Housing First and harm reduction are highly effective strategies for ending homelessness among adults but are not fully embraced for youth - even though these strategies work well with a key approach to youth homelessness: Positive Youth Development. This workshop will provide a deeper understanding of all three approaches and how to make them the cornerstone of coordinated community responses to youth homelessness. We will also highlight the challenges of implementing effective Housing First for youth, including adultism, and best practices in overcoming those challenges.
