About the Study: Purpose

Now that we are in the second year of statewide TK implementation in California, we are now interested in learning about the impact of TK on students.

  • Does TK participation improve kindergarten readiness in the domains of early literacy/language, mathematics, and social emotional skills?
  • To what extent are the impacts of TK sustained through the end of kindergarten?
  • Does the impact of TK change across cohorts?
  • How do student outcomes vary by child background characteristics, such as gender, English learner status, or poverty status?
  • How do student outcomes vary by district characteristics, such as district size or urbanicity?

The TK study also aims to understand how the quality of TK is related to student outcomes.

  • How do TK programs fare on measures of classroom quality?
  • How does TK quality change across cohorts?
  • How do student outcomes vary with TK classroom quality?
  • How do student outcomes vary by program structure, such as stand-alone versus combination
    classrooms?

Relatedly, we are also interested in studying the longer term impacts of TK, in a later phase of the study.

  • Are the impacts of TK sustained through the early elementary school years?
