The GNTA requires that all TVET instructors complete an instructor training programme that focuses on building competencies required for planning and delivery of competency-based education and training (CBET) programmes. The Quality Assurance Department of the NTA conducts CBET Instructor Training for TVET instructors. This training is done over a period of six days (usually, 3 days per week for 2 weeks). To be eligible for certification, participants must attend the training workshop, complete a practicum and submit a portfolio. Participants must have certification in the occupational area in which they intend to conduct training.
