About PPN Programs
Proven and Promising Programs
Programs are generally assigned either a Proven or a Promising rating, depending on whether they have met certain evidence criteria.
Other Reviewed Programs
Some programs are identified as Other Reviewed Programs. These programs have not undergone a full review by PPN, but evidence of their effectiveness has been reviewed by one or more credible organizations that apply similar evidence criteria.
