All our L.E.A.D. programs are accredited, which apply evidence-based best practices and discuss their effectiveness, teach strategies for building resiliency, and teach life skills and prevention strategies.   Each Too Good program received a third-party researcher evaluation where researchers used randomized treatment-control group designs (pre-test/post-test, 20 week post-test, or one year follow-up).  These researchers examined pre-test, equivalence between treatment and control groups, potential bias of loss of student data over time; quality of program implementation; and estimates of reliability and validity of assessment tools.
