2010–11 APR Glossary-API Chart

Glossary of terms of the Academic Performance Index (API) Chart section of the 2011 Growth API Report.

This glossary defines key terms shown on the school, local educational agency (LEA), or state API Chart section of the 2011 Growth Academic Performance Index Report, which is part of the 2010–11 Accountability Progress Reporting system. Terms described below are listed in the order in which they appear on this section of the 2011 Growth Academic Performance Index Report. More detailed information may be found in the 2010–11 Academic Performance Index Reports Information Guide.

State Accountability: Academic Performance Index

State legislation, the Public Schools Accountability Act (PSAA) of 1999 (Chapter 3, Statutes of 1999), established the API, which summarizes a school's or an LEA's academic performance and progress on statewide assessments. The API also is used as an additional indicator for federal Adequate Yearly Progress (AYP) requirements. (An LEA is a school district or county office of education [COE].)

2010 Base API

The 2010 Base API summarizes a school's, an LEA's, or the state's performance on the spring 2010 Standardized Testing and Reporting (STAR) Program and 2010 California High School Exit Examination (CAHSEE). It serves as the baseline score, or starting point, of performance.

2011 Growth API

The 2011 Growth API summarizes a school's, an LEA's, or the state's performance on the spring 2011 STAR Program and 2011 CAHSEE. It is compared to the 2010 Base API to determine how much the API grew between 2010 and 2011.

Growth in the API from 2010 to 2011

The 2010 Base API is subtracted from the 2011 Growth API to determine how much the API grew between 2010 testing and 2011 testing, also referred to as 2010–11 API growth.

Met 2010–11 API Growth Targets

Schoolwide

This item is for school reports only. This item shows whether the school met the state API growth target for the school as a whole (but does not include whether subgroups met growth targets). The API is used in both state and federal target criteria. The state criteria for the API differ from the federal criteria. This item shows whether the school met state criteria. Under state requirements, the schoolwide API growth target is 5 percent of the difference between the school’s 2010 Base API and the statewide performance target of 800 (minimum growth of 5 points). If the school’s 2010 Base API is 800 or more, the schoolwide API growth target is to maintain an API of 800 or more on its 2011 Growth API. LEAs and schools with an approved Alternative Schools Accountability Model (ASAM) do not have API growth targets. 

A “Yes” for this item means that the school met its schoolwide growth target. An “N/A” for this item means that the growth and growth target could not be determined because (1) the school did not have a valid 2010 Base API, (2) the school had significant demographic changes between testing years, (3) the school was in the ASAM, or (4) the API was considered to be invalid for other reasons or was not calculated due to missing data. LEAs and ASAM schools do not have growth targets and will not have these items on their reports.

All Subgroups

This item is for school reports only. Schools met this target if all numerically significant subgroups met their API subgroup targets. LEAs and ASAM schools do not have growth targets.

Both Schoolwide and Subgroups

This item is for school reports only. This item indicates whether or not the school met both its schoolwide growth target and all subgroup targets (i.e., each numerically significant subgroup met its subgroup growth target).

API Scores

An API is an index (or score) ranging from 200 to 1000 that summarizes a school's, an LEA's, or the state's performance based on student results on statewide assessments.

Because of concerns for student confidentiality, an API is not shown for a school or an LEA if the number of valid scores is less than 11. In addition, an API is not shown if the API is invalid (e.g., the results used for API calculation include too many testing irregularities, the school has experienced significant demographic change between testing years, the school has an excess proportion of parental waivers, or the percentage of students tested is too low). In these cases, the growth from 2010 to 2011 also is not shown.

APIs are reported according to cycles. Each annual API reporting cycle includes two reports: a base report, which is released after the first of the calendar year, and a report of API growth, which is released when school starts in the fall. This pair of reports comprises an API reporting cycle. The 2010 Base API and 2011 Growth API reports comprise the 2010–11 API reporting cycle. The APIs in a reporting cycle are calculated in the same fashion with the same indicators (but using test results from two different years).

API Score Chart: School, LEA, California

This item is for school reports only. “School” results on the API graphs are aggregated at the school level. “LEA” results on the API graphs are aggregated at the LEA level. “California” results on the API graphs are aggregated at the state level. Direct-funded charter schools and single-school districts are treated as schools and receive the school report. On the school report for a direct-funded charter school, the API results for “LEA” are those for the authorizing charter agency. On the school report for a single-school district, the API results for “LEA” are those of the school district (which in most cases is a repetition of the school results).

API Score Chart: LEA, County, California

This item is for LEA reports only. “LEA” results on the API graphs are aggregated at the LEA level. “County” results on the API graphs are aggregated at the county level. “California” results on the API graphs are aggregated at the state level. Direct-funded charter schools and single-school districts are treated as schools and do not receive the LEA report. When the LEA is a COE, results for “LEA” include only schools administered directly by the COE; however, results for “County” include all schools in the county.
