Why is the same syllabus used for both the ISEB Foundation and ISTQB Foundation exams?
The BCS decided to align the ISEB Foundation exam requirements with the ISTQB Foundation exam requirements, as both certifications are very similar in scope. The only material difference is that the ISEB Foundation is primarily a UK-specific certification, whereas the ISTQB Foundation is its international equivalent. However, the content is essentially the same in each, so the logical decision was made to combine the two. Now that both syllabi are aligned, passing one of the Foundation exams provides dual-accreditation in both. Please read this article for more detailed information.
