This article briefly compares the prison system in the United States with progressive correctional systems in the world, before pivoting to discuss the lessons learned from the author's development of the Prison Education Project (PEP). PEP has expanded educational opportunities for inmates in 12 Californian correctional facilities. With the assistance of 800 university student and faculty volunteers, PEP has serviced approximately 5,000 inmates in these facilities since 2011. By providing academic, life skills and career development programming, PEP aims to educate, empower and transform the lives of incarcerated individuals. This article is a summary of the development of PEP, examining programme outcomes and highlighting implementation, fundraising and branding strategies. The robust spirit of volunteerism is also a central component of the discussion, with the phenomenon of "reciprocal reflex" at the heart of the PEP volunteer experience. This reflex ignites the passion and gratitude of both volunteers and inmates. The volunteers learn just as much as they teach, and the inmates teach just as much as they learn. The fact that each group shows deep gratitude to the other for the learning experience creates an exciting symbiotic loop and an "esprit de corps" which inspires and empowers all involved. The "reciprocal reflex" leads to lifelong learning. This article captures the intricate dynamics of how PEP has evolved into the largest volunteer-based prison education programme of its kind in the United States.
