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.
