CTS Certifications
A premier professional certification organization, the Certification Testing Service (CTS) offers top-notch certification programs. CTS’s certification programs are designed to help you establish professional credentials and to give you a means to validate your skills and knowledge. With CTS certification, you can be sure that you have met a high quality standard.

CTS certifications are administered globally and are not limited to a specific state or country. If you become certified in one state or country, your certification is still valid if you move to another geographic location.
CTS’s CTWS certification exam has no recommended texts for study as the knowledge over which you are tested is gained primarily from experience.
