Validity and reliability of the academic performance scale from the student’s perception

The academic performance was evaluated from the aptitude of the students, in this line of research work has been developed in different areas that have the limitation to access instruments that evaluate academic performance from the perception of the student. This research aimed to analyze the validity and reliability of the academic performance scale from the student’s perception, according to the perspective of students in private universities in Peru. For this purpose, an instrumental design was used, with a sample of 282 students selected by means of a non-probabilistic sampling by criteria. The comparative fit indices presented acceptable values (CFI, 0.97; TLI, 0.97), the goodness-of-fit indices are also acceptable (RMSEA, 0.088; SRMR, 0.072), the factorial analysis has only validated 18 items with the three dimensions; reliability has presented values higher than 0.80. Therefore, it is concluded that the scale can be used as a comprehensive diagnostic and evaluation tool, to improve the study habits of students, and rethink new teaching strategies considering the needs of teachers.
