Nearly three-quarters of San Francisco public schools maintained or improved their state rankings, but the rest lost ground, according to data released by the California Department of Education on Thursday.
Statewide rankings are determined by comparing and sorting schools into 10 groups according to their Academic Performance Index, which is based largely on test scores from the previous year. Each group represents 10 percent of schools. The schools are compared with all schools statewide as well as with schools that are demographically similar.
In the San Francisco Unified School District, 74 percent of elementary schools, 69 percent of middle schools and 72 percent of high schools improved or maintained their rankings.
Forty-three percent of SFUSD schools were labeled above average, with rankings of 7 or higher. Another 43 percent were below average, with rankings between 1 and 4. There were 20 schools with a 1, the lowest ranking.
Most of these were schools in the Superintendent’s Zones, designated areas in the Mission and the Bayview which have received extra money and attention as part of a school improvement program.
