Frequently Asked Questions
Is the ISA CA vocabulary game free?
Yes. The game is free to play with no sign-up. Signing in adds AI explanations for any term.
How do the ISA CA vocabulary games work?
There are 4 games built on 20 ISA CA terms. In Guess the Term, a clue describes one term and you have six tries to spell it, with green, yellow and gray letters showing how close you are. In Term Match, six terms appear as colored tiles; swap neighbors to line up three or more of the same term, and each match shows what the term means. In Term Pairs, twelve face-down cards hide six pairs of terms; flip two at a time to find each pair, and every pair you find shows what the term means. In Term Search, five terms hide in a grid of letters, reading across, down or diagonally; drag across a term to circle it, and each term you find shows what it means.
Where do the ISA CA terms come from?
OpenExamPrep researched each term from the International Society of Arboriculture (ISA) content outline and primary sources, listed under Sources on this page. The game is independent study material, not an official exam resource.
How hard is the ISA Certified Arborist exam?
The ISA Certified Arborist exam is moderately challenging because it covers 10 job-task-analysis domains across tree biology, identification, soils, planting, pruning, diagnosis, construction impacts, risk, safety, and urban forestry. ISA does not publish an aggregate pass rate. The best preparation is domain-weighted practice tied to real arboriculture decisions.
What is the passing score for the Certified Arborist exam?
The current passing score for the ISA Certified Arborist exam is 76%. ISA notes that the overall passing score can change when a job task analysis is performed, and domain averages are not the same as the overall score because the domains are weighted.
