The purpose of this study was two-fold: (1) to analyse the psychometric properties of the Spanish version of the first part of the "Tool for Assessing Responsibility-based Education (TARE)" that we have called instrumento de observación de las estrategias de los profesores para enseñar responsabilidad; (2) to analyse the strategies used by 4 physical education teachers in their classes. The results revealed, on the one hand, that the validity and reliability of the Spanish version of the TARE were satisfactory. On the other hand, the four teachers showed strategies that fostered respect and gave all the students opportunities for success. Additionally, differences in teachers' strategies for giving students choices and voices were found. Nevertheless, teachers did not use many strategies for fostering students' autonomy and leadership. Thus, all teachers showed low use of strategies for fostering students' role in assessing their own learning and transferring to other contexts.
