COSTA MESA — The school board on Tuesday plans to recognize the schools with the most-improved test scores.
Back Bay High, Early College High, Sonora Elementary, Ensign Intermediate and Costa Mesa Middle/High schools will be honored for achieving the largest increase on the 2011 Academic Performance Index (API) statewide tests.
API scores, which range from 200 to 1,000, measure academic performance levels and growth for individual schools and for districts.
Scores are based on the results of the Standardized Testing and Reporting (STAR) program and the California High School Exit Examination.
