Old School is a clearinghouse of free and carefully vetted resources to educate people about ageism and help dismantle it. The site contains blogs, books, articles, videos, speakers, and other tools (workshops, handouts, curricula etc.) that are accessible to the general public. The goal of the Old School Clearinghouse is to inform and help catalyze a movement to make ageism as unacceptable as any other kind of prejudice. We created it because movements need tools, best practices, and ways to share them. To that end, and because this work can be hard and lonely, in 2021 we began hosting quarterly, virtual Movement-Builders Convenings for people who identify as pro-aging/ anti-ageism advocates. A related Google Group enables participants to learn more about and support each other's work.
