API Growth (2008-2009)
712 (2009 Growth) 681 (2008 Base) The Academic Performance Index (API) system is based on year-over-year test score performance through a two-year cycle. The Base score is for the first year and the Growth score is for the second year. Comparing the API Growth to the Base shows whether or not this school's test score performance improved between spring 2008 and spring 2009 (as reported in September 2009). The API ranges between 200 and 1000, with 800 as the statewide goal for all schools.

	This School	Middle Schools That Met Targets Statewide
Met its 2009 schoolwide growth target	Yes	74%
Met all subgroup growth targets	Yes	46%

• 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 5 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.

English Language Learners The results shown here reflect the school's Growth API for the 2008-2009 school year for all students and for each of the major subgroups of students as reported by the state. The 2009 API Growth is calculated using test score results from spring 2009.

2008 API Statewide Rank
The API Statewide Rank ranges from 1 to 10. A rank of 10, for example, means that the school's API fell into the top 10% of all schools in the state with a comparable grade range. The 2008 Statewide Rank is based on the results of tests that students took in spring 2008.

2008 API Similar Schools Rank
To create the Similar Schools Rank, the California Department of Education compares this school's test scores to 100 schools across the state with similar demographic profiles. California uses parent education level, poverty level, student mobility, student ethnicity and other data to identify similar schools.

About the tests

• In 2008-2009 California used the California Standards Tests (CSTs) to test students in English language arts in grades 2 through 11; math in grades 2 through 7; 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.

• The different student groups are identified by the California Department of Education; if there are fewer than 10 students in a particular group in a school, the state doesn't report data for that group.
• The goal is for all students to score at or above proficient on the tests.
