The aim of the present study was to examine inmates' educational motives. The participants were 467 inmates who attended education in Norwegian prisons. Three motive categories were identified: "To prepare for life upon release" (Factor 1), "social reasons and reasons unique to the prison context" (Factor 2), and "to acquire knowledge and skills" (Factor 3). Factor 1 explained more of the variance than the sum of the other factors, and educational level was not related to scores on this first factor. Inmates with long sentences were more likely than those with short sentences to start an education in prison to prepare for life upon release. Inmates with low education scored significantly higher on Factor 2 than those with high education, but significantly lower on Factor 3 than the latter group. (Contains 4 tables.)
