The Virginia Dept of Education has released the SOL test results for the 2014-2015 school year - they are available here: http://www.doe.virginia.gov/statistics_reports/accreditation_federal_reports/index.shtml#passrates. You can also find a summary of the high level results (thanks, John Brett) for FCCPS here: http://126.96.36.199/~web/fccps/main/data/set/sol/227-sol
I'll need to spend some time with the data, but here is a quick summary of the FCCPS-wide results. First, passage rates for the all-students group rose in English Reading, English Writing, and History and Social Studies, stayed the same in Math, and dropped one point in Science. All were in the 90s with both Math and Science at 90.
Economically-disadvantaged students had some significant jumps and a drop of only one point in Mathematics.
Students with disabilities had a significant jump in English Writing, from 58 to 72, and a significant drop in Science, from 69 to 59.
