MADISON, Wis. (AP) -- Unusually high fluctuations in scores for more than 150 Wisconsin schools and two dozen districts are throwing into question their school report card results.
The scores of 162 schools and 24 districts were flagged for parents, teachers, community members and others who look them up.
State Department of Public Instruction officials say it is unclear whether the changes accurately reflect what happened or are the symptom of statistically volatility.
This is the second year for the current format of the report card that is issued for all 2,447 schools and 422 districts.
Education officials defended the annual score card as a meaningful tool to measure districts and individual schools, despite the caveats.
There were 117 schools that received a failing grade this year, with 40 percent of them in Milwaukee.
