The inclusion of students in the assessment process is a vital and essential part of the process

of evaluation. This kind of method is integrated with learning or teaching and when students

evaluate their own performances, the responsibility for the level and quality of their learning

remains more in them than the teacher. Self-assesment can improve the efficiency of

learning. It helps in developing the ability to analyze and form critical attitudes towards the

learning process. Self-assessment offers an opportunity for students to undertake the

responsibility for their own learning and it also contributes to giving a more pronounced

sense of ownership of what they learn. The aim of the research was to investigate whether

teachers give priority to self-assessment as an important tool for the teacher’s formative

assessment. Several methods were used: inductive, deductive, comparative and a statistical

method. The data collection instrument was a questionnaire for teachers, and a questionnaire

for students.120 teachers and indicate that this process makes students more independent in

the way they learn and take responsibility for their learning.
