Technician Certification with Other States
Wisconsin will register certified technicians that passed exams from Michigan, Minnesota, Ohio and Nebraska within the past 5 years. Service company technicians need to complete and return the Service Company Technician Certification form. This no fee form is available here. Applicants must include proof of registration or a copy of test results if tested outside of Wisconsin.
The states of Michigan, Minnesota, Ohio and Nebraska have us administer an exam on their state laws in addition to the exams on HB 44. You will need to contact these states prior to submitting a Service Company Technician Exam application to DATCP and obtain the following:
- Test preparation materials
- Complete any service company registration requirements for that state(s)
