Section 1: COR Roles & Responsibilities (10 Questions)
Q1: A contractor approaches the COR during site visits and frequently requests informal
approval for minor changes to work procedures. The COR believes these changes will improve
efficiency without affecting cost or schedule. What should the COR do?
A. Approve the changes verbally to maintain good relations, then document them in the next
report to the KO
B. Direct the contractor to proceed with the changes and include them in the next contract
modification
C. Inform the contractor that only the Contracting Officer has authority to approve changes, and
relay the request to the KO [CORRECT]
D. Approve the changes if they are under $2,500 to stay within micro-purchase thresholds
Correct Answer: C
Rationale: Under FAR 1.602-2(d), the Contracting Officer is the only government official with
authority to enter into, administer, and terminate contracts. The COR acts as the KO's
representative for technical monitoring but cannot change contract terms or direct work outside
the contract scope (FAR 1.602-2(d)(2)). Option A is incorrect because verbal approvals constitute
a constructive change. Option B exceeds COR authority. Option D confuses procurement
thresholds with contract modification authority.
Q2: The COR appointment letter must specify all of the following EXCEPT:
A. The scope of the COR's authority and specific duties delegated
B. The dollar threshold for modifications the COR may approve
C. The period of appointment and limitations of authority
D. The COR's relationship to the Contracting Officer and communication protocols
Correct Answer: B
,2
Rationale: Per FAR 1.602-2(d)(2), the COR appointment letter must include the scope of
authority, duties, limitations, period of appointment, and relationship with the KO. However,
CORs have no authority to approve modifications regardless of dollar amount—only the KO can
issue contract modifications (FAR 43.102). Option B represents a common misconception about
COR authority limits. The appointment letter should explicitly state that the COR cannot approve
modifications.
Q3: During a post-award conference, the contractor asks the COR to clarify technical
requirements in the Performance Work Statement (PWS). The COR notices the PWS contains
ambiguous language that could lead to disputes. What is the COR's appropriate action?
A. Interpret the requirement for the contractor based on the government's intent
B. Request the KO issue a clarification or modification to address the ambiguity [CORRECT]
C. Direct the contractor to follow the most conservative interpretation to avoid risk
D. Inform the contractor that ambiguity benefits the government under the Christian doctrine
Correct Answer: B
Rationale: When the COR identifies ambiguous contract language, they must communicate this
to the KO (FAR 1.602-2(d)(2)). Only the KO can issue clarifications or modifications (FAR
43.102). Option A risks creating a constructive change or unauthorized commitment. Option C
constitutes directing the contractor, which exceeds COR authority. Option D misapplies legal
doctrine—the Christian doctrine applies to mandatory FAR clauses, not interpretive ambiguity.
Q4: A COR is appointed to a cost-plus-fixed-fee (CPFF) R&D contract. Which additional
responsibility is MOST likely required compared to a firm-fixed-price (FFP) contract?
A. Reviewing and validating the contractor's indirect cost rates
B. Monitoring contractor compliance with Cost Accounting Standards [CORRECT]
C. Conducting 100% inspection of all deliverables
D. Negotiating fee adjustments based on performance
Correct Answer: B
Rationale: Cost-reimbursement contracts require heightened oversight of cost allowability and
accounting practices (FAR 42.705). The COR must monitor compliance with Cost Accounting
Standards (CAS) and ensure costs are allowable, allocable, and reasonable (FAR 31.201-2).
Option A involves the cognizant federal agency, not the COR. Option C is inefficient and not
required by contract type. Option D exceeds COR authority—fee determination is the KO's
responsibility.

Q5: The project manager (PM) directs the COR to expedite a critical deliverable by instructing
the contractor to work overtime. The COR knows the contract does not include overtime
premium funding. What should the COR do?
A. Follow the PM's direction as the senior technical authority
B. Instruct the contractor to work overtime and bill at standard rates
C. Advise the PM that overtime requires KO approval and may need a modification [CORRECT]
D. Authorize the overtime verbally and document it as a constructive change later
Correct Answer: C
Rationale: Directing overtime work outside contract terms constitutes a constructive change
(FAR 43.101). The COR must advise the PM that such direction exceeds their authority and
requires KO action (FAR 1.602-2(d)(2)). Options A, B, and D all result in unauthorized
commitments or constructive changes that could expose the government to claims. The COR
serves as the technical liaison, not the contracting authority.
Q6: Which scenario represents a COR exceeding their delegated authority?
A. Rejecting non-conforming supplies and documenting the rejection in the contract file
B. Conducting quality assurance surveillance per the QASP and reporting results to the KO
C. Informing the contractor that the government will not pay for work outside the contract scope
D. Telling the contractor to stop work immediately due to safety violations [CORRECT]
Correct Answer: D
Rationale: While safety violations are serious, directing the contractor to stop work constitutes a
suspension of work, which requires KO authority under the Suspension of Work clause (FAR
52.242-14). The COR must immediately notify the KO of safety issues but cannot direct work
stoppage. Options A, B, and C are within COR authority—rejecting non-conforming items (FAR
46.407), conducting surveillance (FAR 46.401), and clarifying payment limitations are proper
COR functions.
Q7: Under DAWIA and FAC-COR certification requirements, a Level II COR typically requires:
A. 1 year of experience and 40 hours of training
B. 2 years of experience and 80 hours of training [CORRECT]
C. 3 years of experience and 120 hours of training
D. 5 years of experience and 160 hours of training
Correct Answer: B
