FREE APICS CPIM Exam Guide 2026: Pass ASCM Certified in Planning and Inventory Management (Single Exam, Version 8.0 through May 31, 9.0 from June 1, 20-Week Plan)

APICS CPIM Exam Guide 2026: The Most Specific Walkthrough of ASCM's Planning and Inventory Credential

The APICS Certified in Planning and Inventory Management (CPIM) from ASCM (the Association for Supply Chain Management) is the gold-standard credential for professionals who plan, schedule, and control internal supply chain operations - manufacturing, materials, inventory, capacity, and the master schedule. Unlike CSCP (which is end-to-end external supply chain) or CLTD (logistics, transportation, and distribution), CPIM owns the inside-the-four-walls discipline: MPS, MRP, capacity planning, S&OP, demand management, lean, and inventory cost control.

Critical 2026 update: CPIM is no longer a two-part exam. ASCM retired the Part 1 + Part 2 model with CPIM Version 8.0 (launched June 1, 2023; last day to sit legacy Part 1/Part 2 v7.0 exams was February 1, 2024). CPIM is now a SINGLE exam with 150 multiple-choice questions in 3.5 hours covering 8 modules. A further update (CPIM Version 9.0) launches June 1, 2026 - last day to sit v8.0 is May 31, 2026. The v9.0 bundle is available for purchase beginning February 3, 2026.

This 2026 guide is engineered to be the most specific, most current, and most actionable CPIM study resource on the open web. It covers the single-exam structure, the CPIM v8.0 -> v9.0 transition happening mid-2026, exact 2026 ASCM fee math (member vs non-member, bundle vs exam-only), per-module deep dives with the formulas you must memorize (EOQ, safety stock, MAPE, MRP bill-of-materials explosion, finite vs infinite capacity), a 20-week study plan, recertification via 75 professional development points (PDPs) every 5 years, and a CPIM vs CSCP vs CLTD decision matrix.

Every core study resource referenced here is free or covered by ASCM membership. Our practice bank and AI tutor are free. You do not need a $3,000 boot camp to earn CPIM.

What CPIM Is (and Why It Matters in 2026)

CPIM is the operations professional's certification - the one ASCM positions as the "internal supply chain" credential covering manufacturing planning, scheduling, and inventory management. It is built around the APICS body of knowledge (production planning, MRP, MPS, capacity planning, lean, theory of constraints, JIT, kanban, S&OP) and the APICS Dictionary vocabulary that dominates Fortune 500 operations and supply chain organizations.

CPIM signals that you can:

• Lead the Sales and Operations Planning (S&OP) process - aggregate planning, demand-supply balancing, executive S&OP.
• Build and maintain the Master Production Schedule (MPS) - rough-cut capacity planning, time fences, available-to-promise.
• Run MRP - bill of materials explosion, gross-to-net, planned order generation, action messages.
• Plan capacity - resource requirements planning, rough-cut capacity planning, capacity requirements planning, finite vs infinite scheduling.
• Manage inventory - EOQ, safety stock, ABC classification, inventory cost (carrying, ordering, stockout), cycle counting.
• Apply Lean / TOC / JIT - kanban sizing, takt time, drum-buffer-rope, value stream mapping.
• Forecast demand - moving average, exponential smoothing, MAPE, bias, tracking signal.
• Mitigate the bullwhip effect through information sharing, smaller lot sizes, and channel coordination.

In the U.S. in 2026, Supply Chain Analysts and Planners earn $65,000-$95,000, Operations Managers earn $95,000-$130,000, and Supply Chain Managers/Directors earn $120,000-$175,000 (Glassdoor, BLS, Robert Half 2026 Salary Guide). CPIM is frequently listed as "preferred" or "required" on production planner, materials manager, master scheduler, supply chain analyst, and operations manager postings - especially in manufacturing, CPG, pharma, automotive, aerospace, and 3PL.

CPIM stacks naturally with CSCP (end-to-end external supply chain) and CLTD (logistics, transportation, distribution). The full ASCM trifecta (CPIM + CSCP + CLTD) is the recognizable signal for senior supply chain leaders.

CPIM Exam Structure: Single Exam, 8 Modules (2026)

CPIM is a SINGLE exam as of v8.0. The legacy two-exam Part 1 + Part 2 model (v7.0) was retired - the last day candidates could sit v7.0 Part 1 or Part 2 was February 1, 2024. Since June 1, 2023, there has been one combined exam covering all 8 modules. v9.0 (launching June 1, 2026) continues the single-exam structure.

If you see a "CPIM Part 1" or "CPIM Part 2" study plan or prep book in 2026, it is written for the retired v7.0 exam and should not be used without verifying coverage against the v8.0 / v9.0 ECM.

Strategic note: Because one exam now covers the entire legacy Part 1 + Part 2 body of knowledge, budget closer to the combined study hours you previously saw advertised for both parts. Plan 150-200 total prep hours for first-time candidates without deep operations experience.

CPIM Eligibility: NO Prerequisites

Unlike PMP, CBAP, or CSCP-equivalent credentials at other bodies, CPIM has no formal eligibility requirements:

• No degree required
• No work experience required
• No references required
• No prerequisite courses required

You can register for CPIM the day you join ASCM (or as a non-member). This makes CPIM uniquely accessible for career-changers, students, and practitioners without formal supply chain titles. Industry recommendation (not enforced): 1-2 years of operations or supply chain experience helps you contextualize the material; with zero experience, plan an extra 6-8 weeks of study.

CPIM Version 8.0 / 9.0 Content Overview

The current CPIM exam content is Version 8.0, released June 1, 2023. CPIM Version 9.0 launches June 1, 2026 - the last day to sit v8.0 is May 31, 2026. The v9.0 bundle is available for purchase starting February 3, 2026, with the v9.0 ECM published by ASCM for candidates preparing for the transition.

ASCM publishes the official CPIM Exam Content Manual (ECM) detailing every learning objective. Verify the current ECM version on ascm.org before sitting.

CPIM 8 Modules (single combined exam)

ASCM does not publish a per-module percentage weighting on the public ECM for v8.0 / v9.0 - module weightings in third-party guides are estimates. Treat all 8 modules as test-relevant and do not under-study any. Verify current ECM on ascm.org/learning-development/certifications-credentials/cpim/ecm/ before sitting.

Per-Module Deep Dives with Formulas

Module 1: Align the Supply Chain to Support the Business Strategy

The strategic frame for everything that follows. Tests vocabulary from ISCM (Integrated Supply Chain Management), supply chain strategy alignment, sustainability (Triple Bottom Line: people, planet, profit), and the bullwhip effect.

Bullwhip effect causes (memorize):

1. Demand forecast updating (each tier reforecasts independently)
2. Order batching (economies of scale in ordering create lumpy demand upstream)
3. Price fluctuations (promotions distort true demand signal)
4. Rationing and shortage gaming (customers over-order when supply is tight)

Bullwhip mitigations: information sharing (POS data sharing, VMI), smaller lot sizes (EDI, electronic ordering), every-day-low-pricing (EDLP), allocation by historical share rather than current orders.

Sustainability frameworks: Triple Bottom Line, ISO 14000, Sustainability Accounting Standards Board (SASB), GRI Standards, Scope 1/2/3 emissions.

Module 2: Conduct Sales and Operations Planning (S&OP)

S&OP is the cross-functional, executive-led process that balances demand and supply over a 12-18+ month rolling horizon at the product family level (not SKU level - that is MPS).

Five-step S&OP process (memorize):

1. Data gathering (sales history, forecasts, supply data)
2. Demand planning (consensus forecast, marketing/sales input)
3. Supply planning (capacity, inventory, production strategy)
4. Pre-S&OP meeting (resolve conflicts, build recommendations)
5. Executive S&OP (final approval, decision-making)

Production strategies (frequently tested):

Module 3: Plan and Manage Demand

Forecasting and customer relationship management. The formula-heavy module.

Forecast accuracy formulas (memorize):

• MAD (Mean Absolute Deviation) = Σ |Actual − Forecast| / n
• MAPE (Mean Absolute Percent Error) = (Σ |Actual − Forecast| / Actual) / n × 100%
• Bias = Σ (Actual − Forecast) / n (positive bias = under-forecasting; negative = over-forecasting)
• Tracking Signal = Running Sum of Forecast Errors (RSFE) / MAD; out-of-control if outside ±4 (typical) or ±6 (loose) bounds

Forecasting methods:

Smoothing constant alpha (single exponential smoothing): higher alpha (closer to 1) = more weight on recent data, more reactive; lower alpha (closer to 0) = more smoothing, less reactive. Typical range 0.1-0.3.

Module 4: Plan and Manage Supply (MPS / MRP / CRP - the heaviest formula module)

The MPS/MRP/CRP triad. Heavy formulas and scenario items.

MPS (Master Production Schedule) - what we will produce, by SKU, by time bucket:

• Time fences: Demand Time Fence (frozen, only emergencies), Planning Time Fence (firm, system-suggested changes need approval), Beyond Planning Time Fence (free, system auto-adjusts).
• Available-to-Promise (ATP) = Scheduled MPS receipts in the period − customer orders already booked through next MPS receipt.
• Rough-Cut Capacity Planning (RCCP) = MPS × bill of resources (key work centers) to validate MPS feasibility before committing to MRP.

MRP (Material Requirements Planning) - the exploded plan for components:

MRP inputs: MPS, BOM (bill of materials), inventory record (on-hand, on-order, allocated), planning factors (lead time, lot size, safety stock).

MRP logic (gross-to-net per parent-component):

1. Gross requirements = exploded from parent demand × BOM quantity per
2. Net requirements = Gross requirements − Scheduled receipts − Projected on-hand
3. Planned order receipts = Net requirements adjusted to lot-size policy
4. Planned order releases = Planned order receipts offset back by lead time

Lot-sizing rules: Lot-for-lot (LFL), Fixed Order Quantity (FOQ), Period Order Quantity (POQ), EOQ, Least Total Cost, Least Unit Cost, Wagner-Whitin (optimal but complex).

CRP (Capacity Requirements Planning) - validates MRP planned orders against detailed work-center capacity. Inputs: planned and released orders, routings, work-center calendar.

Finite vs infinite capacity:

• Infinite scheduling (CRP default) = assumes infinite capacity, generates load profile, planner manually levels.
• Finite scheduling = constrains to actual capacity, shifts orders forward/backward to fit.

Module 5: Plan and Manage Inventory

The inventory math module. EOQ + safety stock + ABC are guaranteed exam topics.

EOQ (Economic Order Quantity):

• EOQ = sqrt(2DS / H) where D = annual demand (units), S = setup/order cost ($ per order), H = holding cost ($ per unit per year)
• Total annual cost (TAC) = (D/Q × S) + (Q/2 × H) - balancing ordering and holding
• EOQ assumptions: constant demand, constant lead time, no quantity discounts, instant replenishment (or production EOQ variant for gradual replenishment).

Safety Stock:

• Safety Stock (statistical) = Z × σL where Z = safety factor for desired service level, σL = standard deviation of demand during lead time
• Service level Z values (memorize): 90% = 1.28, 95% = 1.65, 97.5% = 1.96, 99% = 2.33
• Reorder Point (ROP) = (Demand during lead time) + Safety Stock = (d × LT) + SS

ABC Classification (Pareto, 80/20):

Inventory cost categories (memorize):

1. Carrying / Holding cost (capital, storage, obsolescence, insurance, shrinkage) - typically 20-40% of inventory value/year
2. Ordering / Setup cost (purchase order processing, setup labor, inspection)
3. Stockout cost (lost sales, expediting, customer dissatisfaction) - hardest to quantify
4. Capacity-related cost (overtime, subcontracting)

Cycle counting vs physical inventory: cycle counting is continuous, ABC-prioritized (A items counted more often); physical inventory is annual, full-shutdown - cycle counting is preferred per APICS.

Module 6: Plan, Manage, and Execute Detailed Schedules

Detailed scheduling translates the MPS into executable shop-floor schedules. This module contains the bulk of the Lean / TOC / JIT / kanban vocabulary and calculations.

Lean: 5S, value stream mapping, kaizen, SMED, poka-yoke, jidoka, heijunka, 7 wastes (TIMWOOD + defects), pull systems.

Theory of Constraints (TOC): 5 focusing steps (Identify, Exploit, Subordinate, Elevate, Repeat); drum-buffer-rope scheduling; throughput accounting.

JIT / Kanban: kanban card calculation N = (D × LT × (1 + α)) / C where N = number of cards, D = demand rate, LT = lead time, α = safety factor, C = container size. Round up.

Takt Time = Available production time / Customer demand rate. Defines the rhythm at which a process must produce to meet demand. Not the same as cycle time (actual production time per unit).

Finite vs infinite capacity: Infinite scheduling (CRP default) generates a load profile; finite scheduling auto-adjusts orders to fit capacity constraints.

Module 7: Plan and Manage Distribution

DRP (Distribution Requirements Planning) applies MRP gross-to-net logic to multi-echelon distribution networks: gross requirements from downstream DCs explode through transit time and lot sizes to upstream supply points.

Transportation modes: rail, truck (LTL / FTL), air, ocean, intermodal, pipeline - each with distinct cost/speed/reliability tradeoffs.

Warehousing: cross-docking, put-away strategies, slotting, 3PL / 4PL relationships, customer service segmentation.

Reverse logistics: returns management, recycling / refurbish / remanufacture / dispose, closed-loop supply chain, sustainability.

Module 8: Manage Quality, Continuous Improvement, and Technology

Quality: SPC, control charts (X-bar / R), process capability Cp / Cpk (Cpk = min((USL - mean)/3σ, (mean - LSL)/3σ)), Six Sigma DMAIC, PDCA, cost of quality (prevention, appraisal, internal failure, external failure).

Continuous improvement: kaizen events, A3 problem solving, root cause analysis (5 Whys, fishbone / Ishikawa).

Supply chain technology: ERP, APS, WMS, TMS, blockchain, IoT sensors, digital twin, AI / ML for forecasting, RPA in procurement - v9.0 gives technology expanded emphasis vs v8.0.

CPIM Cost Stack (2026, U.S. - single exam)

Key insight: The exam-only path saves roughly $1,000 but requires you to assemble study materials independently. The bundle includes the CPIM Learning System (ASCM's authoritative self-paced curriculum with practice tests, web access, smart study tools), the 2nd Chance Exam (free retake if you fail the first), and ASCM membership. For self-disciplined learners with the ASCM Supply Chain Dictionary and a prep book or two, the exam-only path is viable. For first-time supply chain learners, the Learning System is worth the premium - especially with the free retake hedge. Verify all 2026 fees on ascm.org - pricing changed with the v9.0 rollout and ASCM updates pricing periodically.

Registration via ASCM (Step-by-Step)

1. Create an ASCM profile at ascm.org. Decide on member vs non-member (Plus member $219/year saves ~$490 on the exam-only price and ~$900 on the bundle - membership pays for itself with a single CPIM purchase).
2. Purchase the CPIM bundle or exam-only from the ASCM store. If you are sitting between Feb 3 - May 31, 2026, decide whether to target v8.0 (existing content, retires May 31) or v9.0 (bundle on sale Feb 3, exam live June 1).
3. Receive Authorization to Test (ATT) email from ASCM with a unique code, valid for 12 months from issuance.
4. Schedule via Pearson VUE at pearsonvue.com/asc - choose test center or OnVUE online proctored.
5. Sit the exam. Results are provisional at the end of the session and confirmed by ASCM within ~5 business days.
6. If you fail with the bundle, use the 2nd Chance Exam (included) to retake at no additional exam fee (conditions apply; typically within a defined window).

Recertification: 75 PDPs Every 5 Years

CPIM is valid for 5 years. To maintain the credential you must earn 75 professional development points (PDPs) during the cycle and pay a maintenance fee. Verify current 2026 maintenance fee on ASCM's Certification Maintenance page.

PDP categories (log in your ASCM Maintenance account):

Practical path to 75 PDPs: 25 PDPs from one ASCM CONNECT conference, 20 PDPs from work experience, 15 PDPs from quarterly webinars, 10 PDPs from chapter volunteer work, 5 PDPs from a published article. Most active practitioners hit 75 across 5 years without extra effort.

20-Week Study Plan (Built for Working Professionals)

This schedule assumes 8-10 hours per week across 20 weeks (~160-200 total hours), covering all 8 CPIM modules in a single prep cycle. First-time supply chain learners with no operations background should add 4-6 weeks.

CPIM 20-Week Plan (Single Exam)

Recommended CPIM Resources (Free + Paid)

Test-Day Strategy

Pacing: 150 questions / 210 minutes = 84 seconds per question average. Most CPIM items are 1-3 sentences, but expect 20-35 calculation items across the exam (EOQ, safety stock, MAPE, ROP, kanban card, takt time, Cp/Cpk). Budget 2-3 minutes for calculation items and 60 seconds for vocabulary recall.

Calculator policy: ASCM provides an on-screen calculator for OnVUE / Pearson VUE delivery. Practice with a basic 4-function + sqrt calculator since that is what you get. Do not bring a physical calculator (not permitted).

Scratch paper / whiteboard: Used heavily for MRP explosions, BOM trees, EOQ formulas, and time fence diagrams. Pearson VUE provides erasable noteboards (test center) or digital scratch (OnVUE).

Three-pass strategy:

1. First pass - answer everything you know in <60 seconds. Flag the rest.
2. Second pass - work through flagged calculation items methodically.
3. Third pass - review flags and best-guess any unanswered items (no penalty for wrong answers).

ASCM-speak discipline: When two answer choices sound equivalent, pick the one using ASCM Supply Chain Dictionary terminology (planned order release, time fence, action message, projected available balance) over generic operations vocabulary (work order, frozen window, alert, on-hand).

Common CPIM Pitfalls

1. Using a "Part 1 / Part 2" study plan. That model was retired Feb 1, 2024 with v7.0. In 2026 CPIM is a single exam of 150 questions covering all 8 modules. Prep books older than 2024 may be written for the old structure - verify.
2. Skipping ASCM Dictionary memorization. CPIM is brutally vocabulary-heavy. ASCM uses specific terms - know them cold (e.g., "scheduled receipt" vs "planned order receipt" vs "released order").
3. Ignoring the v8.0 -> v9.0 transition. If you are sitting between June 1, 2026 and late 2026, you sit v9.0. Verify your prep materials cover the v9.0 ECM (technology module gets expanded emphasis).
4. Memorizing formulas without understanding. Knowing EOQ = sqrt(2DS/H) is 30% of the battle. The other 70% is recognizing which problem needs EOQ vs Production Order Quantity vs POQ.
5. Under-studying the Supply module. MRP gross-to-net mechanics, time fences, ATP, and CRP integration deserve heavy practice - the Supply and Detailed Scheduling modules together carry a disproportionate share of formula items.
6. Mixing MAPE and MAD. MAD is in units; MAPE is a percentage. MAPE = (|error| / actual) averaged.
7. Tracking signal mistakes. Tracking Signal = RSFE / MAD. RSFE is the running sum of (Actual − Forecast), not absolute values. Out-of-control bounds are typically ±4.
8. EOQ assumption traps. EOQ assumes constant demand and instant replenishment. If a problem includes gradual replenishment, the answer is Production Order Quantity (EPQ), not EOQ.
9. Confusing finite vs infinite capacity. Infinite scheduling (default CRP) generates a load profile; finite scheduling auto-adjusts orders to fit capacity.
10. Misclassifying ABC items. A items are HIGH $ value but FEW in count. Do not confuse with quantity rankings.
11. Lean vs TOC vs JIT confusion. Lean = waste elimination + flow + pull. TOC = constraint identification + 5 focusing steps + DBR. JIT = pull system using kanban for inventory minimization. They overlap but have distinct vocabulary.
12. Not practicing full 150-question timed simulations. Mental stamina across 3.5 hours plus calculation pacing is its own skill. Do at least 2-3 full simulations before test day.

CPIM vs CSCP vs CLTD: Decision Matrix

ASCM offers three core supply chain credentials. They are complementary - not competing - but most professionals start with one based on current role.

Decision rules:

• Start with CPIM if you work inside the four walls (planning, scheduling, manufacturing, materials, inventory). Most operations and manufacturing professionals start here.
• Start with CSCP if you work end-to-end (network design, strategic planning, multi-tier supplier management, S&OP at the enterprise level). Holds an eligibility prerequisite.
• Start with CLTD if you work in logistics, transportation, distribution, warehousing, or 3PL. Has no prerequisite.
• Stack all three if you target VP / SVP / Chief Supply Chain Officer roles. The full ASCM trifecta plus a master's in supply chain is the standard senior signal.

Common Gotchas Competitor Guides Miss

• CPIM is a SINGLE exam in 2026, not Part 1 + Part 2. The two-exam Part 1 / Part 2 model was retired with v7.0 on February 1, 2024. Any guide or prep book still describing CPIM as "two parts" is outdated.
• The "P" in CPIM changed meaning. Old: Certified in Production and Inventory Management. Current: Certified in Planning and Inventory Management (updated with v8.0). Your badge and the community still say "APICS CPIM" either way.
• v8.0 retires May 31, 2026; v9.0 launches June 1, 2026. If you bought the v8.0 bundle, plan to sit by May 31, 2026. The v9.0 bundle is available for purchase starting February 3, 2026.
• CPIM has no flat percentage pass score. ASCM uses a scaled score 200-350 with 300 as the cut. Per-module performance bands are reported.
• 150 questions includes some unscored pretest items. Treat every question seriously - you do not know which is unscored.
• The 12-month ATT window is firm. If you do not sit within 12 months of receiving the ATT, you forfeit the exam fee.
• Re-examination requires re-purchasing the exam fee unless you have a 2nd Chance Exam. The bundle typically includes a 2nd Chance Exam - use it if you fail the first attempt (conditions apply).
• The bundle (Learning System + Exam + 2nd Chance + Membership) and exam-only paths are separate purchases. Once you buy exam-only, you cannot bundle-upgrade for a discount.
• ASCM Supply Chain Dictionary is essential. Every term in the ECM is defined in the Dictionary - and exam questions assume Dictionary precision. (This is the successor to the long-standing APICS Dictionary.)
• OnVUE setup is strict. No paper, no second monitor, no off-screen glances, no phone in reach. Private room with door closed. Plan a 15-30 minute proctor check-in before the 3.5-hour clock starts.
• MPS lives at the SKU level; S&OP lives at the product family level. A classic exam trap conflates the two.
• DRP is MRP applied to distribution networks. Same gross-to-net mechanics, different inputs (DC demand instead of BOM explosion).
• Kanban card formula: N = D × LT × (1 + α) / C. Memorize - it is a frequent calculation item in Module 6 (Detailed Schedules).
• Takt time = Available time / Demand. Not "cycle time" - cycle time is the actual production time per unit; takt time is the demand-derived target.
