Academic Performance
Student Growth
CA State Testing (2023-24)
Growth measures how much students are learning each year, regardless of their starting point. A school with low proficiency but high growth is accelerating learning. Proficiency measures how many students are at or above grade level right now.
Growth = % of students achieving 105%+ of expected growth on the CAASPP (California Assessment of Student Performance and Progress), the annual state standardized test for grades 3–8. Proficiency = % meeting or exceeding grade-level standards.
Sources: 2024-25 SARCs, 2025-26 SPSAs, 2025-26 LCAP, HR data briefing (Feb 2026). Proficiency from 2023-24 CA state testing. Student growth from 2024-25 evaluations.
