It is necessary to determine the cognition of individuals to understand and interpret their behavior. It is claimed that a certain number of structures can be reached by evaluating the events that emerged as a result of people's experiences with the repertory grid technique. These structures can be good or positive, as well as bad or negative, in a bipolar way. While the phenomena (humans, views, objects, events) are called "matter", the concepts associated with the events are called "constructs". Constructs could be nouns or adjectives, or a concept that includes two or three terms. Cognitive constructs that are reflected in the repertory grid form are employed to understand the conceptual framework of the individuals about a certain field, subject or object, and the way they assess events and their decision-making processes associated with the subject. The present study aimed to investigate the cognitive constructs of native language educators about the ideal exam practices. Since the study had both qualitative and quantitative dimensions, it was conducted with the exploratory sequential design, a mixed research method. The study was conducted with 24 native language teachers at different educational levels (preschool, primary school, junior high school, high school) during the 2021-2022 academic year. In the study, the repertory grid technique was employed since the study aimed to determine the cognitive constructs of native language educators about the ideal exam practitioners. Cognitive constructs included in the forms completed by the native language educators were transferred to the computer environment and analyzed with thematic analysis. The study findings revealed eight main constructs including ethical principles, employment of various measurement and evaluation methods and techniques, employment of valid tools, reliable tools, competent development and application, communication and counseling skills, consideration of the measurement and evaluation as a feedback, and measurement planning, and a total of 240 cognitive constructs.
