What This Cheat Sheet Covers (and What It Doesn't)
This page condenses the verifiable facts about the Manager of Landfill Operations (MOLO) credential from the Solid Waste Association of North America (SWANA) into a single scannable review. It is built for candidates who already know the basics and want one place to check numbers, categories, and rules before applying or sitting for the exam.
If you are brand new to the credential, start with What Is MOLO Certification? and come back here once the vocabulary is familiar. If you want a full preparation plan rather than a fact sheet, the MOLO Study Guide goes much deeper.
Credential Snapshot: SWANA's Manager of Landfill Operations
| Item | What the Sources Say |
|---|---|
| Issuing body | Solid Waste Association of North America (SWANA) |
| Credential | Manager of Landfill Operations (MOLO) |
| Editions | Separate U.S. and Canadian exams, each with its own Body of Knowledge |
| Testing delivery | Online, through Captus |
| Exam length | Three hours maximum; cannot be paused and resumed |
| Passing score | 70% |
| Results | Emailed within 24 hours |
| Exam window | Must be taken within six months of purchase |
| Validity | Three years |
One structural point trips up many candidates: approval comes before access. You submit your application, SWANA approves your eligibility, and only then do you gain access to the exam. Plan your timeline around that sequence, and see MOLO Exam Dates for scheduling considerations.
The Four Competency Categories at a Glance
SWANA organizes preparation around four job-competency categories. These are official headings used for preparation and readiness assessment, but they are unweighted: SWANA does not publish a percentage blueprint, so you cannot responsibly claim any one category is "worth the most." Treat all four as fair game.
Domain 1: Foundational
The grounding knowledge a landfill manager is expected to carry into every decision.
- General knowledge of landfill operations
- Regulation and permitting awareness
- Safety fundamentals
- Financial basics for a landfill operation
Domain 2: Strategic
Planning-level thinking: where the facility is going and how it protects itself against disruption.
- Planning and phase development
- Disaster contingencies
- Continuous improvement
- Equipment and asset decisions
Domain 3: Technical
The engineering and environmental systems that keep a landfill compliant and stable.
- Waste and cell operations, daily and final cover
- Leachate and landfill gas management
- Environmental controls, groundwater, and stormwater
- Infrastructure and closed landfills
Domain 4: Management
The people-and-communication side of running a facility.
- Communication with stakeholders
- Staffing and operational training
- Leadership and professional development
The 26 Job Functions You Should Be Able to Name
Each Body of Knowledge (U.S. edition dated September 2021; Canadian edition dated February 2022; both 54 pages) contains 26 job functions. A reliable self-test: can you list these and explain, in a sentence or two, what a manager is accountable for in each?
- General knowledge
- Regulation and permitting
- Safety
- Finance
- Equipment and assets
- Planning
- Disaster contingencies
- Improvement
- Operational training
- Phase development
- Scales
- Waste and cell operations
- Cover
- Restricted materials (Job Function 14, labeled differently by edition; see below)
- Ancillary activities
- Leachate
- Gas
- Environmental controls
- Groundwater
- Stormwater
- Infrastructure
- Closed landfills
- Communication
- Staffing
- Leadership
- Professional development
Notice how the list tilts toward real facility operations: scales, cover, leachate, gas, groundwater, stormwater. These are everyday responsibilities for the people who hire MOLO holders, such as municipal solid waste departments, regional authorities, and private landfill operators, and the exam expects you to reason about them as a manager, not just recite definitions. Browse MOLO Jobs for context on where the credential gets used.
Key Takeaway
Print the 26 job functions and rate yourself 1 to 5 on each. Your weakest scores, not your favorite topics, should drive your study hours. Most experienced operators are strong on cell operations and cover but thinner on finance, communication, and staffing.
Eligibility Math in One Table
Eligibility has three routes, all requiring municipal-solid-waste management experience plus an education component:
| Route | Experience | Education |
|---|---|---|
| A | Five years | High school diploma or GED |
| B | Four years | Relevant two-year degree |
| C | Three years | Relevant four-year bachelor's degree |

Exam-Day Mechanics
What is confirmed
- Online testing delivered through Captus
- Three hours maximum, with no pausing and resuming
- 70% required to pass
- Results emailed within 24 hours
- Assistance, mobile devices, and study aids are prohibited unless expressly allowed, per the SWANA Online Testing Conduct Policy
What a chapter document adds, with limits
A Northern Lights Chapter application form for Manitoba landfill operator certification describes the MOLO as 150 multiple-choice questions, online only. That is chapter-published evidence in a Canadian context. It is useful as a planning signal for question style (multiple choice), but it is not national confirmation of the current count or format for both editions. The same form's calculator or formula-sheet permission should not be assumed for either national exam.
Because the exam cannot be paused, remove interruptions before you start: stable internet, a quiet room, and a clear understanding of the conduct policy. For difficulty expectations, read How Hard Is the MOLO Exam?, and for scoring specifics see MOLO Passing Score.
U.S. vs. Canadian Edition: The One Label That Differs
SWANA offers separate U.S. and Canadian exams with separate registration pages and separate Body of Knowledge documents. The shared competency categories above apply to both, but jurisdiction-specific requirements must not be blended. The clearest example is Job Function 14:
| Edition | Job Function 14 Label |
|---|---|
| U.S. edition | Prohibited and Restricted Waste Materials Management |
| Canadian edition | Hazardous and Non-Hazardous Materials Management |
These are distinct labels with distinct jurisdictional scope. If you are testing in one country, study the Body of Knowledge for that edition, and do not assume regulatory references from the other apply. Download the document that matches your exam and use its terminology.
Fees, Retakes, and Renewal Numbers
| Item | Amount or Rule |
|---|---|
| Application/exam fee (SWANA member) | USD 250 |
| Application/exam fee (nonmember) | USD 400 |
| Membership and training | Separate costs, not included |
| Retake | Immediate retakes permitted, no numerical attempt limit, full fee each time |
| Renewal | 30 relevant PDHs, renewal application, USD 250 per discipline, before expiry |
| Renewal cycle | Every three years |
| Expired credential | Must retake and pass the exam |
Two practical notes. First, the member versus nonmember gap is USD 150, so compare that against the cost of membership before paying the higher fee. Second, PDH terminology replaced the older SWANA CEU language, so if you see "CEU" in older materials, translate it to PDH. The full cost picture, including training and membership, is in MOLO Certification Cost, and the career side is covered in Is the MOLO Certification Worth It? and the MOLO Salary Guide.
A Domain-Ordered Study Sequence
Because the categories are unweighted, the sequence below is built around dependency, not exam percentages: you need the regulatory and safety vocabulary before the technical systems make sense, and the management material lands better once you have the operational picture.
Foundational
- Read your edition's Body of Knowledge end to end once
- Drill regulation, permitting, safety, and finance job functions
- Note every U.S.-versus-Canada terminology difference that applies to you
Technical
- Leachate, gas, groundwater, and stormwater as connected systems
- Cover, cell operations, scales, and closed-landfill obligations
- Job Function 14 materials management for your edition
Strategic
- Phase development, planning, and disaster contingencies
- Equipment and asset decisions framed as manager-level tradeoffs
Management, then timed practice
- Communication, staffing, training, leadership, and professional development
- Timed multiple-choice sets across all four categories
Note that SWANA's FAQ states no course is required for certification, though a chapter training flyer from 2024 described course completion as required for that offering; the current national FAQ governs. The current U.S. course has 13 preparation modules, which are not 13 exam domains, and attending a course alone does not cover everything you need. See MOLO Training for options. For realistic scenario questions, build your timed practice with the MOLO practice tests.
What Is Not Published (Do Not Memorize Rumors)
Part of exam readiness is knowing what no one can honestly tell you. In the national sources reviewed, the following are not published:
- A universal, confirmed question count for both editions
- Scored versus unscored question allocation
- An aggregate candidate pass rate (see MOLO Pass Rate for what can and cannot be said)
- Percentage weighting or a "highest-weighted" category
- Whether the exam is open-book, adaptive, or which exact remote-proctoring mode applies
- Calculator rules for either national edition
If a forum post quotes a specific weighting or pass percentage, treat it as unverified. Confirm anything exam-format related directly with SWANA when your application is approved, since access to the exam follows approval.
Key Takeaway
Your cheat sheet is only as trustworthy as its sources. Anchor on SWANA's Body of Knowledge for your edition, SWANA's Become Certified page for process, and its maintaining-certification page for renewal. Everything else is supporting context.
FAQ
Here it means Manager of Landfill Operations, a certification from the Solid Waste Association of North America (SWANA). For plain-language background, see What Does MOLO Stand For?
You need 70% to pass, and the exam lasts at most three hours without the option to pause. You must take it within six months of purchase, and results are emailed within 24 hours.
Yes. Immediate retakes are permitted with no numerical attempt limit, but each attempt costs the full fee (USD 250 for members, USD 400 for nonmembers).
Certification is valid for three years. Before it expires, submit a renewal application, document 30 relevant PDHs, and pay USD 250 per discipline. An expired credential requires retaking and passing the exam.
No. SWANA runs separate U.S. and Canadian exams with separate Body of Knowledge documents. They share the same 26-job-function structure but differ in jurisdiction-specific content, most visibly the Job Function 14 label.
