The document discusses a policy decision model to assess the policy environment for HIV services for key populations such as men who have sex with men, transgender people, and sex workers. The model conducts an in-depth analysis of over 1,100 policy points across health, law, and other sectors to identify gaps and challenges. It layers this analysis on human rights frameworks to inform advocacy and service improvements. The model also includes methodology, required technical skills, and provides an example output analyzing Burkina Faso's policy environment.
