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.

The Teaching and California's Future initiative provides policymakers with data on the teacher workforce and labor market. The initiative's annual report details teacher development policies and their impact on teacher quality and distribution. The goal is to help policymakers make informed decisions about strengthening the state's teacher workforce.

The quality of teaching and the need to expand California's ranks of excellent teachers demand urgent public discussion. We must attract the best and brightest to teaching, prepare them effectively, and support and retain them. Solutions require bipartisan leadership, not spin. This report presents the latest research and projections, highlighting that while some numbers are improving, we're likely to face severe shortages again soon and the pipeline for recruiting, preparing, and training teachers has substantial problems.

California's aging teacher workforce will lead to a significant demand for teachers, with shortages particularly in special education and secondary education. The number of underprepared teachers in low-performing schools serving minority, poor, and ELL students is disproportionate. Budget cuts have reduced funding for recruitment and professional development programs, and California's induction system needs refinement. Curriculum-based professional development programs have mainly targeted elementary school teachers, neglecting the training needs of secondary teachers.

This report argues that the state of California needs to prioritize better education for all children with a sustained long-term investment of resources and leadership. Despite political upheaval and fiscal problems, there is a consensus for better education. The authors suggest that the issue requires a response as intense and sustained as the state's response to natural disasters, and calls for a system of teacher development to ensure all teachers have the necessary knowledge and skills to meet academic standards.
