I’m often asked why a particular program did not meet Blueprints criteria. Most programs fail to receive Blueprints certification because their scientific evaluations have major limitations.
These limitations are such that apparently positive results could emerge not from participation in the program but from design problems in the evaluation. The most obvious problems are not having a control group (in which participants are compared to nonparticipants) or not assigning participants to the intervention and control groups randomly.
Keep reading to discover some of the most common methodological problems.
