## Prerequisites for ISA Certification
Before you can apply to take the ISA Certified Arborist exam, you must meet certain eligibility requirements. These requirements are designed to ensure that candidates have sufficient practical experience and/or education in arboriculture.
There are several pathways to eligibility, allowing individuals with diverse backgrounds to pursue certification:
* **Option 1: Three or More Years of Practical Arboricultural Experience:** This is the most common pathway. You must document at least three years of full-time experience working in arboriculture. This experience can include a variety of tasks such as pruning, tree planting, tree removal, diagnosis of tree problems, and other aspects of tree care.
* **Option 2: A Combination of Education and Experience:** You can combine formal education in a related field with practical experience. For example, a two-year degree in arboriculture, horticulture, forestry, or a related field, combined with one year of practical experience, may meet the eligibility requirements. Similarly, a four-year degree in a related field may significantly reduce the required experience.
* **Option 3: ISA Certified Tree Worker Climber Specialist Certification:** Holding a current ISA Certified Tree Worker Climber Specialist certification fulfills the experience requirement for the ISA Certified Arborist exam. This pathway is ideal for experienced tree climbers who wish to advance their careers.
* **Option 4: Qualifying Certification/Degree in a Related Field:** Holding certain qualifying certifications or degrees can also satisfy the eligibility requirements. Examples may include a degree in forestry, horticulture or a related field coupled with some years of experience.
**Detailed Breakdown of Experience:**
* **Full-time Employment:** The ISA generally defines full-time employment as working at least 30 hours per week.
* **Documenting Experience:** You will need to provide documentation of your experience, such as letters from employers, pay stubs, or other official records. The ISA may require verification of this information.
* **Relevance of Experience:** The experience must be directly related to arboriculture. General landscaping experience that does not involve specific tree care tasks may not be sufficient.
