The IOS-158 exam contains Approximately 40–45 questions and gives you 120 minutes to complete them. That works out to a brisk pace, so you cannot afford to stall on a single tricky item — flag it, move on, and circle back if time allows. Before exam day, run at least two timed mock sessions with the Exams4sures desktop or online test engine; practicing against a real clock turns the official time limit into a comfortable rhythm instead of a source of panic.

The IOS-158 exam (full name: Infor Certified OS Associate) is a Infor certification exam that leads to the Infor OS credential, positioned at the Associate level. It validates the skills Infor expects from professionals working with its technologies, and passing it is the key step toward getting certified. It also sits within a broader certification path that includes Infor Certified OS Professional, Infor Certified OS Expert.

The Infor Certified OS Associate exam is organized into 5 domains. The main areas include Using Infor OS, User Management, and Setup & Configuration. Scroll up to the exam syllabus section on this page for the complete topic-by-topic outline.

No formal prerequisites; familiarity with Infor OS concepts and basic administration is recommended.

Eligibility requirements can change, so before you register, confirm the latest criteria on the official Infor exam page.

To pass the IOS-158 exam you need a score of Varies (set by Infor, typically around 70%), and the official registration fee is Varies by region (check Infor Certification portal). Keep in mind that a failed attempt comes at full price: retaking the exam means paying the entire fee again. A smart way to protect that investment is to self-test first — work through the 45 practice questions at Exams4sures until your timed scores sit comfortably above the passing line before you book a seat.
