I have seen some analysis of WASL pass rates - White vs. African-American, trends over time, cohort following - either in the District or school-by-school. These analyses were done either by me or by other blog participants; I'm not seeing any done by the District.
Is there some analysis that folks would like to see? Honestly, these things don't take much time and I'm happy to do them. I'm as interested in the results as anyone else, so don't be shy about asking for something.
Data is available for all schools in the state, so you could see how many high schools with at least 40 students tested and without the word "Alternative" in their name had lower pass rates on the math WASL than Rainier Beach High School (there were only nine).
