The report explores the impact of teacher sorting, or the tendency for high-achieving students to be assigned to more effective teachers, on student achievement. It finds that teacher sorting has a significant positive effect on student achievement in both math and English language arts. The effects are particularly strong for students who start out low-achieving. The report argues that policies aimed at reducing teacher sorting, such as random assignment of students to teachers, may be counterproductive for student achievement.

A study conducted for the Los Angeles County Department of Public Social Services aimed to determine the supply and demand of licensed childcare in the county, with a focus on low-income communities and special types of care. The survey analyzed data at three levels: county-wide, service planning areas, and supervisorial districts. Results showed disparities in childcare supply across the county, with shortages in special types of care and little information on where childcare is needed.
