Wyo. Stat. Ann. § 33-42-114

If a person holding a license entitling him to drill water wells or install pumping equipment in another state applies for a Wyoming water well drilling contractor's or water well pump installation contractor's license, if the other state offers reciprocity, and if the board determines the standards and requirements of the state in which the applicant is licensed are equal to or exceed the standards or requirements of this act, the board may waive the examination requirements except the applicant shall successfully complete an examination based on Wyoming statutes and rules relating to the drilling of water wells or installation of pump equipment. The applicant shall also pay all applicable fees.
