In addition to the national certification, some states require the CLS practitioner to obtain a license, usually requiring one of the national certifications and/or a state licensing test. The following list is provided as an advisory to CLS students, but is not guaranteed to be complete or current. The interested student should contact the state of interest for more details about any requirements for working as a CLS in that state. Texas, at this time, does not require a license.
