Blank cell – This indicates that the school or student group did not have a valid 2011, 2012, and/or 2013 Growth API. Therefore, a 3-Year average could not be calculated.

*Assembly Bill (AB) 484 amended California Education Code sections 52052(e)(2)(F) and 52052(e)(4) to allow schools that do not have an API calculated in 2013–14 and 2014–15 to use one of the following criteria to meet legislative and/or programmatic requirements:

• The most recent API calculation;
• An average of the three most recent annual API calculations; or
• Alternative measures that show increases in pupil academic achievement for all groups of pupils schoolwide and among significant groups.

The decision to use one of the above criteria may be made on a program by program basis and is a local decision.

Formula to Calculate Average APIs:

A 3-Year Average API Report was produced if the following criteria were met:

1. The school had a valid API (i.e., the school received an API report) in each of the last three consecutive years;



2. The school had 11 or more valid scores in each of the last three consecutive years. (A valid score is when a student’s assessment results are included in the calculation of the API.); and,



3. If the above criteria are met, the 3-Year Average API Report will also include any student group(s) that had 11 or more valid scores in each of the last three consecutive years.

Non-Weighted Average: The formula to calculate the non-weighted average is:

2011 API + 2012 API + 2013 API 3

Weighted Average: The formula to calculate the weighted average is:

(2011 API x 2011 Valid Scores) + (2012 API x 2012 Valid Scores) + (2013 API x 2013 Valid Scores) 2011 Valid Scores + 2012 Valid  Scores+ 2013 Valid Scores
