SECTION 1: LICENSING & REGULATORY FRAMEWORK (Questions 1–40)
Question 1
Which Virginia agency regulates Electronic/Communication Service (ESC) contractors?
A) Virginia Department of Environmental Quality
B) Virginia Department of Professional and Occupational Regulation (DPOR)
C) Virginia Department of Transportation
D) Virginia State Corporation Commission
Answer: B) Virginia Department of Professional and Occupational Regulation (DPOR)
Rationale: The Virginia Department of Professional and Occupational Regulation (DPOR),
through its Board for Contractors, regulates ESC contractors under Virginia Code § 54.1-
,1100 et seq. DPOR administers licensing, approves pre-licensing courses, and enforces
contractor regulations.
Question 2
What is the maximum voltage permitted for systems installed under the Virginia ESC
specialty license?
A) 24 volts
B) 50 volts
C) 120 volts
D) 240 volts
Answer: B) 50 volts
Rationale: The Virginia ESC specialty specifically governs low-voltage systems operating at
50 volts or less. This includes telephone wiring, computer cabling, sound systems, data
links, fiber optics, and cable TV wiring. Work exceeding 50 volts requires a separate
electrical (ELE) classification.
Question 3
What is the minimum experience requirement for a Virginia ESC contractor license?
A) 1 year
B) 2 years
C) 3 years
D) 5 years
Answer: B) 2 years
, Rationale: Individual applicants for an ESC license in Virginia must have a minimum of two
years of experience in the trade or equivalent education and training. The experience must
be documented and verifiable.
Question 4
What is the minimum net worth or surety bond requirement for a Class C ESC contractor in
Virginia?
A) $10,000
B) $15,000
C) $25,000
D) $45,000
Answer: B) $15,000
Rationale: A Virginia Class C ESC contractor must maintain a minimum net worth or surety
bond of $15,000. This financial requirement ensures that the contractor has the resources to
fulfill obligations to clients and suppliers.
Question 5
What is the maximum contract value for a Class C ESC contractor in Virginia?
A) $10,000 per contract
B) $25,000 per contract
C) $50,000 per contract
D) $500,000 per contract
Answer: A) $10,000 per contract
