2007–08 APR Glossary-Growth API

Glossary of terms for the Growth API section of the 2008 Growth API Report.

This glossary defines key terms shown on the school, local educational agency (LEA), or state Growth API section of the 2008 Growth Academic Performance Index Report, which is part of the 2007–08 Accountability Progress Reporting system. Terms described below are listed in the order in which they appear in the headings on the 2008 Growth API Report. More detailed information may be found in the 2007–08 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 Academic Performance Index (API), which summarizes a school's or 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.)

The reports for the state, for LEAs, and for schools in the Alternative Schools Accountability Model (ASAM) do not currently have growth or target information.

Number of Students Included in the 2008 Growth API

This is the number of students with valid scores that contribute to the school's, an LEA's, or the state's 2008 Growth API. It is possible for a student to have test results contributing to the component score in one content area and not another. For example, if a student did not receive a test score in English-language arts (ELA), but did receive a score in mathematics, the student's mathematics results can still be included in the API score.

API

2008 Growth API

The 2008 Growth API summarizes a school's, an LEA's, or the state's performance on the 2008 Standardized Testing and Reporting (STAR) Program and 2008 California High School Exit Examination (CAHSEE) tests. The API is on a scale of 200 to 1000. The 2008 Growth API is based on the performance of individual students on the following tests administered in spring 2008:

In addition, APIs also are calculated for numerically significant student subgroups at a school or LEA.

2007 Base API

The 2007 Base API summarizes a school's, an LEA's, or the state's performance on the 2007 STAR Program tests and on the 2007 CAHSEE.

2007–08 Growth Target

This item is for school reports only. The state PSAA growth target requirements are shown in the following table:

School or
Subgroup
2007 Base API
2007–08 Growth Target
200 - 690
5 percent of the difference between the Base API and the statewide performance target of 800
691 - 795
gain of 5 points
796
gain of 4 points
797
gain of 3 points
798
gain of 2 points
799
gain of 1 point
800 or more
must maintain an API of at least 800
2007–08 Growth

The 2007–08 Growth is calculated by subtracting the 2007 Base API from the 2008 Growth API.

Met Growth Target

Schoolwide

This item is for school reports only. A school met its schoolwide growth target if its 2007–08 Growth is at or above its 2007–08 Growth Target. LEAs and ASAM schools do not have growth targets.

All Subgroups

This item is for school reports only. Schools met this target if all numerically significant subgroups at the school met their API subgroup targets. The growth target for a subgroup is calculated in the same way as the target for a school. LEAs and ASAM schools do not have growth targets. For a full description of targets, see the section on "2007–08 Growth Target."

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 growth targets (i.e., each numerically significant subgroup met its subgroup growth target).

Met Subgroup Growth Target

This item is for school reports only. This item indicates whether or not the numerically significant subgroup met its growth target.

Similar Schools

Similar Schools

The similar schools rank indicates the decile rank of a school's API compared with the APIs of 100 other schools with similar demographic characteristics. The similar schools ranks allow schools to look at their academic performance compared to other schools with some of the same opportunities and challenges.

Median API

This item is for school reports only. The median values for the 2008 Growth API and 2007 Base API were calculated using all 100 schools in this school's 2007 similar schools group. This comparison group was based on the following characteristics:

To derive a complete listing of the 100 similar schools for a school, click on the Median API score headings (either "2008 Growth" or "2007 Base").

Subgroups

Number of Students Included in the 2008 API

This is the number of students with valid STAR Program scores that contribute to the subgroup's 2008 Growth API. It is possible for a student to have test results contributing to the component score in one content area and not another. For example, if a student did not receive a test score in ELA, but did receive a score in mathematics, the student's mathematics results can still be included in the API.

Numerically Significant Subgroups

A numerically significant subgroup for the API is defined as:

A subgroup must be numerically significant in both the base year and growth year in an API reporting cycle to have subgroup growth and target information.

Subgroup Definitions

Ethnic/racial subgroups include:

"Socioeconomically Disadvantaged" is defined as:

"English Learners" are defined as:

"Students with Disabilities" are defined as:

These data are based on the results of the spring 2008 STAR Program administration student answer document. A student who is a member of the socioeconomically disadvantaged, English learner, and/or disability subgroup is also a member of one of the racial/ethnic subgroups. Therefore, it is possible that the total percentage of students in all numerically significant subgroups at a school, LEA, or the state may exceed 100.

Subgroup API

2008 Growth

The 2008 Growth API summarizes a subgroup's performance on the spring 2008 STAR Program and 2008 CAHSEE.

2007 Base

The 2007 Base API summarizes a subgroup's performance on the spring 2007 STAR Program and 2007 CAHSEE. It serves as the baseline score, or starting point, of performance of that subgroup.

2007–08 Growth Target

This item is for school reports only. The state PSAA growth target requirements are shown in the following table:

School or
Subgroup
2007 Base API
2007–08 Growth Target
200 - 690
5 percent of the difference between the Base API and the statewide performance target of 800
691 - 795
gain of 5 points
796
gain of 4 points
797
gain of 3 points
798
gain of 2 points
799
gain of 1 point
800 or more
must maintain an API of at least 800
2007–08 Growth

This item is for school reports only. The subgroup’s 2007–08 Growth is calculated by subtracting its 2007 Base API from its 2008 Growth API.

Met Subgroup Growth Target

This item is for school reports only. A subgroup met its growth target if its 2007–08 Growth is at or above its 2007–08 Growth Target.
