how old do children have to be to drop out of school in illinois
Best Answer: You cannot drop out of high school in Illinois until you are 17. It has nothing to do with parental consent. Illinois law does not care. Also, if you drop out, if you have a driver's license, it will become void. You cannot take the GED until you are 18. You can drop out of high school in IL at age 16 if you have parental consent.
