Which of the following best describes a significant predictor of perceived competence in supervision?

Satisfaction with supervision is a significant predictor of perceived competence in supervision because it reflects the quality of the supervisory relationship and the effectiveness with which supervisors engage their staff. When supervisees feel satisfied with their supervision experience, it often correlates with a perception that the supervisor is competent, supportive, and capable of providing the guidance needed for professional growth. Moreover, satisfaction can enhance trust and open communication, which are vital components of a strong supervisory dynamic.

The other options address different aspects of the supervision process but do not directly relate to the supervisee's perception of the supervisor's competence. Clinical credentialing pertains to the qualifications and certifications of the supervisor, which, while important, does not automatically equate to how competent a supervisee perceives their supervisor to be. Staff turnover rates can reflect various organizational issues but do not provide insight into the specific supervisory competence perceived by individuals. Observational assessments might be useful tools for evaluating supervision outcomes but do not directly measure satisfaction or perceived competence. Thus, satisfaction with supervision stands out as the most relevant factor in assessing perceived competence.
