Determination of psychometric indices of the Polish language version of the Student Satisfaction and Self Confidence in Learning Scale (SSCL). The validity of the research conducted is significant, the scale of the SSCL will be the first tool in Poland, thanks to which the possibility will be created to monitor the didactic process in which the high-fidelity simulation method is used. Construct validity was tested using the following Confirmatory Factor Analysis (CFA fit index is 0.52) and Exploratory Factor Analysis (EFA explains 48.3% of the variance). Cronbach’s alpha-coefficient was used to assess the internal consistency of the scale. The Cronbach’s Alpha coefficient for the scale as a whole was 0.90, for the subscale “Satisfaction with current learning” was 0.87; for the subscale “Self-confidence in learning” was 0.84. As the study showed, the simulation of high-fidelity positively affects students’ satisfaction and increases their confidence levels.
