2006–07 APR Glossary-API Chart

Glossary of terms for the API Chart section of the 2007 Growth API Report.

This glossary defines key terms shown on the school, local educational agency (LEA), or state API Chart section of the 2007 Growth Academic Performance Index (API) Report, which is part of the 2006–07 Accountability Progress Reporting (APR) system. Terms described below are listed in the order in which they appear on this section of the 2007 Growth API 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. (An LEA is a school district or county office of education.)

2006 Base API

The 2006 Base API summarizes a school's, an LEA's, or the state's performance on the spring 2006 Standardized Testing and Reporting (STAR) Program and 2006 California High School Exit Examination (CAHSEE). It serves as the baseline score, or starting point, of performance.

2007 Growth API

The 2007 Growth API summarizes a school's, an LEA's, or the state's performance on the spring 2007 STAR Program and 2007 CAHSEE. It is compared to the 2006 Base API to determine how much the API grew between 2006 and 2007.

Growth in the API from 2006 to 2007

The 2006 Base API is subtracted from the 2007 Growth API to determine how much the API grew between 2006 testing and 2007 testing, also referred to as 2006–07 API Growth.

Met 2006–07 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 2006 Base API and the statewide performance target of 800 (minimum growth of five points). If the school's 2006 Base API is 800 or more, the schoolwide API growth target is to maintain an API of 800 or more on its 2007 Growth API 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 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 2006 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 do not have growth targets and will not have these items on their reports.

Comparable Improvement (CI)

This item is for school reports only. Schools met the Comparable Improvement targets if all numerically significant subgroups met their API subgroup targets. LEAs and ASAM schools do not have targets for meeting comparable improvement requirements.

Both Schoolwide and Comparable Improvement (CI)

This item is for school reports only. This item indicates whether or not the school met both its schoolwide growth target, and its numerically significant subgroups demonstrated comparable improvement (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 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 2006 to 2007 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 2006 Base API and 2007 Growth API reports comprise the 2006–07 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 2007 Adequate Yearly 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 2005 or 2006 assessments, therefore, are included in the state API, with the exception of English learners who were first enrolled in U.S. schools for less than a year.
