I assume you want this because of uncertainty regarding the performance of Chicago schools. In my experience it is and has been common knowledge that Chicago schools perform poorly and have performed poorly for decades. I probably could spend more time giving more links, but I am not sure the time will be worth the effort. Regardless, of what follows it will either be "cherry picked", not all the data, or whatever they shot of the day will be.

The second is from the Chicago Tribune actually commenting on the discrepancy on how graduation rates are calculated but it shows Chicago with a HS graduation rate of between 52% and 54%
