According to LegalMatch, the legal age of consent in the state of Illinois is 17. However, it is illegal for adults over 18 who are in a position of authority over minors, such as teachers or coaches, to engage in sexual contact with anyone under 18.
According to Steven C. Haney, Illinois does not have a "Romeo and Juliet" law allowing people over the age of majority to engage in sex with minors within a certain age difference. This means that anyone over the age of 17 can be charged with statutory rape for having sexual contact with someone under 17.
