The Pretest:

This is the longest part of the exam and will mainly review the consent form and establish that the subject is not a health risk and the subject is a good candidate to receive the exam. The question formulation is then administered. On average three questions can be asked of the subject, this is done to maintain a 90 to 95% accuracy rate. 

The recording of the charts:

All the equipment from the instrument is attached to the subject and a final set of instructions are reviewed. The examiner then records three charts on the developed questions. 

Analyze the charts:

This process many times will not be done at the site of the exam. Because of multiple charts and questions the examiner will review the charts within a 24 hour period and then report back to the client.
