the ITAP. This initiative will use implementation science to adapt, implement, and evaluate the implementation of interventions that serve men with HIV who are not consistently engaged in care or experiencing barriers to staying in care This initiative directly aligns with Ryan White Program 2030 (RWP2030), which is a renewed vision for the Ryan White HIV/AIDS Program (RWHAP). Building on the foundation of the RWHAP and the Ending the HIV Epidemic in the U.S. initiative, the RWP2030 framework is designed to sustain high-quality care and treatment for people currently receiving services through the RWHAP while expanding efforts to identify and engage individuals with HIV who are undiagnosed or out-of-care. The funded Evaluation Provider (EP) will lead a multi-site evaluation of the project and will provide evaluation-specific technical assistance (TA) to the implementation sites. The evaluation activities that the EP will conduct will draw from frameworks and approaches developed in the field of implementation science, including HAB"s Implementation Science Framework. The initiative emphasizes: 1) rapid adaptation, implementation, and evaluation; 2) implementation at a broad scale to produce generalizable findings; 3) public release of dissemination products based on human-centered design and adult learning principles, which foregrounds sustainability, rapid dissemination of findings, and replication of best practices.
