1. California Department of Education Policy and Evaluation Division
Calculation Spreadsheets for the 2007 Base API and 2008 Growth API
The following spreadsheets may be used to estimate a school's 2007 Base Academic Performance Index (API) or its 2008
Growth API. Schools must have valid test scores from at least 100 students to obtain an API. Schools that have between 11
and 99 valid test scores will receive an API denoted with an asterisk to indicate greater statistical uncertainty associated with
fewer scores.
The grade spans of the calculation spreadsheets have changed from the previous API reporting cycle. For the 2007-08 cycle,
calculation spreadsheets are provided for the following grade spans:
● Grade 2
● Grades 3-5 Students with Disabilities (SWD) Only*
● Grades 3-5 Students with Disabilities Not Included* (Non-SWD)
● Grade 6
● Grades 7-8
● Grades 9-12
● Bridge Schools that Cross Grade Spans
*A "Student with Disability" is defined as a student record that shows a valid Primary Disability code (other than 000).
Instructions
1. Select the spreadsheet(s) for your grade levels from the tabs below.
2. Apply the inclusion/exclusion and adjustment rules and valid API criteria to student test results. Refer to the rules in the
2007-08 Academic Performance Index Reports Information Guide on the API Web page at http://www.cde.ca.gov/api/.
3. Enter the number of students for whom there is a valid test score into each Performance Level/Band and Subject Area for the:
● California Standards Tests (CSTs), Grades 2-11
● California Alternate Performance Assessment (CAPA), Grades 2-11
● California Achievement Test, Sixth Edition Survey (CAT/6 Survey), Grades 3 and 7
● California High School Exit Examination (CAHSEE), Grades 10-12
4. Verify that all cells for Performance Level/Band and Content Area contain either a numerical entry or 0.
5. Schools or local educational agencies (LEAs) that "bridge" two or more spreadsheets will follow steps 1 through 4 above for each
spreadsheet for which they have a grade span. The calculated API score will be shown on the final "Bridge" spreadsheet.
