Throughout the COVID-19 pandemic there has been a corner of society where the spotlight has not fallen -- the black hole of prisons, confining predominantly poor, minoritised and often younger adults. Globally, during the pandemic, people detained in prison have been locked away in solitary, or near solitary, confinement for up to 23-hours a day. In the UK, this meant choosing between fresh air, exercise or a phone call to loved ones each day. There has been little mention of education. Those in custody endured over a year locked in a cell without access to basic education let alone Higher Education (HE). In examining the state's responsibility to provide "education for all", we demonstrate, through our collective participation in the Inside-Out Prison Exchange Programme, the value and importance of prison education beyond the current focus on risk, responsibility and recidivism. We evidence the transformative and humanising potential of HE in prison through three key elements -- the space and learning environment; the role of voice, recognition and agency; and the power of disruptive and transgressive teaching practice. We shine a light on education in prison during the COVID-19 pandemic. The impacts of COVID-19 expose new and deeper forms of structural disadvantage that shape the educational experiences and journeys of people in custody. We consider how we can expedite "education as the practice of freedom" for those who are incarcerated during and beyond the pandemic. We conclude by reimagining HE in UK prisons, reflecting upon alternative, more positive, approaches to prison education.
