The purpose of this study was to describe the differences of teachers with and without National Board Certification in relation to their percentages of student competency in high school physical education. Data from the South Carolina Physical Education Assessment Program (SCPEAP) were used as the measure of student competency. Student competency was measured on motor skill performance, cognitive fitness knowledge, outside-of-class participation, and health-related fitness levels. A total weighted student competency score was calculated by a linear combination of scores. The results were analyzed descriptively. Mean differences were identified in student competence between National Board Certified Teachers (NBCTs) and non-NBCTs. NBCTs were stronger on all four performance indicators and on the overall measure of student competency.
