The correct answer emphasizes that the employer retains the certification responsibility even when utilizing external services for Level III certification. This is crucial in maintaining the integrity and quality of the certification process. While external services may provide support, such as training or testing, the ultimate responsibility for ensuring that the certification meets the necessary standards and reflects the competence of the individual lies with the employer. This means that the employer must ensure that all procedures are followed correctly and that the certification is not only appropriate but also beneficial to the organization.

Involving external services does not absolve the employer of this responsibility; rather, it is part of a collaborative effort where the employer must verify that all aspects of the certification process align with industry standards and their own requirements. Ultimately, this ensures that the personnel certified under their watch are capable and reliable, maintaining safety and operational standards within their organization.
