As much as it is crucial to monitor the Turkish Teaching Program which was revised according to constructivist educational approach starting with 2005-2006 academic year, it is equally important to adopt and implement assessment and evaluation approaches based on this new approach. Assessment and evaluation practises in the constructivist educational approach are based on process rather than product. Therefore, it is imperative to assess student interests, attitudes and skills from all relevant aspects. Hence, assessment tools that students can employ to review themselves, their peers and their work to improve themselves should be used in assessment and evaluation phase instead of the traditional assessment tools that focus on the product such as written and oral exams, multiple choice and true-false tests. This study aimed to investigate the assessment and evaluation methods used by teachers in classrooms where the Turkish Teaching Program prepared according to constructivist educational approach was utilized. With this aim in mind, data were collected from in-class assessment and evaluation practises of 41 teachers of Turkish by using the checklist and semi-structured interview form developed by the researchers. Descriptive statistics and content analysis were employed to analyze research data. Research results present that teachers mostly preferred open ended questions while assessing writing skills; they used oral exams to test speaking and listening skills and they showed less than expected interest for supplementary methods during the assessment and evaluation phases.
