CERTIFICATION & TRAINING RULE UPDATES Original
Questions with Answers and Rationales
Section 1: Unlicensed Supervision Requirements (Questions)
1. Under the 2026 EPA federal competency standards, when
may a certified applicator supervise a non-certified handler
using a Restricted Use Pesticide (RUP)?
A. The non-certified handler may work alone after one
training session
B. The certified applicator must provide direct, site-specific
instructions and maintain a direct means of immediate
communication with the non-certified handler
C. The non-certified handler may work without any
supervision once hired
D. The certified applicator only needs to be available by
phone at the end of the day
Answer: B
Rationale: The 2026 EPA competency standards require
certified applicators supervising non-certified handlers
using RUPs to provide direct, site-specific instructions and
maintain a direct means of immediate communication
(e.g., phone, radio, or visual contact) at all times during

2. What does "direct, site-specific instructions" mean under
the 2026 C&T Rule?
A. General instructions given once at the beginning of the
season
B. Instructions tailored to the specific application site,
including the pesticide, target pest, application rate, safety
precautions, and site-specific hazards
C. Written instructions posted on a bulletin board only
D. Verbal instructions given only in English
Answer: B
Rationale: Direct, site-specific instructions are detailed
guidance for the specific application at the specific site,
covering the pesticide being used, application rate, target
pest, safety requirements, PPE, and site-specific hazards
(e.g., nearby water, sensitive areas).
3. What is a "direct means of immediate communication"
under the 2026 C&T Rule?
A. A letter sent by mail
B. A phone, radio, or other electronic device allowing the
certified applicator and non-certified handler to
communicate in real-time during the application
C. A note left at the site
D. A scheduled check-in at the end of the day
Answer: B
Rationale: Direct means of immediate communication
, https://www.stuvia.com/user/performance
requires real-time two-way communication capability
(e.g., cell phone, two-way radio, or visual/voice contact)
so the certified applicator can provide guidance or stop
the application immediately if needed.
4. Under the 2026 C&T Rule, can a certified applicator
supervise a non-certified handler who is applying RUPs at a
different location several miles away?
A. Yes, if the certified applicator is available by phone
B. No, the certified applicator must be at the application
site or in close proximity with direct communication and
the ability to intervene if necessary
C. Yes, if the handler has completed training
D. Yes, if the handler has worked for more than one year
Answer: B
Rationale: The 2026 rule requires the certified applicator
to be at the application site or in close enough proximity
to provide direct supervision and intervene if needed.
Remote supervision by phone alone is not sufficient for
RUP applications.
5. What is the purpose of the 2026 EPA competency
standards for supervision of non-certified handlers?
A. To reduce supervision requirements
B. To ensure non-certified handlers using RUPs receive
adequate oversight to prevent misuse, drift, and exposure
