On Friday, the Illinois State Board of Education releases the latest data on school achievement. The new online report cards for each Illinois public school offer data on teacher retention, the percentage of high school freshmen deemed “on track” for graduation and even survey results for how safe students feel at school. The report cards also will show achievement results by gender, race, ethnicity, and income level. The state says the report cards can help families decide which school is best for their child.
