The good old API (Academic Performance Index) reports have just come out, assigning schools a rank from 1 to 10 based on how their 2007 test scores measured up to all the others in the state.
In case you were wondering, these “2007 Base API” scores aren’t exactly new results. They are just re-jiggered figures based on last year’s scores, which were released in August. The scores that came out today, on a scale of 200-1,000, reflect the latest formula the state has settled on for the 2008 API (based on the various state tests that kids take each year).
I plopped the scores and statewide rankings (as well as a “similar schools” rank that is supposed to compare schools to 99 others with similar demographics) into a spreadsheet and sorted from highest to lowest API base score.
In all, 130 Oakland schools received state rankings. According to my calculations, 13 of them earned a 9 or 10, meaning that their scores were in the top 20 percent. On the other end, 86 rank a 1 or 2 — the bottom 20 percent.
Of course, as API scores statewide have risen, a school could find itself with a lower ranking despite higher scores. Here are charts created by the California Department of Education that show the change, over the years, in what elementary, middle and high schools need to score to land in a particular percentile.
Notice any interesting trends?
