Finding from the 2023 LPI report's analyses, reported in the Challenges Persist section and illustrated in Figures 2 and 3. The report notes the lag "is especially apparent for K–12 school districts that enroll between 40% and 55% of their students who are identified by the LCFF as requiring additional support."

"Improvements in math and reading achievement for school districts just below the 55% concentration grant threshold lag districts above the threshold."

Related Claims¶

• Student outcome improvements from LCFF funding were more pronounced for cohorts exposed to funding increases for more of their school-age years — related
• LCFF-induced per-pupil spending increases caused improvements in math and reading achievement in districts receiving concentration grants — related
• LCFF-induced spending increases significantly improved math and reading achievement in every grade assessed, with the largest gains in districts receiving concentration grants — related
• Research on school finance reforms finds increased spending improves educational and life outcomes, with larger effects for students from low-income backgrounds, including causal evidence from California's Local Control Funding Formula — a broader claim this one bears on
• Structural and fiscal conditions—including grade-3 class-size incentive cliffs and declining enrollment—jeopardize the bilingual teacher pipeline and program sustainability — related
