The Programs We’ve Identified Are Linked Below

Programs identified as having the most credible evidence of effectiveness, based on careful review in consultation with outside experts, are categorized as “Top Tier” or “Near Top Tier” (see sidebar for definitions). The other listed programs have been found promising but not yet Top Tier or Near Top Tier due to study limitations (such as only short-term follow-up) that underscore the need for additional testing prior to larger-scale implementation. As a nonprofit philanthropic foundation, we receive no financial benefit from any program, enabling us to serve as an impartial reviewer of the evidence.

Top Tier Critical Time Intervention (A case management program to prevent recurrent homelessness in people with severe mental illness): Randomized controlled trials show a sizable decrease in rates and duration of homelessness.
