Physical Education (PE) teachers' professional and personal skills may not only affect the quality of the teaching-learning processes in PE, but also individuals' future active/inactive behaviors. The aim of this study is to examine the structure of a pool of items developed for measuring individuals' perception of such skills in PE teachers. Exploratory Factorial Analysis and a following structural modeling test on data collected from 660 participants suggest a two-factor structural model for the 10 items considered (χ2 = 191.155; df = 34; CFI = 0.953, and SRMR = 0.0529), with good internal consistency for both factors (factor 1: alpha = 0.879; omega = 0.878; factor 2: alpha = 0.850, and omega = 0.858) and the overall instrument (alpha = 0.892; omega = 0.895). The final "Teachers' Personal and Professional Skills Questionnaire" is a valid instrument that may be used alone or in combination with other instruments for the analysis of the quality of teaching-learning processes in PE environments and its impact on individuals' behaviors regarding physical activity in their adult life.
