How do I become a licensed arborist?

In order to become a licensed arborist, an individual must apply to take an exam (.pdf) administered by the Division, pass the exam and must demonstrate proof of adequate insurance (.pdf).

Information on Taking the Arborist Licensing Exam.

Arborists holding a valid arborist license from another state and arborists that are ISA certified do not need to take the test, but must apply for a license (.pdf) if they wish to work in Maine.

Individuals with no experience in arboriculture can obtain an apprentice license (.pdf) without taking an exam, providing they work under the direct supervision of a licensed arborist.
