The process of continuous monitoring, examining and evaluating students and their progress is an integral part of each educational process. Through this process, teachers are trying to gather different elements about students to evaluate students' achievements more objectively and more realistically. Students are most likely to be examined by oral and written examination, since teachers can get the most amount of feedback in these ways, that is, in a minimal amount of time, they can examine a large number of students. The assessment process is the hardest part for teachers. This study included elementary and secondary schools teachers from Metković and Zadar and for the purposes of this study a questionnaire with 34 questions of open and closed type was used. The results of the study show that all the teachers regularly monitor their students and that oral and written ways of examination are the most commonly used, that is, preferred forms of checking student’s knowledge. Through oral examination, teachers receive the most feedback from their students. Also, the results show that grading students is the most difficult part of teacher’s work because it is not always possible to be completely objective. The same number of respondents noted that they were aware and not aware of their errors in the assessment, with the remarks that they were trying to alleviate them by re-examining themselves and increasing the degree of objectivity. Moreover, the obtained results also show that most respondents are satisfied with the existing assessment method. Teachers tend to regularly monitor, examine and evaluate students to become as fair, objective, and more satisfied with their way of teaching.
