Off-the-job training (OTJ) is a mandatory component of apprenticeships in the UK that requires apprentices to spend a portion of their working hours on learning activities. Following a 2022 update, OTJ training must now average at least six hours per week over the duration of the apprenticeship, providing more flexibility than the previous 20% rule. OTJ training can include classroom sessions, online learning, workshops, or practical training, all aimed at developing the skills, knowledge, and behaviours needed for the apprenticeship.
