Developing a formal assessment is not as easy as writing items and releasing an exam to an audience. Instead, it is a painstaking process that must be carefully executed. Item-writing is only one step in the process of developing a valid exam to be used for professional decisions. However, it can be regarded as the most critical.

Typically, the development of a high-stakes exam requires 6-12 months to complete. This process requires input from many professionals who have a high degree of understanding in the subject matter areas being assessed.

The above figure shows the eight-step process that forms the basis of a continuous improvement program for high-stakes exams. As evidenced in the illustration, the process is cyclical and some steps must be revisited more frequently than others. Certifying bodies should not consider any of these steps as optional.
