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 meeting their annual i-Ready Expected Growth target on the mid-year diagnostic. i-Ready is the district’s local K–8 literacy and math assessment; the LCAP goal is to raise this by 4 percentage points each year. Proficiency = % meeting or exceeding grade-level standards on the CAASPP (the California state test, given in spring of grades 3–8).
Sources: 2024-25 SARCs, 2025-26 SPSAs, 2025-26 LCAP, each school’s 2025-26 Board of Trustees data presentation. Proficiency from 2023-24 CAASPP. Growth from each school’s 2025-26 mid-year i-Ready diagnostic as reported to the Board.
