API Growth
API Base
Academic Performance Index (API) - 2011 Base
Palo Alto Unified
(CDS code 43-69641)

       The Academic Performance Index (API) reflects the academic performance and growth of schools and districts based on the test scores of students in grades 2 through 12. The "Base" API, built from the results of statewide testing from the previous spring, is the beginning point for measuring a district’s annual growth. Because the components of the API generally change from year to year, so does the calculation of the Base API.

    The following 2011 Base API report, released in June 2012, comes from the tests given in spring 2011. The district’s Growth API report, scheduled for release in September 2012, will be calculated in the same manner but will be based on spring 2012 tests in order to measure growth over a school year. Charter schools that are funded directly are not included in the district’s API reports.

Note: The number of schools reflects only those that received a statewide rank. Schools that do not have a valid API Base also do not have a statewide rank. Schools designated as Alternative Schools Accountability Model (ASAM) schools, such as community day, continuation, opportunity, county community, county court, and California Youth Authority, receive an API Base but do not receive an API rank. Additionally, a statewide rank cannot be calculated for a school with an API Base that also has some invalid data.

Students with Disabilities 943 700
All Students Included in Base API 8,774 926
The number of students summed across all subgroups will not be equal to the total number of students in the Base API since students selecting multiple race/ethnicity categories and students with no response to race/ethnicity are not included in any student racial/ethnic subgroup. Moreover, students contained in any of the “Other Subgroups” also are part of one of the “Ethnicities” subgroups.

Note:  Beginning with the release of the 2010 Base API, API scores are reported for all subgroups with 11 or more students. For previous years, API scores are reported only for subgroups that are numerically significant (i.e. with 100 pupils or 15% of total enrollment with at least 50 pupils with valid test scores). Regardless of whether or not an API score is reported, only subgroups that are numerically significant receive API growth targets.

Direct-funded charter schools are considered schools for API purposes and do not receive an API as a district. Therefore, pupils that attend direct-funded charter schools are not included in the table above.

The API is on a scale from 200 to 1,000, with 800 as a statewide target.

Subgroup data is not available prior to 1999-2000.
