Exam Results

The following are common questions and answers about obtaining the results from your certification exam.

When can I expect my exam results?

Exam results take 4-6 weeks to be processed for paper and pencil exams. Once they are available, we will mail them to you via U.S. mail. Results will not be given via email, phone or FAX in an effort to maintain complete confidentiality.

If you take a computer-based exam, you will receive a copy of your results at the site before you leave. An official copy of your results will be mailed to you within 4-6 weeks.

What score do I need to achieve to pass the ISA Certified Arborist® exam?

You must earn a minimum overall score of 72 percent.

Why don’t I get the same overall score when I add up all of the domains and divide them?

The number of correct responses determines the overall score. Each of the domains are scored individually and since they do not have the same number of questions, you cannot add them all up and divide by the number of domains.

Is it possible to see the questions that I missed?

No, due to the confidentiality of the exam questions, it would compromise the integrity of the exam. To maintain exam security, we cannot release any of the exam questions.

What can I do if I do not receive a passing score the first time?

If you do not receive a passing score, you will be required to retake the full exam again. We recommend that you review your score sheet and determine further areas for studying.

How much does it cost me to retake the exam?
