2012–13 APR Glossary-Growth API

Glossary of terms for the Growth Academic Performance Index (API) section of the 2013 Growth API Report.

This glossary defines key terms shown on the school, local educational agency (LEA), or state Growth API section of the 2013 Growth Academic Performance Index Report, which is part of the 2012–13 Accountability Progress Reporting system. Terms described below are listed in the order in which they appear in the headings on the 2013 Growth Academic Performance Index Report. More detailed information may be found in the 2012–13 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 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 special education schools do not currently have growth or target information.

Number of Students Included in the 2013 Growth API

This is the number of students with valid scores that contribute to the school's, an LEA's, or the state's 2013 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

2013 Growth API

The Growth API summarizes a school's, an LEA's, or the state's performance on the 2013 Standardized Testing and Reporting (STAR) Program and 2013 California High School Exit Examination (CAHSEE) tests. The API is on a scale of 200 to 1000. The 2013 Growth API is based on the performance of individual students on the following tests administered in spring 2013:

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

2012 Base API

The 2012 Base API summarizes a school's, an LEA's, or the state's performance on the 2012 STAR Program tests and on the 2012 CAHSEE.

2012–13 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
2012–13 Growth

The 2012–13 Growth is calculated by subtracting the 2012 Base API from the 2013 Growth API.

Met Growth Target

Schoolwide

This item is for school reports only. A school met its schoolwide growth target if its 2012–13 Growth is at or above its 2012–13 Growth Target. LEAs and special education 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 student group targets. The growth target for a student group is calculated in the same way as the target for a school. LEAs and special education schools do not have growth targets. For a full description of targets, see "2012–13 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 all 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 2012 Base API were calculated using all 100 schools in this school's 2012 similar schools group. When the 2013 Growth data became available, the growth data from the same 100 similar schools was used to calculate the 2013 median Growth API. This comparison group was based on the following characteristics:

Student Groups

Number of Students Included in the 2013 API

This is the number of students with valid STAR Program scores that contribute to the student group's 2013 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" (EL) is defined as:

"Students with Disabilities" (SWD) are defined as:

These data are based on the results of the spring 2012 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

2013 Growth

The 2013 Growth API summarizes a student group's performance on the spring 2013 STAR Program and 2013 CAHSEE.

2012 Base

The 2012 Base API summarizes a student group's performance on the spring 2012 STAR Program and 2012 CAHSEE. It serves as the baseline score, or starting point, of performance of that student group.

2012–13 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
2012–13 Growth

This item is for school reports only. The student group's 2012–13 Growth is calculated by subtracting its 2012 Base API from its 2013 Growth API.

Met Student Group Growth Target

This item is for school reports only. A student group met its growth target if its 2012–13 Growth is at or above its 2012–13 Growth Target.

Statewide and Similar Schools Ranks

2013 Statewide Rank

This item is for school reports only. Schools are ranked in ten categories of equal size, called deciles, from one (lowest) to ten (highest). A school's statewide rank compares that school to other schools of the same school type in the entire state. The school types are elementary, middle, and high. Each decile contains 10 percent of all schools of that type. A school's statewide rank is the decile where that school's Growth API falls compared with the Growth APIs of the other schools statewide of the same school type. Special education schools and schools in the Alternative Schools Accountability Model (ASAM) do not receive statewide ranks. (Note: Contrary to prior years, the 2013 statewide ranks were produced using the Growth API and not the Base API. Because the State Board of Education [SBE] approved the State Superintendent of Public Instruction's [SSPI's] recommendation to not produce a 2014 Growth, 2014 Base, and 2015 Growth API Reports, it was not necessary to produce a 2013 Base API Report. Thus, the 2013 Growth API data were used to produce the 2013 statewide ranks. In addition, since the California Education Code [EC] Section requiring the production of API statewide and similar schools ranks was repealed, this is the final set of ranks being reported.)

2013 Similar Schools Rank

This item is for school reports only. In addition to statewide ranks, schools are ranked compared to 100 other schools with similar demographic characteristics, educational challenges, and opportunities. For the similar schools rank, schools are ranked into deciles according to school type: elementary, middle, and high. To determine the similar schools rank for a school, a comparison group of 100 similar schools of the same school type is formed for that school, based on similar demographic characteristics. The APIs for this group of 100 schools are ranked into ten categories of equal size, called deciles, from one (lowest) to ten (highest). Each decile contains 10 percent of all of the 100 similar schools in the comparison group. The school's similar schools rank is the decile where that school's Growth API falls compared with the Growth APIs of the 100 other similar schools in the comparison group. Special education schools, schools in the ASAM, and small schools with between 11 to 99 valid STAR Program scores do not receive similar schools ranks. (Note: Contrary to prior years, the 2013 similar schools ranks were produced using the Growth API and not the Base API. Because the SBE approved the SSPI's recommendation to not produce a 2014 Growth, 2014 Base, and 2015 Growth API Reports, it was not necessary to produce a 2013 Base API Report. Thus, the 2013 Growth API data were used to produce the 2013 statewide ranks. In addition, since the California EC Section requiring the production of API statewide and similar schools ranks was repealed, this is the final set of ranks being reported.)

The PSAA specifies the demographic characteristics to include in similar schools rank calculations:
