High School

High school biology classes can provide you with a solid background to be a successful arborist. An interest in gardening, conservation, or the outdoors is also helpful.

Postsecondary Training

You will need at least an associate degree to work as an arborist. Take classes in botany, chemistry, horticulture, and plant pathology. Many colleges and universities offer programs in arboriculture and other related fields such as landscape design, nursery stock production, or grounds and turf maintenance. Entry-level positions such as assistants and helpers do not require a college degree for employment. Advanced education, however, is highly desired if you plan to make this field your career. Additionally, most companies provide on-the-job training that lasts from one to three months.

Other Education or Training

Keeping up with industry developments is key to success as an arborist. Professional associations often provide continuing education (CE) opportunities. The International Society of Arboriculture, for example, offers workshops, symposia, and conferences on topics such as tree risk assessment, tree problem diagnostics, advanced tree biology, and structural pruning. The Society of Municipal Arborists and Tree Care Industry Association also provide a variety of CE opportunities. Contact these organizations for more information.

Certification or Licensing

Today's savvy consumers specifically look for certified or licensed arborists when it comes to caring for their trees and other precious landscaping plants. Most arborists are certified or licensed. Certification, given by the International Society of Arboriculture after completion of required training and education, is considered by many as a measure of an arborist's skill and experience in the industry. Available certifications include certified arborist, certified arborist utility specialist, certified arborist municipal specialist, certified tree worker climber specialist, certified tree worker aerial lift specialist, and board certified master arborist. Arborists need to apply for recertification every three years and must complete continuing education classes and seminars.

Licensure ensures an arborist meets the state's regulations for working with pesticides and herbicides. Check with your local government—not all states require arborists to be licensed.

No experience is needed to work as an arborist, but those with prior work experience will increase their chances of landing a job, getting promoted, and possibly earning higher pay.

Aspiring arborists need "green thumbs" and a passion for caring for trees and shrubs. They need to be physically fit and have good manual dexterity because they will frequently reach, bend, and climb while performing their duties. Other important traits include strong communication skills, the ability to work well with others, and a willingness to continue to learn throughout your career.
