The summer kindergarten program may be held within the school district or, pursuant to a contract that must be approved by the State Board of Education, may be operated by 2 or more adjacent school districts or by a public or private university or college. Transportation for students attending the summer kindergarten program shall be the responsibility of the school district. The expense of establishing, maintaining, and operating the summer kindergarten program may be paid from funds contributed or otherwise made available to the school district for that purpose by federal or State appropriation.
