Glossary for the 2005 APR-API Chart

Academic Performance Index (API) Chart section of the glossary for the 2005 Accountability Progress Report (APR).

This glossary defines key terms shown on the API Chart sub-report of the 2005 Accountability Progress Report. Terms described below are listed in the order in which they appear on the sub-report.

State Accountability: Academic Performance Index (API)

State legislation, the Public Schools Accountability Act (PSAA) of 1999 (Chapter 3, Statutes of 1999), established the Academic Performance Index (API), which summarizes a school's or local educational agency's (LEA) academic performance and progress on statewide assessments. The API also is used as an additional indicator for federal Adequate Yearly Progress (AYP) requirements.

2004 API

The 2004 API score summarizes a school's or LEA's performance on the spring 2004 Standardized Testing and Reporting (STAR) Program and 2004 California High School Exit Examination (CAHSEE). It serves as the baseline score, or starting point, of performance and is also referred to as the 2004 API Base.

2005 API

The 2005 API score summarizes a school's or LEA's performance on the spring 2005 STAR Program and 2005 CAHSEE. It is compared to the 2004 API Base to determine growth in the API and is also referred to as the 2005 API Growth.

Growth in the API from 2004 to 2005

The 2004 API score is subtracted from the 2005 API score to determine how much the school or LEA grew between 2004 testing and 2005 testing, also referred to as 2004–05 API Growth.

Met schoolwide 2004–05 API growth target

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. Under state requirements, the API target varies from school to school and depends on a school's 2004 API Base score. If the school's 2004 API Base is less than 800, the schoolwide API growth target is 5 percent of the difference between the school's 2004 API Base and the statewide performance target of 800 (minimum growth of one point). If the school's 2004 API Base is 800 or more, the schoolwide API growth target is to maintain an API of 800 or more on its 2005 API Growth score. LEAs and schools in the Alternative Schools Accountability Model (ASAM) do not have API growth targets. 

A "Yes" for this item means that the school met its 2004–05 API Growth target, and a "No" means it did not.  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 2004 API Base, (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 do not have growth targets and will not have these items on their reports.

API Scores

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

Because of concerns for student confidentiality, an API is not shown for a school or 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 2004 to 2005 also is not shown.

APIs are reported according to cycles.  Each annual API reporting cycle includes two reports: a base report, which appears after the first of the calendar year, and a report of API growth, which appears after school starts in the fall. This pair of reports comprises an API reporting cycle. The 2004 API Base and 2004–05 API Growth reports comprise the 2004–05 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).

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).

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 county office of education, results for "LEA" include only schools administered directly by the county office of education; however, results for "County" include all schools in the county.

Note: A 2005 Accountability Progress Report is calculated for the state as a whole. On this report, the state API is calculated in the same way as the API for a school or LEA except that the mobility exclusion does not apply. All students taking the 2004 or 2005 assessments, therefore, are included in the state API.
