Section 1: Regulations, Licensing, and Administrative Rules
Question 1
Which Texas Administrative Code chapter contains the rules governing landscape
irrigation?
A) 30 TAC Chapter 290
B) 30 TAC Chapter 344
C) 30 TAC Chapter 210
D) 30 TAC Chapter 285
Correct Answer: B
Rationale: 30 Texas Administrative Code (TAC) Chapter 344 contains the
rules, regulations, and statutes for licensed irrigators in Texas. This chapter
establishes the minimum standards for landscape irrigation design, installation,
and operation. Chapter 290 addresses public drinking water, Chapter 210
addresses sludge, and Chapter 285 addresses on-site sewage facilities. These are
unrelated to landscape irrigation regulation.
Question 2
What is the minimum passing score required for each section of the Texas
Landscape Irrigator examination?
A) 60%
B) 65%
C) 70%
D) 75%
Correct Answer: C
, Rationale: Per 30 TAC §30.120, the minimum passing score for each
section of the Texas Landscape Irrigator examination is 70 percent. If an applicant
fails a section, they must retest on that specific section. This standard applies to
all TCEQ occupational licensing examinations, including Landscape Irrigator,
Irrigation Technician, and Irrigation Inspector.
Question 3
Under Texas Occupations Code Chapter 1903, which of the following individuals is
exempt from landscape irrigator licensing requirements?
A) A person who designs an irrigation system for a commercial property
B) A property owner performing irrigation work on premises occupied as their
home
C) A person who installs irrigation systems for a landscaping company
D) A person who consults on irrigation system design for municipal parks
Correct Answer: B
Rationale: Texas Occupations Code §1903.002(c)(1) explicitly exempts
irrigation or yard sprinkler work performed by a property owner in a building or
on premises owned or occupied by the person as their home. This exemption
does not apply to commercial properties, for-profit installation work, or
consultation services for public entities. The exemption is specifically designed to
allow homeowners to work on their own residential irrigation systems without
licensure.
Question 4
How many hours of approved training credits must a licensed irrigator complete
to renew their license?
A) 8 hours
B) 16 hours
C) 24 hours
D) 32 hours
, Correct Answer: C
Rationale: Per 30 TAC §30.122, a licensed irrigator must complete 24
hours of approved training credits (continuing education) to renew their license.
This requirement was increased from the previous 16 hours. The training must be
job-related and approved by the executive director. Licenses are valid for three
years from the date of issuance, meaning 24 hours must be completed within
each three-year cycle.
Question 5 (SATA)
Which of the following are responsibilities of a TCEQ-licensed Irrigation Inspector?
Select all that apply.
A) Verifying that permits have been obtained
B) Inspecting irrigation systems for compliance with rule requirements
C) Designing irrigation systems for commercial properties
D) Determining if the appropriate backflow prevention device is installed
E) Providing test results to the water purveyor
F) Installing backflow prevention assemblies
Correct Answers: A, B, D, E
Rationale: Per TCEQ licensing definitions, an Irrigation Inspector is
responsible for verifying that permits have been obtained, inspecting the
irrigation system to determine compliance with rule requirements, determining if
the appropriate backflow prevention device is installed, providing test results to
the water purveyor, and investigating complaints. Irrigation Inspectors do not
design systems (that is the role of a Landscape Irrigator) and do not install
backflow assemblies (that is the role of an Irrigation Technician under supervision
or a Licensed Irrigator). These distinctions are critical for understanding the scope
of practice for each license type.
Question 6
Who administers the Landscape Irrigator examination on behalf of the TCEQ?
, A) Texas Department of Licensing and Regulation (TDLR)
B) Texas A&M AgriLife Extension Service
C) Texas Engineering Extension Service (TEEX)
D) Texas State Board of Plumbing Examiners
Correct Answer: C
Rationale: The TEEX (Texas Engineering Extension Service) administers the
Landscape Irrigator examination on behalf of the Texas Commission on
Environmental Quality (TCEQ). TEEX is part of The Texas A&M University System
and provides occupational licensing exams for multiple state agencies. TDLR
handles other occupational licenses but not landscape irrigation. The Texas State
Board of Plumbing Examiners handles plumbing licenses, which are separate from
irrigation licensing.
Question 7
What is the fee for a TCEQ Landscape Irrigator license application?
A) $75
B) $100
C) $111
D) $150
Correct Answer: C
Rationale: Per TCEQ licensing requirements, the application fee for a
Landscape Irrigator license is $111. This fee covers the application processing and
is submitted along with the TCEQ application, criminal history attestation, and
proof of completion of the Basic Irrigator Licensing Course. The fee is separate
from any examination fees charged by TEEX or computer-based testing centers.
Question 8
A licensed irrigator must obtain a seal upon being licensed. What is the purpose
of this seal?
