Courses vary in length from a few weeks to two years. There are no formal academic requirements for entry into RNC, but potential students are invited to attend an assessment at the college before being offered a place to determine the level of support they will need during their studies. The assessment typically includes an evaluation of a person's level of vision, their mobility and independence skills, any residential support they may require, basic literacy and numeracy skills tests, and an interview with the leader of the course they wish to take.
