Certification Management Services

High Quality &

Efficient Solutions

The CMS history is filled with extensive, successful testing experience.

Scott and Kim Thayn, long time testing and assessment professionals well versed and trained in psychometrics, business development, program management, and client management, decided in June 2006 that it was time to offer testing services according to their own vision. Hence, CMS opened its doors.

CMS has been busy ever since that decisive opening day. CMS clients span a wide array of industries, including IT, corporate, healthcare, academic, professional association and government industries.

CMS focuses its services, tools, and solutions to provide its clients with the highest quality products in the most efficient manner for the greatest value. CMS’s founders and its other employees have long standing histories of great service relationships. This has enabled CMS to understand client needs and to remain responsive and nimble to solutions that are meaningful to its client.
