The HMSU at Prince Albert is one of two built by the Correctional Service of Canada to contain approximately 80 of the country's "most dangerous inmates on a transitional basis" and at great expense. A number of the evaluation's recommendations referred to in this paper are instructive for further program development, but educational television in the HMSU has already established itself as a genuine approach to fostering some degree of communicative competence within a very tense, artificial environment. While significant aspects of the evaluation process itself are addressed, a critical commentary is also included on the concept of regulated solitary confinement and the ways that educational television (ETV), despite clear-cut benefits, could be effectively deployed to reinforce the most harmful consequences of such confinement. This has implications, too, for the deployment of ETV to serve "special groups" on the outside. (Author abstract)
