Observe, coach, and document trainee performance without independently authorizing clinical practice; final organizational competency validation is completed by designated qualified nursing leadership or another authorized clinical evaluator, and practitioner orders, delegation, and supervision required by state law remain separate requirements; in California, nursing sign-off does not replace the supervising physician's or podiatrist's responsibilities under 16 CCR § 1366.3 (see California Scope of Practice). Train other medical assistants in technical supportive services only when qualified and authorized under applicable state law, including California Business and Professions Code §§ 2069–2071 and 16 CCR §§ 1366–1366.4, and clinic policy; medical assistants serving as clinical trainers must maintain applicable certification, demonstrated proficiency, and any additional qualifications required for the procedure being taught.
