Reading the numbers in context
2024–25 was a strong year: ELA climbed to 49%, math to 40%, and science to 36% — each up by several points and improving faster than the district and the state. Adelante Selby now matches the district and the state in ELA and runs ahead of both in math and science, even though most early instruction is in Spanish while the tests are given in English. On the state accountability system, the school has also exited "Additional Targeted Support" status as its student-group results improved.
