There are several ways, but IL is not a ELSES state, so the wait is usually a little longer than some.
There is always the snail mail method.
https://www.idfpr.com/dpr/licenselookup/default.asp the last license # issued was 062061168, so if you find a lot more license numbers after that the state has most likely issued the new # to those that passed. This is how I found out a couple yrs ago. The actual license showed up a week later then about 2 weeks later a letter from CTS came.
Apparently in more recent time, CTS now offers an online look up too to see if you pass or fail.
