MOLO Pass Rate 2026: What the Data Shows

What the Public Record Actually Says About MOLO Pass Rates

If you searched for a single percentage that tells you how many candidates pass the Manager of Landfill Operations (MOLO) exam, here is the direct answer: the national SWANA sources reviewed for this article do not publish one. There is no annual pass-rate report, no first-attempt versus repeat-taker breakdown, and no published count of how many people sit the exam in a given year.

That may feel unsatisfying, but it is the accurate state of the evidence. This article exists to show you what the data does support, what it cannot support, and how to turn the real, published figures into a sound preparation strategy. For a broader view of exam difficulty, see our guide on how hard the MOLO exam is.

Why No Aggregate Pass Rate Is Published

Several features of this credential make a clean pass-rate statistic hard to produce, even for the certifying body.

• Two geographic editions. SWANA offers separate U.S. and Canadian versions, each with its own Body of Knowledge. A single blended pass rate would mix two populations tested against jurisdiction-specific regulatory content.
• Unlimited retakes. Because there is no numerical attempt limit, "pass rate" becomes ambiguous. Is it the share of attempts that succeed, the share of people who eventually succeed, or the share who succeed on the first try? Each definition produces a very different number.
• Self-selection through eligibility. Candidates must already have years of solid waste management experience before applying, so the test population is not a general audience.
• Unpublished scoring detail. The retrieved national sources do not state how many questions are scored versus unscored, so even the denominator of a candidate's score is not publicly itemized.

Any website quoting a precise MOLO pass percentage without citing a SWANA document is, at best, repeating an anecdote and, at worst, importing a number from a different credential that shares the same acronym. Be skeptical.

The Numbers That Are Published

While the pass rate is absent, several hard figures are available and genuinely useful. These are the facts you can plan around.

The 70% threshold is the single most important published number for your planning. For a deeper look at how that standard works, read our breakdown of the MOLO passing score. For the money side, our MOLO certification cost guide covers how membership, training, and exam fees stack up.

Who Even Reaches the Exam: The Eligibility Filter

Pass rates for experience-gated credentials are shaped heavily by who is allowed to apply. MOLO is gated tightly, and application approval comes before you can access the exam at all. The eligibility routes are:

1. Five years of municipal solid waste management experience plus a high school diploma or GED; or
2. Four years of experience plus a relevant two-year degree; or
3. Three years of experience plus a relevant four-year bachelor's degree.

On every route, you also need at least two years of discipline-related management or supervisory experience and direct responsibility for daily operations. That management requirement is not automatically added on top of the experience total, so read the route language carefully. Our MOLO requirements guide walks through qualifying in detail.

Format Evidence and Its Limits

Candidates often ask how many questions are on the exam. The honest answer requires care. One chapter-published document, the Northern Lights Chapter's Manitoba landfill operator certification application, describes MOLO as 150 multiple-choice questions delivered online only, and directs MOLO applicants to SWANA.org. That is useful evidence, but it is a chapter document in a Canadian context. It does not confirm the current question count or format for both national editions, and the national sources reviewed do not state a universal count.

Likewise, the same form mentions calculator and formula-sheet permission, but that cannot be generalized to both national variants. The SWANA Online Testing Conduct Policy prohibits outside assistance, mobile devices, and study aids unless expressly allowed. Universal open-book permission, calculator rules, adaptive delivery, and the precise remote-proctoring mode were not verified. Before exam day, confirm the rules shown in your own approved application.

What You Are Being Tested On

SWANA organizes the competencies into four unweighted categories used for preparation and readiness assessment. Importantly, these are not a published percentage-weighted exam blueprint, and no official highest-weighted category has been established. The four categories supplied are Foundational, Strategic, Technical, and Management. For a full walkthrough, see our guide to the MOLO exam domains.

Each Body of Knowledge contains 26 job functions. Rather than memorize them as a list, it helps to group them by the four categories as a study aid, keeping in mind this grouping is a preparation device, not an official mapping.

The Jurisdictional Wrinkle in Job Function 14

One detail illustrates why the two editions are not interchangeable. Job Function 14 is titled Prohibited and Restricted Waste Materials Management in the U.S. edition but Hazardous and Non-Hazardous Materials Management in the Canadian edition. If you are testing in one jurisdiction, study that edition's Body of Knowledge and its regulatory framing rather than blending the two. Our MOLO study guide explains how to work from the correct document.

Retake Mechanics and What a Miss Costs

Because retakes are permitted immediately and without a stated attempt limit, a failed attempt is not a lockout. But the full fee applies every time: USD 250 for members or USD 400 for nonmembers. That makes the financial case for thorough first-attempt preparation straightforward, and it makes membership worth weighing, since the member fee is lower. Membership and training are priced separately, so compare your total outlay.

Remember also the six-month window. Once you purchase the exam, you must take it within six months. Build your preparation timeline backward from that deadline instead of buying early and hoping for motivation. For scheduling specifics, see our MOLO exam dates guide.

A Domain-Sequenced Preparation Plan

Since no category is officially weighted more heavily, spread effort across all four rather than gambling on one. This sample sequence ties each stretch to a domain and explains the reasoning. Adjust the length to fit your six-month purchase window.

How to Spot Unreliable Pass-Rate Claims

Because the real number is unpublished, the internet fills the gap with guesses. Apply these checks before trusting any figure.

• No source, no trust. A legitimate figure should cite a SWANA document or release. If it does not, treat it as unverified.
• Check which credential it describes. The acronym is shared with unrelated credentials. A statistic that mentions a different certifying body, different fee, or different format is not about the SWANA Manager of Landfill Operations exam.
• Watch the definition. A "pass rate" could mean per-attempt, per-person, or first-attempt. Without a stated definition it is not comparable to anything.
• Beware round, confident numbers. Precise-sounding percentages with no methodology are a red flag.

If you are weighing whether the credential is worthwhile despite the missing statistic, our analyses of whether MOLO certification is worth it and the MOLO salary guide give you a decision framework grounded in what is verifiable.
