Score You Need

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.
