This document defines and compares different types of training provided in business studies including on-the-job training, off-the-job training, retraining, and apprenticeships. On-the-job training involves coaching and demonstrating tasks while employees remain at work, while off-the-job training removes employees from the workplace for classes, self-study, or sandwich courses. Retraining adapts employee skills to new technologies, practices, or safety requirements. Apprenticeships formally commit employers to train young employees through work experience leading to an industry-recognized qualification.
