An Authorized Assistant may supervise a maximum of 2 non-certified assistants, or 6 if performing single stem basal treatment.

• A. 3 non-certified assistants in all cases.
• B. 6 non-certified assistants in all cases.
• C. 2, with no exceptions.
• D. 2, or up to 6 if performing single stem basal treatment.

Answer: (D)

The main idea being tested is how many non-certified assistants an Authorized Assistant may supervise under Alberta pesticide rules, and when an exception applies. Normally, an Authorized Assistant may supervise up to two non-certified assistants. However, if performing a single stem basal treatment, the limit can be increased to six non-certified assistants. So the correct statement captures both parts: two, with the option to supervise up to six in the special case of a single stem basal treatment. The other options either set a higher limit in all cases or deny the exception, which doesn’t align with the regulatory allowance.
