Academic Performance Index (API) Decile Ranks,
2011 API
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 red arrow on the chart above indicates where this school ranks compared to other high schools. To calculate the rankings, the high schools are divided into 10 equal groups (deciles) according to their Base API scores. The number of the group is the school's statewide ranking: 1 is the lowest, 10 the highest. On this chart the bands are superimposed on the API scale of 200 to 1,000 to show the range of scores in each group. The lowest--and highest--ranking schools have wider ranges of API scores than the groups in the middle.

| Base Information |
|
2011 Base API
|
824
|
The API is on a scale of 200 to 1,000, with 800 as the statewide target.
|
|
2012 Growth Target
|
A
|
"A" indicates this school scored at or above the Statewide Performance Target of 800 in 2011. A school with an API of 800 or above has no growth target, but must maintain an API of at least 800.
|
|
2012 API Target
|
N/A
|
A school with an API of 800 or above must maintain an API of at least 800.

2011 Statewide Rank
|

|
Each rank has 10% of all schools of the same type; 1 is lowest, 10 is highest.
|
|
2011 Similar Schools Rank
|
3
|
Each rank has 10% of all schools of the same type; 1 is lowest, 10 is highest.
|
|
2011 School Characteristics Index (SCI)
|
180.3
|
SCI values typically range from 100 to 200. The SCI values primarily reflect student demographics and are associated with student performance on state tests. The 50 schools of the same type (i.e. elementary, middle, or high) with SCI values just above this school's SCI and the 50 schools of the same type with values just below form its comparison group of 100 most similar schools.

* 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.
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.

| Under the federal law known as No Child Left Behind (NCLB), from 2003 forward the API is also used to evaluate schools for Adequate Yearly Progress (AYP).
The complete API results and backup detail are on the California Department of Education web site. These include the API and growth targets for ethnic and socioeconomic subgroups that are "numerically significant." You will also find details of the school's demographic characteristics used for comparisons.
