The AACE CEP (Certified Estimating Professional) exam is a 5-hour, 120-question multiple-choice test plus a technical paper, administered by AACE International. The fee is $500 (member) or $625 (non-member). Candidates must demonstrate 8 years of cost-estimating experience (or a combination of education and experience). A passing score is 70%, and the credential is valid for 3 years subject to recertification. The CEP is widely recognized in process, EPC, mining, and building construction estimating.

1In AACE terminology, which cost type is incurred even if no production occurs and does not vary with output volume?

A.Variable cost

B.Direct cost

C.Fixed cost

D.Marginal cost

Explanation: Fixed costs (rent, salaried supervision, equipment depreciation, insurance) remain constant in total over a relevant range and do not change with output volume. They are time-related rather than activity-related and continue even when production stops.

2An estimator includes the cost of the project manager's salary across all jobs. Per AACE, this is best classified as which type of cost?

A.Direct labor cost

B.Indirect (distributable) cost

C.Sunk cost

D.Opportunity cost

Explanation: Indirect or distributable costs cannot be economically traced to a specific deliverable and are allocated across multiple cost objects. Project management, general supervision, and field office support are classic indirects per AACE Recommended Practice 11R-88.

3AACE Recommended Practice 18R-97 (Cost Estimate Classification — Process Industries) defines five estimate classes. Which class corresponds to the most preliminary, order-of-magnitude estimate with the lowest project definition?

A.Class 1

B.Class 2

C.Class 3

D.Class 5

Explanation: Per RP 18R-97, Class 5 is the earliest estimate (0%–2% project definition), used for concept screening with typical accuracy of -20% to -50% on the low side and +30% to +100% on the high side. Class 1 is the most definitive, prepared near 65%–100% project definition.

4An estimator scales the cost of a 100,000-bbl tank to estimate a 150,000-bbl tank using historical data and an exponent. Which estimating method is being used?

A.Bottom-up estimating

B.Parametric estimating

C.Definitive estimating

D.Three-point (PERT) estimating

Explanation: Parametric estimating uses statistical relationships between historical data and project variables (capacity, area, weight) to calculate a cost. The capacity-factored estimate, including the six-tenths rule (Cost2 = Cost1 x (Cap2/Cap1)^0.6), is a classic parametric technique on the AACE CEP exam.

5Using the AACE PERT (beta-distribution) three-point formula with optimistic = 80, most likely = 100, pessimistic = 150, what is the expected duration?

A.105.0

B.108.3

C.110.0

D.112.5

Explanation: The PERT mean is (O + 4M + P) / 6 = (80 + 4(100) + 150) / 6 = (80 + 400 + 150) / 6 = 630 / 6 = 105.0. PERT weights the most likely value 4x to capture the influence of the modal estimate.

6On the AACE CEP exam, an estimator builds up a project total by quantifying every work package, applying unit rates, and summing the result. This is best described as which method?

A.Top-down estimating

B.Analogous estimating

C.Bottom-up (detailed/definitive) estimating

D.Order-of-magnitude estimating

Explanation: Bottom-up (also called detailed or definitive) estimating decomposes the scope into work packages, quantifies each (QTO/MTO), applies unit rates and crew productivities, and sums. It supports Class 1/2 estimates and is the most accurate but most labor-intensive method.

7Per AACE RP 18R-97, what is the typical primary characteristic that distinguishes estimate classes from each other?

A.Currency used

B.Level of project definition

C.Number of estimators on the team

D.Whether escalation is included

Explanation: RP 18R-97 explicitly identifies the level of project definition (engineering deliverables completed) as the primary characteristic — the X-axis of the classification matrix. Secondary characteristics include end usage, methodology, accuracy range, and effort.

8A project has BAC = $1,000,000, EV = $400,000, and AC = $500,000. What is the Cost Performance Index (CPI)?

A.0.80

B.1.25

C.0.50

D.1.20

Explanation: CPI = EV / AC = 400,000 / 500,000 = 0.80. A CPI below 1.0 indicates the project is over budget — for every $1 spent, only $0.80 of value has been earned.

9Given BAC = $2,000,000 and CPI = 0.80, what is the Estimate at Completion (EAC) using the most common formula that assumes the current cost performance continues?

A.$1,600,000

B.$2,500,000

C.$2,000,000

D.$1,250,000

Explanation: EAC = BAC / CPI = 2,000,000 / 0.80 = $2,500,000. This is the standard EVA formula when the team expects past cost variance to persist for the remaining work.

10Per AACE RP 40R-08 (Contingency Estimating — General Principles), contingency is intended to cover which of the following?

A.Scope changes outside the current project definition

B.Costs that are likely to occur due to uncertainties within the defined scope

C.Profit margin for the contractor

D.Owner-directed schedule acceleration

Explanation: RP 40R-08 defines contingency as an amount added to a base estimate to cover items, conditions, or events that are likely (>50% probable in aggregate) to add cost but cannot be specifically identified at the time of the estimate. It is for in-scope uncertainty, not for scope growth, profit, or owner-directed changes.

AACE CEP Certified Estimating Professional Study Tips from Top Performers

1Master AACE Recommended Practices: 17R-97, 18R-97, 47R-11, 56R-08 (estimate classification by industry); 40R-08 and 41R-08 (contingency and range estimating); 67R-11 (estimating); 25R-03 and 31R-03 (productivity).

2Memorize EVA formulas: CPI = EV/AC, SPI = EV/PV, EAC = BAC/CPI, ETC = EAC − AC, VAC = BAC − EAC.

3Practice the PERT three-point formula: Mean = (O + 4M + P) / 6.

4Know the capacity-factored estimate exponent: Cost2 = Cost1 x (Cap2/Cap1)^n, with the six-tenths rule (n=0.6) as the most common default.

5Draft and refine your technical paper early — many candidates underestimate this requirement.
