The amount of students who want to study technical sciences significantly reduces in Latvia, as in whole Europe. In the same way, the level of students’ knowledge in science subjects also reduces, as a result of which, the amount of deducted students increase. That is why it is important to realize problems students have during the study process, and solve them by improving the teaching quality of the subject. Students’ questionnaires help detecting these problems. Study department of Riga Technical University (RTU) in cooperation with the Department of Information Technologies have created the system of students' survey, not less than once a semester carrying out surveys for students about the quality of the content of the studies of mathematics and teaching forces. Using port ORTUS, every student receives a survey about every subject acquired during the semester. Surveys are anonymous and are not personally connected with every particular student; gained results are significant for the improvement of the quality of the studies. Students’ questionnaires about the teaching staff of the RTU Department of Engineering Mathematics indicate that in general lecturers of the department work well. If students’ questionnaires indicate any problems in the content of mathematical subjects or teaching methods, the problem is being solved inside the department.
