OGB-001 is one of the cheaper Open Group exams: a USD $325 booking fee buys one 30-question, 45-minute attempt, and 18 correct answers earn the TOGAF Business Architecture Level 1 credential. It is still sold today, but a newer 10th Edition exam, OGBA-101, now sits beside it at a higher price. This guide weighs the money against what you get back, then covers the syllabus and how long to study.

People who type "OGB test" into a search box usually want three things settled before they spend anything: whether the exam still exists, what the total bill really is, and whether a Level 1 badge changes anything at work. The sections below answer those in that order, using the figures The Open Group publishes. Where a figure comes from a particular Open Group document, the text says which one, so you can check it yourself before you pay.
Is OGB-001 still on sale, and how does it sit beside OGBA-101?
Yes. The Open Group's TOGAF examinations datasheet, whose footer carries a 2023-2025 copyright, still lists the TOGAF Business Architecture Part 1 exam under the code OGB-001, in English, based on the TOGAF Standard, Version 9.2. The Open Group's retail exam fee schedule, applicable from 1 February 2026 with corrections applied on 12 February 2026, still prices it. I read both documents in October 2026, and neither marks the exam as withdrawn.
