Developing Competencies and Milestones: Putting the Pieces Together for Student Success.

Competency-based medical education has become a means in physician assistant (PA) education to ensure learner readiness for practice; align educational expectations; and assess knowledge, skills, and attitudes. Competency-based education may also serve to meet accreditation requirements. Creating program-defined competencies and associated milestones can help a PA program align with their mission and vision, developmentally guide learners through the curriculum, and ensure program assessments measure the tasks required of practice-ready graduates.

Cross-species experiments reveal widespread cochlear neural damage in normal hearing.

Animal models suggest that cochlear afferent nerve endings may be more vulnerable than sensory hair cells to damage from acoustic overexposure and aging. Because neural degeneration without hair-cell loss cannot be detected in standard clinical audiometry, whether such damage occurs in humans is hotly debated. Here, we address this debate through co-ordinated experiments in at-risk humans and a wild-type chinchilla model.
