Introduction
This comprehensive assessment is designed to prepare candidates for the Illinois Architect Registration
Examination by simulating the breadth, depth, and decision-making demands of the actual licensure test. It
measures foundational theory, applied technical knowledge, regulatory compliance, ethics, and professional
judgment across real-world scenarios. Each multiple-choice question integrates critical thinking with practice-
,based challenges, from site analysis to contract administration. Emphasis is placed on Illinois-specific legal
frameworks, the Illinois Accessibility Code, and standard industry contracts. All answers are verified, with rationales
provided to reinforce learning and defensible reasoning for exam success.
SECTION ONE: QUESTIONS 1–100
Question 1
A design professional is retained for a commercial project in Chicago. The owner refuses to commission a
geotechnical report despite the architect’s recommendation. The architect proceeds with foundation design
based on adjacent property data. Later, differential settlement causes structural damage. Who bears primary
liability?
A. The general contractor for failing to verify soil conditions
B. The architect for proceeding without adequate site investigation
C. The owner for refusing to authorize the geotechnical report
D. The structural engineer of record for not demanding the report
🟢B
🔴 RATIONALE: Architects have a professional duty to obtain sufficient site data before designing. Proceeding
without a geotechnical report against the owner’s refusal does not fully relieve the architect of liability if a
reasonable architect would have withdrawn or insisted further. Owner refusal is a factor but does not
automatically shift all liability.
Question 2
,Under the Illinois Architecture Practice Act of 1989, which activity is exclusively reserved for a licensed architect?
A. Drafting interior elevation details for a single-family home
B. Preparing construction documents for a new 10,000 sq ft retail strip mall
C. Supervising a mechanical subcontractor’s installation
D. Conducting an energy model analysis for code compliance
🟢B
🔴 RATIONALE: The Illinois Act requires architectural licensure for preparing construction documents for
buildings with human occupancy exceeding certain thresholds, including commercial retail over 5,000 sq ft.
Drafting residential interiors is exempt; supervision and energy modeling do not require architectural licensure.
Question 3
An architect specifies a green roof system. During construction, the contractor proposes substituting a less
expensive extensive green roof without changing the structural load. The architect’s first responsibility is to:
A. Approve the substitution immediately to save client money
B. Verify that the substitution meets all performance specifications and warranties
C. Issue a change order without additional documentation
D. Require the contractor to assume full liability for the substitution
🟢B
🔴 RATIONALE: The architect must ensure any substitution meets or exceeds original performance criteria,
including durability, drainage, and thermal performance. Cost savings alone do not justify acceptance without
technical verification.
Question 4
, Which document typically establishes the architect’s right to terminate the agreement for cause if the owner
fails to make payments?
A. AIA A201 General Conditions
B. AIA B101 Standard Form of Agreement Between Owner and Architect
C. AIA A101 Standard Form of Agreement Between Owner and Contractor
D. AIA C401 Standard Form of Agreement Between Architect and Consultant
🟢B
🔴 RATIONALE: AIA B101 includes specific provisions allowing the architect to terminate the agreement if the
owner fails to make payments after notice. A201 is between owner and contractor, not directly addressing
architect-owner termination.
Question 5
During construction observation, the architect notices that fire-rated shaft wall assemblies are missing required
sealant at penetration joints. The contractor claims it is not in the approved submittals. What should the
architect do first?
A. Accept the installation and note it in the punch list
B. Issue a non-conformance report and require correction per code
C. Ask the owner if they want to accept the condition
D. Revise the drawings retroactively to match as-built conditions
🟢B
🔴 RATIONALE: Life safety is non-negotiable. The architect must enforce code compliance regardless of
