Grinnell Hall Senior Center in Beloit Manager Debbie Kraus thanks the committee who’s members put in more than 250 hours on the process. Kraus says the WASC accreditation process helps bring clarity to Grinnell Hall operations, provides direction for current and future services and programs, identifies areas to be expanded or strengthened, and promotes efficiency and organization. Grinnell earned its initial accreditation in 2012.
