CHSO Passing Score 2026: Exactly What You Need to Pass

The 70% Rule: What the Passing Criterion Actually Says

If you are searching for the Certified Healthcare Security Officer passing score, the answer from the published official sources is simple: the passing criterion is 70%. The Certified Healthcare Security Officer credential is offered by the International Association for Healthcare Security and Safety (IAHSS) through the IAHSS Academy, and the Basic certification exam is built on the current Basic eLearning version 1.2, which launched on September 8, 2025.

That 70% figure is the single most useful number a candidate can hold onto. It is the threshold you are aiming past, not a target to scrape. Everything else in this article is about what surrounds that number: how the exam is delivered, what is and is not publicly known about how it is scored, and how to build enough margin that a handful of difficult questions does not decide your outcome.

For a broader look at how demanding the credential is in practice, see our guide on how hard the CHSO exam is. For background on what the credential represents, start with what CHSO certification is.

What the Public Record Does Not Tell You

Good preparation depends on knowing what is verified and what is not. Several details that candidates often assume are simply not disclosed in the public official materials reviewed for this article:

• The scored versus unscored split. The exam has 100 multiple-choice questions, but the public sources do not state how many are scored and how many, if any, are unscored. You cannot identify which questions might not count, so there is no safe place to coast.
• The pass rate. IAHSS does not publicly disclose how many candidates pass. Any specific percentage you see quoted elsewhere is not backed by the official record. We cover what is and is not known in our CHSO pass rate breakdown.
• The largest domain. The eight course modules are teaching units, not a weighted exam blueprint. There is no verified statement that one module carries more questions than another.
• Open-book, calculator, adaptive and live-proctor rules. These are unverified in the public sources. Confirm the delivery rules shown in your own exam purchase before test day rather than assuming.

The practical consequence is straightforward. Because the weighting is unknown, a strategy that bets on mastering a few favorite topics and ignoring the rest is a gamble the public information gives you no basis to take.

Format and Clock: 100 Questions in 90 Minutes

The exam is 100 multiple-choice questions delivered online in a single, uninterrupted 90-minute session. Do the arithmetic: 90 minutes across 100 questions averages out to roughly 54 seconds per question. That is workable for knowledge-recall items and tighter for scenario-style questions that require you to read a situation, weigh options and select the most appropriate response.

The "uninterrupted" detail matters more than candidates expect. You are committing to a continuous block of time, not a session you can pause and resume. Before you begin, plan your environment: a stable connection, a quiet space, and no scheduled obligations that could pull you away partway through.

If you need an accommodation, an accommodation request process is available. Start that conversation early rather than the week of your exam. Our CHSO exam dates and scheduling guide covers how timing and access windows fit together.

Doing the Math on a 100-Question Exam

Since the exam has 100 questions and the criterion is 70%, the intuitive reading is that you need roughly 70 correct answers. Because the scored/unscored split is undisclosed, treat that as a planning heuristic rather than a guarantee of how your result is calculated. What the heuristic does give you is a useful way to think about error budget.

If every question counts, you can miss roughly 30 and still meet the criterion. That sounds generous until you consider how mistakes cluster. A candidate who is strong on three or four modules and weak on the rest does not miss 30 questions evenly; they miss many in a few areas. A cluster of misses in one or two modules can consume the entire budget.

A sensible personal benchmark is to set an internal target meaningfully above 70% on practice material, so that real-exam surprises, such as awkward phrasing or a topic you only half remember, do not push you under the line. You can test yourself against realistic question styles on our CHSO practice test platform.

Eight Course Modules, Eight Targets

The current IAHSS Basic eLearning v1.2 course is organized into eight teaching modules, and a supporting public objectives document lists 33 subtopics across them. Important caveat: these modules are teaching units, not official weighted exam domains, and they are not a verified exhaustive exam blueprint. They are still the best publicly visible map of what the Basic credential covers, and they map directly to the eight content areas used on this site. Our complete guide to the eight CHSO content areas goes deeper on each.

Here is how to think about each one in terms of what a passing candidate should be able to do.

Because the 33 subtopics in the objectives document are spread across these eight modules and the weighting is unknown, the most defensible approach is to prepare every module to a comparable standard. Our CHSO study guide lays out a full preparation path, and the CHSO cheat sheet condenses the must-know facts for last-minute review.

Fees, Access Windows and Retake Mechanics

The cost structure interacts directly with how you think about the passing score, because a failed attempt means buying another exam. The published options are:

No separate member and non-member exam price tiers are published. If you fail, another exam purchase is required to retake. That makes a failed attempt a real cost, which is a practical argument for walking in prepared rather than testing the water. Keep in mind that the 60-day exam-only window and one-year bundle access are distinct from the five-year validity of the certification itself; they govern how long you can use the product, not how long the credential lasts. For a complete breakdown of spend, see our CHSO certification cost guide.

On eligibility, no current degree, experience-hour, employment-tenure or reference requirement is published. The eight-to-ten-hour course estimate is an estimate of course length, not a verified mandatory prerequisite for sitting the exam. Details are in our CHSO requirements guide.

Building a Margin Above 70%

Because the weighting is unknown and the format is time-constrained, the goal is not just to know the material but to know it well enough that you can answer quickly. Here is a short sequencing plan tied to the specific structure of this credential.

This sequence is a suggestion, not a requirement; the point is that scenario-based modules deserve proportionally more practice time because they are the hardest to answer quickly from memory alone. Pair it with timed runs so the 90-minute pace feels familiar before test day.

What Your Result Means for Your Career

Passing earns the Certified Healthcare Security Officer credential, which is valid for five years and renewed by retesting or advancing. No Basic CEU-only renewal route is verified in the public sources. Healthcare employers such as hospitals and health systems are the natural audience for a credential built specifically around healthcare security, and our CHSO jobs overview looks at where it fits.

On pay, be careful. There is no verified CHSO-specific salary premium, so be skeptical of any source that promises a particular figure. Our salary guide explains the qualitative picture, and our worth-it analysis helps you weigh the cost against your own goals.
