CIoTSP Pass Rate 2026: What the Data Shows

What We Can and Cannot Say About the CIoTSP Pass Rate

Search for the pass rate of the Certified Internet of Things Security Practitioner exam and you will find confident-sounding numbers on forums, vendor pages, and study sites. Treat nearly all of them with suspicion. CertNexus, the body behind the CIoTSP credential and its ITS-110 exam, does not feature a public pass-rate statistic on its official exam page. That means a figure like "78% of candidates pass" has no verifiable source we can point to, and we are not going to invent one here.

What we can do is something more useful: lay out the verifiable structural facts about the exam, explain what they imply about difficulty, and show where candidates realistically gain or lose points. If you want the broader difficulty picture alongside this, our companion piece How Hard Is the CIoTSP Exam? Complete Difficulty Guide 2026 covers the subjective side of the experience.

Why CertNexus Does Not Headline a Pass Percentage

Many certification bodies, particularly those that run vendor-neutral credentials, decline to publish aggregate pass rates. There are sensible reasons. Pass rates mix together first-time and repeat candidates, prepared and unprepared candidates, and multiple exam forms with slightly different cut scores. A single percentage hides all of that variation and can mislead more than it informs.

For ITS-110 specifically, there is an additional wrinkle: the official page indicates a passing score of 60% or 61% depending on the form, while the older blueprint document states 60%. When the cut score itself varies by form, an aggregate pass rate would blend results across exams that are not strictly identical in difficulty. You can read more on how those thresholds work in CIoTSP Passing Score 2026: Exactly What You Need to Pass.

What a "pass rate" would even mean here

• Population effects: The exam has no formal education, experience, training-hour, reference, or prior-certification prerequisites, so the candidate pool is unusually heterogeneous.
• Form effects: Multiple forms with a 60% or 61% threshold mean the effective bar shifts slightly.
• Attempt effects: The free same-version retake means some candidates are counted twice, which distorts any naive calculation.

The Cut Score: What the Exam Actually Measures

With 100 questions and a passing score of 60% or 61%, you are looking at needing roughly 60 or 61 correct responses if every question carries equal weight. CertNexus does not state a scaled-score methodology on the pages we reviewed, so treat that arithmetic as a planning heuristic rather than a guarantee.

The more important point is what a 60-ish percent bar signals. It is not an elite-gatekeeping threshold. It rewards broad, reliable competence across all seven domains rather than mastery of a narrow slice. A candidate who knows one or two domains cold but ignores the rest is exposed, because the blueprint distributes weight across seven areas.

Exam Format and Time Pressure on ITS-110

Time on ITS-110 is generous but not unlimited. After subtracting the five-minute candidate agreement and five-minute tutorial, you have about 110 minutes for 100 questions, a bit over a minute per item. For straightforward recall questions that is ample. The pressure builds on multiple-response items, where you must identify every correct option rather than a single best answer, and on scenario-style questions that require you to reason about an IoT deployment before choosing a control.

The multiple-response trap

Multiple-response questions are where partially correct knowledge hurts. Knowing that "encryption is important" is not enough; you need to distinguish, for example, which controls protect data at rest versus in transit, or which authentication mechanisms suit constrained devices. Candidates who skim and pick the first plausible options tend to bleed points on these items.

Closed-book and proctoring conditions

The exam is closed book, and we could not verify any permission for an external calculator. If you test through OnVUE, expect the standard online-proctoring requirements: a clean workspace, identity verification, and a stable connection. Technical or environmental issues can raise stress even when your knowledge is solid, so do a system check well before test day.

Where Candidates Lose Points: Domain by Domain

Since no official pass-rate breakdown by domain exists, the best way to estimate risk is to look at blueprint weight and conceptual density. The following is our analytical judgment, not published CertNexus data. For the full blueprint, see CIoTSP Exam Domains 2026: Complete Guide to All 7 Content Areas.

Who Sits for ITS-110 and How That Shapes Outcomes

Because there are no formal education, experience, training-hours, reference, or prior-certification prerequisites, ITS-110 draws a mixed audience. IoT/security familiarity is recommended but not enforced. See CIoTSP Requirements 2026: Eligibility, Prerequisites & How to Qualify for the full eligibility picture.

In practice, you can expect several broad candidate profiles:

• Network or systems security professionals adding IoT context. They usually find Domains 2, 3, and 4 familiar and need to invest in IoT-specific portal and firmware concepts.
• Embedded and firmware engineers moving toward security. They tend to be strong on Domains 6 and 7 but may be weaker on portals, privacy, and accounting concepts.
• IT generalists and analysts seeking an entry point into IoT security. They benefit most from structured preparation because the vocabulary is new.
• Product, compliance, and privacy staff who need to understand device risk. Domain 5 may come easily while technical domains require more work.

This spread is exactly why a single pass-rate number would be unreliable: the same exam serves very different starting points. Employers that value the credential tend to sit in IoT product development, industrial and building-automation environments, and security consulting; for a fuller view see CIoTSP Jobs and Is the CIoTSP Certification Worth It? Complete ROI Analysis 2026.

Retake Policy and Voucher Economics

The current voucher is $367.50 USD, and current policy includes one free same-version retake within the voucher validity period, normally 18 months. That changes the risk calculation considerably. A first attempt that falls short is not a second full payment; it is a diagnostic with a built-in second chance, provided you stay within the validity window and sit the same exam version.

Validity and renewal

The credential is valid for three years. The verified renewal route is taking the latest-version exam before expiration. CIoTSP was not on the reviewed CertNexus continuing-education eligible list, so do not assume a CE credit route or a CE-only renewal fee applies to this certification. Plan on a fresh exam attempt when your three years approach their end.

A Domain-Weighted Preparation Sequence

Rather than a generic weekly template, here is a sequence tied to blueprint weight and how the domains build on each other. Adjust the length to your background; a security veteran might compress this, while a newcomer should stretch it. Our fuller plan lives in the CIoTSP Study Guide 2026: How to Pass on Your First Attempt.

Because the exam is closed book and mixes single-answer and multiple-response items, practice under realistic conditions. Timed sets, with attention to multiple-response questions, are far more valuable than rereading notes. You can run exam-style drills on our CIoTSP practice test platform, and keep the CIoTSP Cheat Sheet 2026: One-Page Review of Must-Know Facts handy for final review.

Reading practice results honestly

Because no official pass-rate data exists, your own practice scores are your best signal. Aim to score comfortably above the 60-61% threshold across all seven domains, not just in aggregate. A strong total that hides a weak Domain 1 is a warning sign given its 29% weight.
