Training Units are a type of educational program that is designed to help employees learn the skills and knowledge necessary to perform their job. The two main components of Training Units are Reps (4 letters) and LESSONS (7 letters). Reps stands for repetitions, which are activities that are repeated multiple times in order to reinforce learning. LESSONS are more formalized instruction that is designed to teach specific skills or knowledge. Training Units are often used in corporate settings to ensure that employees have the necessary skills and knowledge to do their job effectively.
