Numerous studies have dealt with the importance of assessment for learning (AfL) in higher education, arguing that AfL helps to promote students' learning and supports them in becoming self-directed learners. The majority of the recent literature focuses mainly on the role of individual aspects of AfL. Less attention has been paid to the interrelation of different aspects of AfL. The current study argues that AfL combines authentic assessment tasks given to students, feedback from teacher educators, peer assessment and self-assessment. The aim of the current study is to understand student teachers' experiences of AfL practices in higher education, focusing on the reasons why student teachers do not always find the practices supportive. The study conducted semi-structured interviews with 20 student teachers and analysed them using an inductive content analysis method. The findings indicate that student teachers have had some experiences with individual aspects of AfL. A critical finding is that, when teacher educators continually dominate in the assessment process, summative assessment remains the principal way of assessing student teachers, thus hindering the supportive role of other AfL practices. The current study also finds that learning in higher education is still quite grade-centred, which affects student teachers' learning.
