San Francisco public school students are the closest they have been to meeting a state goal for standards in five core subjects since testing began a decade ago.

Each year, the state of California requires second- through 11th-grade students to take tests in math, English, science, history and social science. The state issues a score to each school, called the Academic Performance Index, or API, based on students’ performance in tests. The target score for each school is an API of 800 points on a scale of 200 to 1,000 points.
