Both promising and model programs meet basic Blueprints standards, but model programs meet additional requirements. Promising programs must have evidence from one high-quality experimental or two high-quality quasi-experimental designs, clear findings of positive impact, carefully defined goals, and sufficient resources to help users. Model programs must have evidence from two high-quality experimental or one experimental and one quasi-experimental design of high quality, and in addition to the above criteria (positive impact, defined goals, dissemination capacity), have a sustained impact at least 12 months after the intervention ends. Model programs which have conducted a high-quality “independent” replication have been labeled as Model Plus. Model and Model-Plus programs are deemed ready for widespread use.
