ISA Certified Arborist Test Preparation Course (Learn-to-Earn)
This course is offered twice a year and is entirely online, but is instructor-led so you have a chance to interact with an actual person for questions and explanations of the presented material. There is a live session each Saturday broadcast in real time. If you miss a live session, don’t worry, each one is recorded so you can view them any time.
This is a “learn to earn” course. The cumulative grade earned at the end of the course (between 0 and 100) is the amount of your refund. In other words, the harder you work the more money you earn to use toward taking your ISA exam. The primary text for this course is the Arborist’s Certification Study Guide by Sharon Lilly (2022 edition) which can be ordered directly from the ISA.
You’ll cover all ten ISA knowledge areas with clear, easy-to-follow live sessions, plus interactive tools like flashcards, crosswords, and quizzes to lock in key terms and concepts. Each module includes practice questions, and the final module delivers proven test-taking strategies along with a full-length practice exam that mirrors the actual ISA exam.
Passing the ISA Certified Arborist exam can be intimidating. Tall Tree Learning can help. After seven short weeks of intensive training you will enter the exam room with confidence knowing that when you leave you will be the next ISA Certified Arborist.
