Traditional definitions of school readiness have focused primarily on the skills, knowledge and abilities children need for educational success. However, these definitions have evolved in recent years to encompass a multidimensional view, adding physical and mental health, social and emotional skills, executive functioning and self-regulation, and broader family and community supports. While 16 states plus the District of Columbia currently have statutory definitions of school readiness, these vary considerably in terms of comprehensiveness. This Special Report looks at the malleable and transformative components of educational and health considerations (and their intersections) as they impact school readiness. It provides examples of innovative state programs and policies, highlights new federal financial supports and closes with state-level policy takeaways.
