Look up state tree-expert/arborist licensing requirements (e.g., NJ, CT, MD)

Steps

1. Identify whether the target state runs its own tree-expert/arborist licensing program beyond ISA certification — New Jersey (Licensed Tree Expert/Tree Care Operator), Connecticut (DEEP Arborist license), and Maryland (DNR Licensed Tree Expert) each administer independent state programs.
2. For New Jersey, verify via the NJ Board of Tree Experts (njtreeexperts.org / nj.gov/njbte); LTEs generally need a qualifying degree or equivalent experience, exam passage, and 32 continuing-education credits every two years.
3. For Connecticut, use CT DEEP's license lookup tool under the 'Pesticide Commercial Supervisor' category, subclass 3D Arborist; licensure requires passing a written exam plus tree-identification and practical/oral exams.
4. For Maryland, use the DNR 'Find a Licensed Tree Expert' lookup by company, county, or name; licensees need qualifying education/experience, an exam, proof of liability insurance, and 8 continuing-education credits every two years.
5. Confirm current license status directly on the relevant state board's public lookup tool rather than relying on a contractor's self-reported license number.
