As individuals move along their career progression, their competencies will grow and develop. At each key milestone, the individual will have developed or gained a different level of competency that can be recognized, thus providing a clear differentiation between certification levels. The certification level encourages a BA professional to seek growth through specific learning and development to support them in achieving the desired level. IIBA certification programs will assess and measure an individual's competencies at any given level thus ensuring the BA professional and employer knows what is expected at each level.
