that the transfer necessitates, if transportation is required pursuant to Section 29-3. The regional superintendent shall coordinate all transportation arrangements with transferring school districts. The regional superintendent may also arrange for cooperation between school districts in the regional superintendent’s educational service region regarding the transportation needs of transferred students in order to reduce the costs of that transportation and to provide greater convenience for the students involved.
