Participation in Tier 2 was mandatory and could be enforced by sanctioning TANF benefits. Participants worked with Tier 2 case managers from local service providers, who had caseloads of 25 to 30 cases rather than the 75 to 100 cases of a typical Tier 1 case manager. Case managers performed detailed assessments of clients to identify the underlying challenges affecting them and their families and then referred clients to services that addressed those challenges. They also monitored participation, including through home visits.
