Preschools and socio-eonomics report

Few poor, minority children enrolled in best preschools
Only 15% of the disadvantaged California children who would benefit most from strong preschools are actually enrolled in the best programs. The results of the study show that (1) use of center-based early care and education (ECE) is the norm for these children; (2) Latinos and socioeconomically disadvantaged children use it least; (3) these programs fall short on key quality benchmarks, especially those linked to early learning; (4) groups with lower levels of school readiness and later school achievement are least likely to participate in the programs that most promote school success; and (5) there is room for improvement in quality across the board and in raising participation for targeted groups.
