Early Learning Network (ELN) teams released a set of briefs focused on four impact areas -- factors open to change or improvement -- that have potential to narrow opportunity gaps and help children maintain early learning success as they transition from prekindergarten (pre-K) to elementary school and beyond. The primary goal of these briefs is to inform practice and policy decisions that support equitable and effective learning opportunities for children. This report highlights the network's collective research associated with the impact area of Pre-K Participation, including a key takeaway, action steps for practice, policy and research, and insights from the field.
