This PACE study found the depth and strength of California districts’ preK–3 alignment efforts to vary considerably. As preK–3 alignment is not an explicit state priority, districts do not feel obligated to focus on it in the face of many other demands. Divergent beliefs among districts about the role and purpose of preschool can enhance or inhibit alignment efforts, as can the formal roles of district preK directors and elementary principals who have preKs on their campuses. Different licensing requirements for preK and elementary teachers as well as the complicated web of regulations associated with different funding streams influence the strength of alignment efforts. Even within these constraints, however, there are many steps districts can take to improve preK–3 alignment.
