Early childhood education shapes cognitive growth, school readiness, and long-term outcomes—but results vary by program quality, teacher training, and who can enroll. This page examines enrollment and public spending in the US alongside international access and investment levels. It also connects cognitive gains and test-score improvements to workforce conditions, including quality ratings, teacher credentials, and staffing.
