• Each school is assigned an API Growth target by the state, determined by calculating 5% of the difference between the Base API and 800, or a minimum of 1 point growth. Schools with APIs at or above 800 must maintain a minimum API of 800.
• To encourage schools to improve achievement for all students, the state computes APIs and sets improvement targets for the different student subgroups at the school.
• The state reports APIs for schools that test a minimum of 85% of eligible students in any subject.

About the tests

• In 2006-2007 California used the California Standards Tests (CSTs) to test students in English language arts and math in grades 2 through 11; science in grades 5, 8 and 10; and history-social science in grades 8 and 11. Middle and high school students also took subject-specific CSTs in math and science, depending on the course in which they were enrolled.
• The CSTs are standards-based tests, which means they measure how well students are mastering specific skills defined for each grade by the state of California.
• The goal is for all students to score at or above proficient on the tests.
