2010–11 APR Glossary-Growth API

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

This glossary defines key terms shown on the school, local educational agency (LEA), or state Growth API 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 in the headings on 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.)

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 2011 Growth API

This is the number of students with valid scores that contribute to the school's, an LEA's, or the state's 2011 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

2011 Growth API

The Growth API summarizes a school's, an LEA's, or the state's performance on the 2011 Standardized Testing and Reporting (STAR) Program and 2011 California High School Exit Examination (CAHSEE) tests. The API is on a scale of 200 to 1000. The 2011 Growth API is based on the performance of individual students on the following tests administered in spring 2011:

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

2010 Base API

The 2010 Base API summarizes a school's, an LEA's, or the state's performance on the 2010 STAR Program tests and on the 2010 CAHSEE.

2010–11 Growth Target

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

School or
Student Group
Base API
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
2010–11 Growth

The 2010–11 Growth is calculated by subtracting the 2010 Base API from the 2011 Growth API.

Met Growth Target

Schoolwide

This item is for school reports only. A school met its schoolwide growth target if its 2010–11 Growth is at or above its 2010–11 Growth Target. LEAs and ASAM schools do not have growth targets.

All Student Groups

This item is for school reports only. Schools met this target if all numerically significant student groups at the school met their API subgroup targets. The growth target for a student group is calculated in the same way as the target for a school. LEAs special education schools do not have growth targets. For a full description of targets, see "2010-11 Growth Target."

All Targets

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

Met Student Group Growth Target

This item is for school reports only. This item indicates whether or not the numerically significant student group 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 2011 Growth API and 2010 Base API were calculated using all 100 schools in this school's 2010 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 "2011 Growth" or "2010 Base").

Groups

Number of Students Included in the 2011 API

This is the number of students with valid STAR Program scores that contribute to the subgroup's 2011 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 Student Groups

A numerically significant student group for the API is defined as:

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

Student Group Definitions

Race and ethnicity student groups include:

"Socioeconomically Disadvantaged" is defined as:

"English Learner" is defined as:

"Students with Disabilities" are defined as:

These data are based on the results of the spring 2011 STAR Program administration student answer document.

A student who is a member of the socioeconomically disadvantaged, EL, and/or disability student group is also a member of one of the race/ethnicity student groups. Therefore, it is possible that the total percentage of students in all numerically significant student groups at a school, an LEA, or the state may exceed 100. The results of ELs who were first enrolled in U.S. schools for less than a year are not included in the API count of valid scores or in a school's, an LEA's, or a student group's API.

Student Group API

2011 Growth

The 2011 Growth API summarizes a student group's performance on the spring 2011 STAR Program and 2011 CAHSEE.

2010 Base

The 2010 Base API summarizes a student group's performance on the spring 2010 STAR Program and 2010 CAHSEE. It serves as the baseline score, or starting point, of performance of that student group.

2010–11 Growth Target

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

School or
Student Group
Base API
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
2010–11 Growth

This item is for school reports only. The student group's 2010–11 Growth is calculated by subtracting its 2010 Base API from its 2011 Growth API.

Met Student Group Growth Target

This item is for school reports only. A student group met its growth target if its 2010–11 Growth is at or above its 2010–11 Growth Target.
