National Resource Center for Osher Lifelong Learning Institutes

Chicago's educational research institute list runs 29 entries, too many to scroll top to bottom and expect much. Zip code narrows it faster: 60637 holds 7 of the listings, while 60604 and 60608 have just one each. None of the 29 show a verified badge yet, and none carry a Sponsored tag either, since paid placement hasn't switched on for this category in Chicago. So the order you see is entry order, not a ranking. Most listings do have contact info, 27 with a phone number and 26 with a website, so calling ahead or checking the site is usually an option.

If you run one of these institutes and the phone or website field is blank, claim the listing and add it yourself. That matters most in the single-entry zips like 60604 and 60608, where there's no second nearby name to fall back on. Start with 60637 if location isn't fixed, since it has more entries to compare side by side.
