While the former refers to the preparation or training programs occurring in the various colleges in a certain university to prepare doctors, teachers, engineers, accountants etc…, the latter refers to that type of training of taking place inservice. This type is, in most cases, related to enhancing professional development, and improving performance. Such training must be conducted with careful attention to the needs of learners, the context in which learners perform and current evidence about what makes training effective.
