Section 1002.68(2), F.S., requires every private provider and public school in the VPK program to participate in a program assessment of each VPK classroom. The statute requires the program assessment to measure the quality of teacher-child interactions, including emotional support, classroom organization, and instructional support for children ages 3 to 5 years. Rule 6M-8.621, F.A.C., implements the VPK program assessment requirements as statutorily mandated. The rule establishes private and public school VPK program assessment responsibilities, provides program assessment frequency guidelines, establishes the minimum threshold score and the program assessment composite score calculation and outlines administration notification procedures.
