The overall quality of the processes used to develop the certification tests and testing procedures is very high and represents "best practice" within certification industry standards. The procedures followed were clearly based on established standards for educational and psychological testing as set forth by the American Educational Research Association, American Psychological Association, and the National Council of Measurement in Education.
Substantial thought and resources were invested in the foundation of the certification system, i.e., the job analysis. The development of the content specifications based on the job analysis of information was focused on the primary purpose of certification-the protection of public health and safety. The procedures used for test item writing, content validation, setting pass/fail cut scores, and the development of the overall certification process represent a system explicitly designed to optimize fairness and accuracy in certification testing.
