Registration for the Infor Certified OS Associate goes through the official channels listed here:

• Infor Certification Portal

As for the format, the IOS-158 exam is delivered Online proctored or authorized test center — pick whichever fits your situation when you schedule.

The official Infor Certified OS Associate blueprint is divided into 5 domains, led by Infor OS Fundamentals & Architecture (25%), Document & Content Management (20%), and Workflow & Process Automation (10%). The full domain-by-domain breakdown is in the syllabus section above — that is the checklist your study plan should follow.

The passing score for the IOS-158 exam is 700/1000 or 70%, and registering officially costs $200–$250 USD. That fee buys exactly one attempt — if you fall short, the retake is charged in full again, no discount for a second try. The practical move is to measure yourself first: drill the 45 practice questions at ValidVCE under timed conditions until your mock scores clear the bar with room to spare, then book your seat.

You can. ValidVCE publishes a free PDF demo of the IOS-158 practice questions — download it, work through it, and decide on evidence rather than promises. Once you own the full product, 365 days of free updates are included, and an expired product can have its update service renewed at a 50% discount from your member zone.

The IOS-158 exam — officially the Infor Certified OS Associate — is how Infor verifies that you can apply its technologies in real working scenarios, and passing it earns you the Infor Certified OS Associate certification, a credential at the Associate level. Employers recognize it because it is vendor-issued and skills-based. Candidates often continue toward related credentials such as Infor Certified OS Professional once this one is in hand.

You will face 40–60 questions within 90 minutes on the IOS-158 exam. Do the math once and the lesson is clear: dwell too long on a hard item and the clock eats your easy points later. The fix is rehearsal, not luck — take full-length timed mocks in the ValidVCE desktop or online test engine until pacing becomes automatic, and learn to flag a question, move on, and return with fresh eyes.
