INTRODUCTION
The NASCLA Construction Scheduling Exam is a highly specialized, rigorous professional
assessment designed to evaluate a candidate’s mastery of advanced project planning,
scheduling methodologies, resource allocation, and time-risk management within the
commercial and residential construction sectors. Administered by the National Association
of State Contractors Licensing Agencies (NASCLA), this examination serves as a critical
benchmark for project managers, scheduling engineers, and general contractors seeking
multi-state licensing or advanced credentials.
Navigating this assessment requires a fluent, highly precise understanding of the Critical
Path Method (CPM), Precedence Diagramming Method (PDM), resource leveling algorithms,
cost-loading parameters, and delay analysis frameworks (such as the windows method and
time impact analysis). This practice package is specifically engineered to mirror the analytical
and application-level complexity of the actual exam. By mastering these scenario-based
problems and studying their detailed rationales, candidates will bridge critical knowledge
deficits and develop the diagnostic decision-making skills required to pass the NASCLA exam
definitively on their first attempt.
CORE DOMAINS TESTED
• Domain 1: Pre-Construction Planning and Logic Development – Focuses on Work
Breakdown Structures (WBS), determining activity relationships (Finish-to-Start,
Start-to-Start, etc.), and establishing realistic durations.
• Domain 2: Network Calculations and Critical Path Method (CPM) – Evaluates
forward and backward pass calculations, identifying early/late start and finish dates,
and calculating total and free float.
• Domain 3: Resource Allocations and Leveling – Concentrates on resource loading,
resolving manpower or equipment constraints, and analyzing the impact of leveling
on the project completion date.
• Domain 4: Project Monitoring, Updating, and Cost Control – Targets progress
tracking strategies, Earned Value Management (EVM) metrics (CV, SV, CPI, SPI), and
updating logic baselines.

• Domain 5: Delay Analysis and Contractual Schedules – Assesses time impact
analysis, excusable vs. non-excusable delays, acceleration strategies (crashing/fast-
tracking), and liquidated damages implications.
Q1: A commercial construction project schedule indicates that
Activity G (Install Interior Drywall) has an Early Start (ES) of Day 45, a
Late Start (LS) of Day 52, an Early Finish (EF) of Day 60, and a Late
Finish (LF) of Day 67. The immediate succeeding activity, Activity H
(Prime and Paint Walls), has an Early Start of Day 64. What is the
Total Float and Free Float for Activity G?
A) Total Float = 0 days; Free Float = 0 days
B) Total Float = 7 days; Free Float = 7 days
C) Total Float = 7 days; Free Float = 4 days
D) Total Float = 12 days; Free Float = 4 days
Rationale: The correct answer is C because Total Float is calculated as
either Late Start minus Early Start (52 - 45 = 7) or Late Finish minus
Early Finish (67 - 60 = 7). Free Float is the amount of time an activity
can be delayed without delaying the Early Start of any immediate
successor activity, calculated as ES of successor minus EF of current
activity (64 - 60 = 4). Options A, B, and D are mathematically
incorrect based on standard CPM network logic.
Q2: A general contractor is evaluating a schedule constraint where
the structural steel delivery requires a 14-day lead time after
fabrication is complete before erection can begin. In a Precedence
Diagramming Method (PDM) network diagram, how should this 14-
day duration be represented between the "Fabricate Structural Steel"
and "Erect Structural Steel" activities?
A) As a negative float constraint on the driving stack.
B) As a 14-day lag on a Finish-to-Start (FS) relationship.
C) As a 14-day lead on a Start-to-Start (SS) relationship.
D) As a mandatory milestone constraint with an external finish gate.
Rationale: The correct answer is B because a lag is a modification of a
,3
logical relationship that directs a delay in the successor activity. A 14-
day delay after the finish of fabrication before erection can start is
accurately modeled as a Finish-to-Start relationship with a 14-day lag
(FS + 14). Option A is incorrect because float is calculated, not
assigned as a constraint. Option C is incorrect because a lead
represents an acceleration (negative lag). Option D is incorrect
because milestones have zero duration and do not represent
continuous waiting paths.
Q3: During a resource leveling evaluation for a multi-story concrete
pour, the scheduling engineer restricts the maximum daily concrete
finishing crew allocation to 12 workers. If a non-critical activity
requires 16 workers over its 5-day duration and has 8 days of Total
Float, what will be the most likely impact of applying resource
leveling to this specific activity?
A) The activity will be completed ahead of schedule by compressing
its logic.
B) The activity's duration will extend or its start date will be
delayed, consuming some or all of its total float without extending
the project end date.
C) The project's critical path will immediately shorten by 3 days.
D) The activity must be permanently deleted from the Work
Breakdown Structure.
Rationale: The correct answer is B because resource leveling delays
activities or extends durations to fit within resource limits. Since this
activity is non-critical and possesses 8 days of Total Float, it can
absorb a delay or extension caused by the 12-worker crew cap
without shifting the final project completion date. Option A is
incorrect because resource constraints extend or delay schedules
rather than compress them. Option C is incorrect because leveling
, 4
non-critical paths does not automatically shorten the critical path.
Option D is an invalid administrative action.
Q4: A project schedule update indicates that a project has an Earned
Value (EV) of $450,000, a Planned Value (PV) of $500,000, and an
Actual Cost (AC) of $480,000. What is the Schedule Variance (SV) and
Cost Variance (CV) for this project?
A) SV = +$50,000; CV = +$30,000
B) SV = -$50,000; CV = -$30,000
C) SV = -$30,000; CV = -$50,000
D) SV = +$20,000; CV = -$30,000
Rationale: The correct answer is B because Schedule Variance is
calculated as EV minus PV ($450,000 - $500,000 = -$50,000), which
indicates the project is behind schedule. Cost Variance is calculated as
EV minus AC ($450,000 - $480,000 = -$30,000), which indicates the
project is over budget. Options A, C, and D utilize inverted formulas or
incorrect values.
Q5: A project manager needs to compress a construction schedule to
meet a liquidated damages milestone. The cost to crash Activity X
(Critical) is $1,200 per day for a maximum of 4 days. The cost to crash
Activity Y (Critical) is $900 per day for a maximum of 3 days. The cost
to crash Activity Z (Non-critical) is $600 per day for a maximum of 5
days. To achieve a total schedule compression of 3 days at the lowest
possible cost, what crashing sequence must be selected?
A) Crash Activity Z for 3 days at a total cost of $1,800.
B) Crash Activity Y for 3 days at a total cost of $2,700.
C) Crash Activity X for 3 days at a total cost of $3,600.
D) Crash Activity X for 1 day and Activity Y for 2 days at a total cost of
$3,000.
Rationale: The correct answer is B because crashing must target
critical path activities to shorten the project duration. Activity Y is
