What you'll need
Tree Nerd Academy account
6+ hours of video, 4,500+ practice questions, mock exams, AI tutor, and the daily progress tracker.
60–90 minutes per day
Set a fixed time block. The plan only works if you show up consistently. Skipping days = re-baseline at the next mock exam.
The official ISA textbook
The Arborists' Certification Study Guide (ISA, latest edition) is the source of truth. We recommend reading the chapter that matches each day's lesson — pair it with our videos and you'll lock the material in faster.
The official ISA textbook is sold separately on isa-arbor.com. We don't resell it — but our course content is built to complement it chapter by chapter.
