Widespread implementation of PYD approaches in the juvenile justice system faces many challenges. Philosophically however, the PYD framework resembles the progressive era ideals that informed the creation of the first juvenile court. As Butts, Mayer and Ruther describe, "The concepts underlying PYD resemble those that led to the founding of the american juvenile justice system more than a century ago. [...] Organizers of the first juvenile courts saw the solution to delinquency in better schools, community organizations, public health measures, and family supports. They believed an improved social environmental would encourage youth to embrace pro-social norms."
