Certification in Logistics, Transportation and Distribution (CLTD)

What to Expect on Exam Day

The APICS Certified Supply Chain Professional (CSCP) exam consists of 150 multiple-choice questions to be completed in 3.5 hours (210 minutes), delivered by computer at a Pearson VUE test center or through Pearson's OnVUE remote-proctoring option. Of those 150 questions, 130 count toward your score and 20 are unscored pretest items mixed in at random. You won't be able to tell which questions are unscored, so every question deserves your full attention. ASCM scores the exam on a scaled range of 200 to 350, and you need a score of 300 to pass.

That works out to roughly 1.4 minutes per question on average, but the pacing rarely feels even. A chunk of the exam is straightforward recall — definitions, named frameworks, regulatory terms — while another chunk presents a short operational scenario (a warehouse layout problem, a mode-selection trade-off, an import compliance situation) and asks you to pick the best response among several plausible ones. Those scenario questions take longer to work through, so budget your time with that in mind rather than assuming a flat pace across all 150.

It's also worth knowing this isn't the same exam it was a few years ago. ASCM relaunched CLTD in February 2025 with updated content on sustainability, AI's role in logistics, and risk management woven more directly into the existing modules, aligned to the Supply Chain Operations Reference (SCOR) model. If you're studying from older materials, some of what you're seeing may not reflect current emphasis.

Domain Breakdown

ASCM organizes the current CLTD body of knowledge into nine domains. The association has not published exact scoring-weight percentages for this revised version the way it did for the prior edition, so treat the list below as a coverage map rather than a weighted study plan — and don't assume any one domain gets skipped just because a number isn't attached to it.

The Topics Candidates Consistently Underestimate

A few areas trip up candidates more often than the module list suggests:

• Transportation cost math. Landed cost calculations, demurrage and detention charges, and backhaul economics show up as word problems, not formulas to recite. Candidates who only memorized mode characteristics (truck vs. rail vs. ocean) get caught out when a question asks them to actually compare costs.

• Customs and trade documentation. Global Logistics questions lean on specifics — Incoterms responsibilities, which party bears duty liability, what documentation accompanies an export shipment — that are easy to skim past if you haven't worked in an import/export role.

• Reverse logistics decision-making. Questions comparing in-house processing costs against third-party logistics (3PL) pricing structures require adding up all the component fees, not just comparing headline rates.

• The newer sustainability and risk content. Because this material was only added in the February 2025 revamp, there's less established prep coverage for it circulating than for the long-standing warehouse and transportation domains — which ironically makes it a spot where under-preparation is common right now.

How to Use Practice Tests Effectively for CLTD Exam

Because CLTD leans on scenario-based reasoning rather than pure recall, the most useful way to practice is to work through the "why" behind each answer choice, not just confirm whether you picked correctly. When a question involves a calculation — cost comparison, EOQ, a landed-cost figure — work it out by hand instead of pattern-matching to the answer that "looks right." That habit transfers directly to exam day, where the same kind of applied math appears dressed up in a different business context.

It also helps to run practice sessions timed at roughly the  pace (about 1.4 minutes per question) so you get a feel for how much time scenario questions actually eat into your buffer. Candidates who only practice untimed tend to be surprised by how tight 210 minutes feels once several multi-step questions land in a row Need additional preparation?

Common Mistakes That Cause Retakes

• Treating CLTD like a vocabulary exam and skipping hands-on practice with the transportation and inventory calculations

• Studying primarily from pre-2025 materials and missing the sustainability, AI, and risk management content added in the relaunch

• Spending disproportionate time on Warehouse and Transportation because they feel intuitive, while under-preparing Global Logistics and its documentation-heavy details

• Poor pacing — running out of time on the back half of the exam because early scenario questions ate more minutes than planned

• Not reviewing flagged or uncertain answers before submitting, especially on questions with more than one technically defensible choice

ASCM's  Study Timeline by Starting Experience Level

ASCM's own general guidance is to budget around 100 hours of study for each of its certification exams, though where that time goes should shift based on your background:

• New to logistics: Expect to need the fuller 100+ hours, spread across 8–10 weeks, with extra time on Warehouse, Inventory, and Transportation fundamentals before moving into scenario practice.

• Working logistics/supply chain professional: Domain knowledge from day-to-day work covers a lot of ground already. Four to six weeks focused on the areas outside your usual role (Global Logistics compliance details, the newer sustainability/risk content, and the calculation-heavy questions) is often enough.

• Retaking the exam: Go back through your practice results by domain rather than restarting from scratch. A retake attempt usually benefits more from two to three weeks of targeted review on the specific areas that pulled the score down than from a full re-study.

What's Changed Recently on CLTD Exam

ASCM relaunched CLTD at its Manifest 2025 conference in February 2025, retiring the prior nine-module structure (Logistics Overview and Strategy, Logistics Network Design, Sustainability and Reverse Logistics, Capacity Planning and Demand Management, Order Management, Inventory Management, Warehouse Management, Transportation, Global Logistics) in favor of the current lineup, which folds sustainability, AI's growing role in logistics operations, and risk management more directly into the existing domains and ties the whole framework to the SCOR model. The prior version's exam sunset on May 31, 2025, so anyone studying now is working against the current structure — worth double-checking if you're using older prep questions or a Learning System purchased before the update.
