The importance of assessment is recognized in research and it is argued that assessment, teaching and learning are strongly linked with one another. If teachers want to have good teaching, for teachers it is necessary to care for assessment to make students with learning achievements. Assessment is starting by teachers and students from the beginning of schools, because of the importance that it has in teaching and learning. Teachers, administrators and students use different kinds of assessment to achieve the goals of learning and to get knowledge about the effectiveness of their teaching. Formative assessment is used for learning in the learning process, whereas summative assessment is using for grading and judging on students’ progress at the end of learning process. For this study two kinds of questionnaires were used. One was for teachers and one was for students. Every questionnaire had 31 questions. The questionnaires asked students and teachers about the use of the two types of assessment (formative and summative) in TTCs, advantages and disadvantages of assessment use and how teachers with varied background use formative and summative assessment. 150 respondents filled in the questionnaires. The results highlight the need for greater emphasis of assessment in the teaching and learning, moreover on the role and effectiveness of the concept of assessment in teaching.
