Programs For Inmates

As an intake facility, the programs at Byrd Unit are extremely limited. However, they do participate in the GO KIDS Initiative.

The GO KIDS Initiative

GO KIDS touches offenders through programs geared towards strengthening the parent-child relationship, as well as their families and children. For the latter, GO KIDS provides resources that offer basic fundamental elements such as mentoring and encouraging parent/child relationships, as well as support in the areas of health, legal counsel, and employment. 

Parenting training, stress management training, social, and mental health services, home-based interventions, and advocacy with schools are also services that can be obtained. As positive youth development is a key factor in breaking the cycle of incarceration, many of the offered programs are geared toward creating for children a sense of personal safety, a sense of belonging, self-worth and responsibility, as well as support and guidance from caring adults.

For the offenders, GO KIDS focuses on programs that provide effective parenting education and training, as well as offer avenues to facilitate child/parent connections.
