This paper discusses the basic procedures, methods and techniques of evaluation in Science and Social studies classes. The key concepts related to evaluation are explained, and its possibilities and approaches are pointed out. The development of evaluation in teaching throughout history is also briefly described, and the authentic/alternative ways of evaluation that can be used in Science and Social studies classes are listed. Moreover, in this paper, evaluation is also examined from the perspective of the documents important for education. Based on them, the elements and evaluation criteria in Science and Social studies classes are determined. The paper also deals with the analysis of teachers' competencies needed for motivating, correct and adequate evaluation. The results of previous research conducted in this area are also presented.The second part of the paper presents the results of the research that aimed to examine the knowledge, attitudes and skills of future teachers for evaluation in Science and Social studies classes. The research was conducted among fourth and fifth year students of the Faculty of Teacher Education in Zagreb, with a total of 123 students participating in the research. For the purposes of the research, a special questionnaire was constructed consisting of 5 parts. They examined the knowledge and attitudes of students-future teachers about evaluation, and self-assessment of their abilities of evaluation in Science and Social studies classes. Based on the results obtained in the field of testing the knowledge and attitudes of future teachers, it can be seen that they are mostly indecisive in assessing the statements, which means that they are unsure of their knowledge and that their attitudes are vague. On the other hand, they assessed their abilities to evaluate in Science and Social studies classes to be well developed. What is more, suggestions for improvement in the field of evaluation in Science and Social studies classes have been identified, as for teaching future teachers for evaluation during their formal education.
