The STL Pre-K Cooperative is increasing Kindergarten readiness city wide.

Founded in the 2020-2021 school year, the Cooperative has welcomed new partners, added new classrooms, and grown the number of students served in its classrooms every year.

With student achievement as our North Star, the Cooperative's partners have adopted a common set of assessment tools to measure student growth and inform instruction as well as program design.

  • The Pre-K Observation Form (PKOF) and the Kindergarten Observation Form (KOF) are the Cooperative’s summative student assessment tools, administered twice per year

  • The Desired Results Developmental Profile (DRDP) is the Cooperative’s formative student assessment tool. It is administered three times throughout the year, providing a snapshot of student learning at the start, mid-point, and end of the school year

  • The Classroom Assessment Scoring System (CLASS) is used to measure student-teacher interactions at the start and end of the school year

Together, these data points offer a comprehensive picture of program effectiveness. The Cooperative’s shared norms both set a common high bar for student achievement and address the need for increased coherence within the early education sector and across the pre-K and K-12 continuum.

2022-2023 PKOF Results by Developmental Domain

2021-2022 PKOF Results by Developmental Domain

In the 2021-2022 school year, PKOF results reflected significant student growth across developmental domains; Kindergarten readiness levels more than doubled in all but one domain between the Fall pre-test and year-end results.

The Cooperative is making steady progress towards our goal of 85% of children ready for Kindergarten. During the 2022-2023 school year, 29% of students in Cooperative classrooms started the year ready for Kindergarten. By May 2023, 72% of students entering Kindergarten met the Kindergarten readiness standard.
