2 Competency Based Skill Training Logbook Introduction Technical and Vocational Education and Training (TVET) Authority of Ministry of Education regulates and monitors the TVET programs conducted according to the National Competency Standards in the Maldives, to ensure that the competency based trainings delivered in the Maldives are quality assured. Thus, to ensure that the industry gets a skilled workforce, trained according to the industry needs, TVET Authority has developed Competency Based Skill Training (CBST) Logbooks for the National Competency Standards. The CBST Logbook is an assurance to all concerned parties that the training is being conducted with the relevant theory, activities and tasks for the occupation specified in the National Competency Standard. Hence the purposes of maintaining the CBST Logbook is to assess, monitor and improve competency, while giving the opportunity to work more on the needed areas of the occupation as the trainee proceeds with the training. Thus the CBST Logbook is an important component for the trainee to move forward in the training. As the CBST logbook specifies the tasks that an apprentice is to complete to be deemed competent according to the NCS, the Trainee must fill the necessary details of the CBST Logbook regularly, as he/she goes along the training. Similarly, the workplace supervisor has to sign in the log when the apprentice successfully completes each task. Additionally, through the CBST Logbook the external assessor who will be assessing the trainer when the training is complete can identify what are the tasks that the trainee completed under each unit, thus easing the assessment.
