First, a bit of a disclaimer. I'm always suspicious of raw data. When I look at lists like the one just shared by School Digger, I wonder if some of these schools have different testing methods that aren't measured by their methodology? My point is that if you are really considering where you or your children should go to high school, check out the full data they've shared or even better, just do your own research.

Out of 699 Illinois high schools, here are the 10 that rank at the bottom of the School Digger list.

Some takeaways other than my suspicion about possible different testing methods? First of all, these schools showed single digit testing score averages which (if accurate) is catastrophic. Second, many are in the Chicago area.

There are also lots of factors taken into account for these rankings including number of teachers and how much money the school district spends on its students. Check out the full School Digger data to draw your own conclusions.
