What is the Passing Score for ISTQB Certification Exams? The passing score for any ISTQB certification exam is 65% or greater. For the ISTQB Foundation Level exam, this means that you must answer at least 26 of the 40 questions correctly to pass. Note: Other ISTQB exams may have a different number of questions, and/or the questions may vary in how many points they are worth, so answering 26 or more questions correctly may not guarantee passing other ISTQB exams. ISTQB’s standard of scoring 65% or higher is the key measure for passing an exam. See the number of questions and points on each ISTQB exam by syllabus chapter.
