Common Questions and Answers about ISA Certification

Is there a practice exam available?

There are no practice exams available at this time. To help you study, we do offer exam outlines and suggested study materials. Both of these resources will provide details about the content of the exams.

Does ISA or my local ISA chapter offer any prep classes to help me study for the ISA Certified Arborist® exam?

Your local ISA chapter may have prep classes or trainings available prior to the exam. You will need to contact your local ISA chapter directly for more information about availability and cost.

If a preparation class is not offered in your area or during the timeframe that you need one, ISA offers study materials that you may purchase to help prepare for the exam as a self-study option.

How do I submit my exam application?

I did not receive a confirmation e-mail from ISA after I submitted my certification application online. Did it go through?

After submitting your online application, you will receive an e-mail confirming that your application has been received. This e-mail is sent to the e-mail address provided on your application. If you do not receive an e-mail after you submit your application online, contact the ISA Certification Department at isa@isa-arbor.com and they will verify if your application was successfully received.

What are the costs involved in taking the ISA Certification Exam?

The cost of the ISA Certification exam depends on which exam you are taking and whether or not you are a member of ISA and your local chapter. Please refer to the application handbook for the exam fees.

When is the next exam date in my area?

Go to the Exam Dates and Locations page to determine upcoming paper-based exams in your local area. If no paper-based exams are offered in your area, you may choose to take a computer-based exam at a Pearson VUE testing facility.

Can I take the ISA Certification exam at a location and time that is convenient for me through computer-based testing?

Yes, all certification exams are available as computer-based exams. Visit the Pearson VUE site to learn more about testing locations in your area.

Is the application available in Spanish for any of the exams?

I'm scheduled to take an exam but can't make it. Can I reschedule?

WHEN CAN I EXPECT MY EXAM RESULTS?

WHAT SCORE DO I NEED TO ACHIEVE TO PASS THE CERTIFICATION EXAMS?

WHY DON’T I GET THE SAME OVERALL SCORE WHEN I ADD UP ALL OF THE AREAS OF KNOWLEDGE 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 areas of knowledge.

IS IT POSSIBLE TO SEE THE QUESTIONS THAT I MISSED?

WHAT CAN I DO IF I DO NOT RECEIVE A PASSING SCORE THE FIRST TIME?

WHAT ARE THE COSTS INVOLVED IN RETAKING THE ISA CERTIFICATION EXAM?

My results were close to the passing grade, can I have my exam hand graded to ensure the score is correct?
