Update this listingTell me if Illinois starts a program
Illinois has no program that pays private school tuition today. It could still start one, or opt in to the federal scholarship tax credit that starts in 2027. Leave your email and we will write once, with the official link, if Illinois starts a program or scholarships under the federal credit open. That is the only email you get.
One email if that happens. No calls, no sharing your details.
