ISA Certified Arborist Exam Cost, Scheduling, and Registration

breakdown of ISA exam fees for members vs non-members, how to schedule with Pearson VUE, and tips for avoiding rescheduling fees.

Getting your ISA credentials involves some logistics and upfront costs. Unlike some other trades where you just show up and test, the ISA has a strict application and vetting process.

Here is everything you need to know about the costs and how to get your date on the calendar.

Exam Costs: Member vs. Non-Member

The ISA incentivizes membership.

  • ISA Member Fee: ~$170 USD.
  • Non-Member Fee: ~$280 USD.
  • ISA Membership Cost: Typically ~$150-$170/year (varies by chapter).
  • The Math: If you are planning to buy the study guide ($90 vs $130) and take the exam, membership usually pays for itself immediately. Plus, you get access to CEUs later.

Testing Centers vs. Paper Exams

You have two options for taking the test:

  1. Computer-Based Testing (Pearson VUE):
    • Pros: Schedule any day/time that works for you. Instant results. Quiet environment.
    • Cons: $125 administrative fee (on top of exam fee).
  2. Paper-Based Testing (Chapter Exams):
    • Pros: No extra admin fee.
    • Cons: Fixed dates (usually on weekends). Results take 4-6 weeks to arrive by mail.

The 90-Day Window

Once your application is approved, you are given a 90-day authorization window.

  • You must take the exam within this window.
  • If you fail to schedule or show up, you forfeit your fee.
  • Extension: You can usually purchase a 90-day extension for ~$50 if life happens.

Rescheduling Rules

If you are taking the computer-based exam with Pearson VUE:

  • > 24-48 hours notice: You can usually reschedule for free or a small fee.
  • < 24 hours notice: You forfeit the exam fee.
  • Tip: Do not wait until the night before to check your location.

Recertification Costs

Passing is just the start. To keep your credential, you must:

  • Pay a recertification fee every 3 years.
  • Earn 30 Continuing Education Units (CEUs).
  • If you don't pay or don't earn the CEUs, you have to retake the exam.

Summary Checklist

  1. Become an ISA Member (Recommended).
  2. Apply for Eligibility (Wait 1-2 weeks for approval).
  3. Receive Authorization Letter.
  4. Create Pearson VUE account (if taking CBT).
  5. Schedule Exam.
  6. Pass.
