SF 2006 API Growth Data
The state recently released the 2006 API growth data. This growth data is a measure of how well individual schools have progressed during the past school year. The Base API can be used to compare schools. The growth data measures a school's progress compared to a prior year.
Once again, SFUSD has done very well. As they explain in this press release:
I will digest the numbers and integrate them into our library of API data files in the coming days. But for now I wanted to publish the complete raw data for all San Francisco schools. This is exactly the same data published by the state here with all other counties removed and with the document converted to a (virus-free) Excel spreadsheet.
Enjoy the good news!
Once again, SFUSD has done very well. As they explain in this press release:
The San Francisco Unified School District met its district-wide API target and improved by 10 API points reaching a district-wide API of 755. Over 70% of the schools (78 out of 111 schools) met their school-wide API targets. The greatest success was seen at the elementary school level where 82% or 60 out of 73 of the elementary and K-8 schools met their school-wide API targets[...] Superintendent Chan stated, "I am delighted that the district has so many high performing schools."I did a very quick scan of the data and came up with the following list of schools that experienced the most groowth this year:
- Alamo Elementary
- Balboa High
- Bessie Carmichael Elementary
- Bret Harte Elementary

If you are confused about the API data and what it means, check out the state's Information Guide. In it they offer the following detailed description of the Base and Growth data:
The API Base, released after the beginning of the calendar year, includes statewide results from continuing and any new assessments from the prior year. The API Base serves as the baseline for comparisons to the API Growth, and school rankings are reported for the API Base. The API Growth, released in August, is calculated in exactly the same fashion and with the same indicators as the prior year API Base but is based on test results for the following year. The API Growth determines whether schools met their API growth targets. The 2005 API Base Report, released in March 2006, is calculated from results of spring 2005 statewide testing. The 2006 API Growth Report, released in August 2006, is calculated from results of spring 2006 statewide test results. The 2005 API Base is subtracted from the 2006 API Growth to produce the 2005–06 API Growth. The API Base Report includes the API Base, growth targets, and ranks. The API Growth Report includes API Growth, growth achieved, and whether targets were met.

To what extent do these various increases in API scores reflect changing demographics of the individual schools?
KC, thanks for posting this. It's very interesting. But is there a pointer you can give us to what the various column headings mean? Most of them I figured out but as I move to the right they get harder to deceipher.
re: demographics, that's a big question. For some schools that is a major factor. For others like Vis Valley or 21st century, not so much. Offhand, the increases look very broad based.
The state API data website has all the info you could want. The 2006 record layout document explains the each colum. Most of the columns break down results by ethnicity. The really obscure stuff relates to the SCI demographics that go into the Similar Schools Rank.
