Eligible applicants are limited to states (including territories), units of local government (including federally recognized tribal governments, as determined by the Secretary of the Interior), nonprofit and for-profit organizations (including tribal nonprofit and for-profit organizations), and institutions of higher education (including tribal institutions of higher education). For-profit organizations must agree to forgo any profit or management fee. OJJDP welcomes joint applications from two or more eligible applicants; however, one applicant must be clearly indicated as the primary applicant (for correspondence, award, and management purposes) and the others indicated as co-applicants. The primary applicant for this solicitation must be the organization conducting and leading the mentoring evaluation or research. While the lead evaluator/primary applicant may partner with additional research and program sites through subrecipient relationships, the primary applicant must clearly be the entity with primary responsibility for conducting the research or evaluation.
