Certification Skill Checks are administered by the trainee's ___.

• A. OS
• B. Hub Manager
• C. Training team
• D. OJTI

Answer: (A)

Certification Skill Checks measure whether a trainee can perform key operational tasks correctly and safely in real working conditions. The person who administers these checks is the supervisor responsible for the trainee’s day-to-day work and safety—the operating supervisor. This role directly observes performance, provides immediate feedback, and signs off when the trainee demonstrates the required competence, tying the evaluation to actual job standards. A hub manager oversees broader operations and isn’t typically the one who certifies day-to-day task performance; the training team may deliver instruction but doesn’t usually certify live-work competence; the OJTI guides on-the-job training, but the formal sign-off for these checks generally comes from the trainee’s OS.
