TAQA is an unofficial acronym which stands for Training, Assessment and Quality Assurance.
There is no TAQA qualification, just the the 3 separate qualifications mentioned above.
Training = 'Award in Education and Training' or 'Train The Trainer'
(it used to be PTTLS but that has gone now)
Assessing = RQFA (CAVA) - We deliver this course
Quality Assurance = IQA - We deliver this course
