Preschool through third grade (P-3) alignment is regularly named as a key aspect of early childhood education and the transition to formal schooling.

This study examined whether pre-K benefits persist through the end of first grade and the extent to which persistence differs based on outcome domains, subsequent classroom environments, and key subgroups of children. Data from 2,351 children living in a large and diverse county in Virginia revealed that the initial benefits of pre-K for academic…

Researchers have proposed integration as an approach to effectively teach social studies in primary grades.
