The term “P-3” reflects both a mindset and a long-term approach to supporting young learners before formal school entry (Pre-school) with those in the primary grades of elementary school (K-3). The vision for P-3 is to improve the quality and coherence of children’s learning opportunities, from the experiences children have before they enter the K-12 system and extending through elementary school. Ultimately, comprehensive P-3 approaches hold the potential to improve child outcomes and to prevent or close achievement gaps (Kauerz & Coffman, 2019).
