Score Scale

Score You Need

70 percent

How It Is Calculated

IASSC scores the 100 graded multiple-choice and true or false questions and applies a single 70 percent threshold. Any additional non-graded questions on a form, up to 10 of them, do not count. There is no per-phase minimum and no compensatory weighting to work out, so 70 correct graded answers clears the exam regardless of which phases they came from.

IASSC does not publish a result turnaround time on its Green Belt certification page.

In raw terms: 70 of the 100 graded questions correct

  • Successful candidates receive a PDF certificate with a certification number, a PNG badge, and an entry in the Official IASSC Certification Register.
  • IASSC grants the right to use its certification marks and titles under the IASSC Marks Use Policy.
  • The recertification exam uses the same 70 percent threshold across 50 questions.
  • IASSC does not publish per-phase score reporting for the Green Belt exam.
  • Two forms of valid ID (one government-issued with photo)
  • Appointment confirmation email
