Do you need a degree to be an arborist?
What government career pages and ISA say about degrees, college programs and other routes into arborist work in the United States, Canada, the United Kingdom and New Zealand.
Checked against the sources at the bottom of this page on October 9, 2026. Rules, fees and pay change: the source has the last word.
This page reports what the official source says. It is not legal advice: ask the office named here.
The official sources read for this page do not make a degree the single way in. Each country's page names a different mix of experience, college programs, apprenticeships and degrees, and the answer in the sources is not the same across them. This page sets them side by side. The route guides for each country are routes into tree work.
Country by country
| Country and source | What it says about education |
|---|---|
| United States, Bureau of Labor Statistics | Entry-level grounds maintenance jobs typically have no formal education requirements. Employers may prefer a high school diploma or equivalent, and studying arboriculture is helpful |
| United States, O*NET | Of respondents, 57 percent said a new tree trimmer or pruner needs less than a high school diploma, 37 percent a high school diploma or equivalent, and 4 percent some college without a degree |
| Canada, Job Bank | Completion of a two-to-three year college program in a subject such as arboriculture or horticulture is usually required. An apprenticeship program is also available |
| United Kingdom, National Careers Service | A foundation degree, higher national diploma or degree is one of four routes, alongside a college course, an apprenticeship and working towards the role |
| New Zealand, Tahatu | A qualification is needed: a Level 3 or Level 4 certificate. Degrees are not listed, and Level 5 and Level 6 arboriculture qualifications are listed as ones a person may need |
What ISA says
For the ISA Certified Arborist exam, the program guide counts a degree toward the experience requirement rather than requiring one. An associate degree of two years qualifies when it includes two or more arboriculture courses and is paired with two years of full-time field experience. A bachelor degree of four years qualifies with four or more such courses and one year of experience. The default is three years of full-time experience with no degree. The same guide accepts assessment-based certificate programs of 900 or 1,800 hours in combination with experience.
What the careers pages add
- The BLS handbook says professional certification is not required for grounds maintenance workers, though it shows competency to clients and employers.
- The National Careers Service gives entry requirements for each UK route. A degree needs 2 to 3 A levels or equivalent, a foundation degree or HND needs 1 or 2, and an intermediate apprenticeship needs some GCSEs usually including English and maths. Its arboricultural officer profile lists a nationally recognised qualification such as the Level 4 Certificate in Arboriculture, with related job experience, for direct application.
- Job Bank says trade certification for landscape horticulturists is available but voluntary in all provinces. The page also lists Arborist as a regulated title in Ontario and Manitoba. Quebec requires a qualification certificate for arboriculture work for an employer, according to the government of Quebec.
- Tahatu says no specific NCEA levels are usually needed for school students.
Where the sources stop
None of the pages gives a share of working arborists who hold a degree. The O*NET figures are survey answers about what a new hire needs, not a count of degrees held. For Australia, the national records list Certificate II and Certificate III qualifications, covered in how to become an arborist in Australia.
