2005–06 APR Glossary-API Chart

Glossary of terms for the API Chart section of the 2006 API Growth Report.

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

2005 API

The 2005 API summarizes a school's or LEA's performance on the spring 2005 Standardized Testing and Reporting (STAR) Program and 2005 California High School Exit Examination (CAHSEE). It serves as the baseline score, or starting point, of performance and is also referred to as the 2005 API Base.

2006 API

The 2006 API summarizes a school's or LEA's performance on the spring 2006 STAR Program and 2006 CAHSEE. It is compared to the 2005 API Base to determine growth in the API and is also referred to as the 2006 API Growth.

Growth in the API from 2005 to 2006

The 2005 API is subtracted from the 2006 API to determine how much the school or LEA grew between 2005 testing and 2006 testing, also referred to as 2005–06 API Growth.

Met 2005–06 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 2005 API Base and the statewide performance target of 800 (minimum growth of one point). If the school’s 2005 API Base is 800 or more, the schoolwide API growth target is to maintain an API of 800 or more on its 2006 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 schoolwide growth target if its 2005–06 API Growth is at or above its 2005–06 API 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 2005 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.

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, which in most cases are 80 percent of the 2005–06 schoolwide growth target. 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 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 2005 to 2006 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 2005 API Base and 2006 API Growth reports comprise the 2005–06 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 2006 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.
