Improving the quality of higher education in D.R. Congo and in Several countries in the world is currently the priority objective fixed in different educative policies. Due to attention given to this question by those who seek effectiveness of higher education, we have evaluated the quality of teaching thanks to achieved performances of students by resorting to experimental approach. In this regard, we have compared the results of two thousand and twenty two (2022) students in ten promotions who have been submitted to pre-test and post-test. Considering students performances during pre-test and post-test, all the promotions are superior to 0,15. Nevertheless, students’ performances during post-test are superior to those of pre-test.
