Finally, here are the End of Course pass rates at Richmond’s high schools for the reading and math tests:
These data must be taken with a front end loader full of salt because of Richmond’s remarkably high retest rate that VDOE kept hidden until a judge made them cough up the 2014 SGP data. Here, for example, are the 2014 algebra I retest counts in Richmond.
My analysis of those data showed that the retests increased the SOL scores of the students involved by an average of 24.6 points on a test where 400 was passing (i.e., by 6.1% of the passing score).
This year, for the first time, retests were available for elementary and middle school students. Even with that boost (about 4% according to VDOE), we have seen the Richmond middle school and far too many elementary school scores endured at appalling levels.
