2009–10 APR Glossary-Growth API

Glossary of terms for the Growth Academic Performance Index (API) section of the 2010 Growth API Report.

This glossary defines key terms shown on the school, local educational agency, or state Growth API section of the 2010 Growth Academic Performance Index Report, which is part of the 2009–10 Accountability Progress Reporting system. Terms described below are listed in the order in which they appear in the headings on the 2010 Growth Academic Performance Index Report. More detailed information may be found in the 2009–10 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 a local educational agency's (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 2010 Growth API

This is the number of students with valid scores that contribute to the school's, an LEA's, or the state's 2010 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

2010 Growth API

The 2010 Growth API summarizes a school's, an LEA's, or the state's performance on the 2010 Standardized Testing and Reporting (STAR) Program and 2010 California High School Exit Examination (CAHSEE) tests. The API is on a scale of 200 to 1000. The 2010 Growth API is based on the performance of individual students on the following tests administered in spring 2010:

  • California English-Language Arts and Mathematics Standards Tests (CSTs) in ELA and mathematics - grades two through eleven
  • California Science Standards Test (CST) in science - grades five, eight, and nine through eleven
  • California Life Science Standards Test (CST) in life science - grade ten
  • California History-Social Science Standards Test (CST) in history-social science - grades eight through eleven
  • California Modified Assessment (CMA) in ELA, mathematics, and science -
  • ELA – grades three through eight
  • Mathematics – grades three through seven
  • Science – grades five and eight
  • California Alternate Performance Assessment (CAPA) in ELA, mathematics, and science -
  • ELA – grades two through eleven
  • Mathematics – grades two through eleven
  • Science – grades five, eight, and ten
  • California High School Exit Examination (CAHSEE) in ELA and mathematics - grade ten (and grades eleven and twelve if the student retook and passed either part of the CAHSEE) 

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

2009 Base API

The 2009 Base API summarizes a school's, an LEA's, or the state's performance on the 2009 STAR Program tests and on the 2009 CAHSEE.

2009–10 Growth Target

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

School or
Subgroup
2009 Base API
2009–10 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
2009–10 Growth

The 2009–10 Growth is calculated by subtracting the 2009 Base API from the 2010 Growth API.

Met Growth Target

Schoolwide

This item is for school reports only. A school met its schoolwide growth target if its 2009–10 Growth is at or above its 2009–10 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 "2008–09 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 2010 Growth API and 2009 Base API were calculated using all 100 schools in this school's 2009 similar schools group. This comparison group was based on the following characteristics:

  • Pupil mobility
  • Pupil ethnicity
  • Pupil socioeconomic status
  • Percentage of teachers who are fully credentialed
  • Percentage of teachers who hold emergency credentials
  • Percentage of pupils who are English learners (ELs)
  • Average class size per grade level
  • Whether the schools operate multitrack year-round educational programs
  • Percentage of grade span enrollments (grades two, six, seven to eight, and nine to eleven)
  • Percentage of students in Gifted and Talented Education program
  • Percentage of students with disabilities (SWDs)
  • Percentage of reclassified fluent-English-proficient (RFEP) students
  • Percentage of migrant education students

To derive a complete listing of the 100 similar schools for a school, click on the Median API score headings (either "2010 Growth" or "2009 Base").

Subgroups

Number of Students Included in the 2010 API

This is the number of students with valid STAR Program scores that contribute to the subgroup's 2010 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:

  • 100 or more students with valid STAR Program scores

    OR

  • 50 or more students with valid STAR Program scores who make up at least 15 percent of the total valid STAR Program scores

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

Race and ethnicity subgroups include:

  • Black or African American
  • American Indian or Alaska Native
  • Asian
  • Filipino
  • Hispanic or Latino
  • Native Hawaiian or Pacific Islander
  • White
  • Two or More Races

"Socioeconomically Disadvantaged" is defined as:

  • A student neither of whose parents have received a high school diploma

    OR

  • A student who is eligible for the free or reduced-price lunch program, also known as the National School Lunch Program (NSLP)

"English Learner" is defined as:

  • A student identified as EL based on the results of the California English Language Development Test (CELDT).

    OR

  • A RFEP student who has not scored at the proficient level or above on the CST in ELA for three times after being reclassified.

"Students with Disabilities" are defined as:

  • A student who receives special education services and has a valid disability code on the student answer document

    OR

  • A student who was previously identified as special education but who is no longer receiving special education services for two years after exiting special education. This student is not counted in determining numerical significance for the SWDs subgroup.

These data are based on the results of the spring 2010 STAR Program administration student answer document.

A student who is a member of the socioeconomically disadvantaged, EL, 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, 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 subgroup's API.

Subgroup API

2010 Growth

The 2010 Growth API summarizes a subgroup's performance on the spring 2010 STAR Program and 2010 CAHSEE.

2009 Base

The 2009 Base API summarizes a subgroup's performance on the spring 2009 STAR Program and 2009 CAHSEE. It serves as the baseline score, or starting point, of performance of that subgroup.

2009–10 Growth Target

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

School or
Subgroup
2009 Base API
2009–10 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
2009–10 Growth

This item is for school reports only. The subgroup's 2009–10 Growth is calculated by subtracting its 2009 Base API from its 2010 Growth API.

Met Subgroup Growth Target

This item is for school reports only. A subgroup met its growth target if its 2009–10 Growth is at or above its 2009–10 Growth Target.
