This study investigates the sources of anticipatory socialisation of prospective primary headteachers in deciding to accept the school head post. In exploring their socialisation sources, a series of interviews with seven novice Malaysian primary headteachers was conducted. The transcripts from the semi-structured interviews formed the basis of the findings. The findings reveal that former headteachers substantially influence prospective heads' decision in accepting the decision to become primary headteachers followed by teachers' colleagues. Similarly, family members and heads' own willingness and ambition to become a school head also played crucial role in accepting the post as school heads. The results are important since little studies were found examining the concept of anticipatory socialisation within the context of socialisation sources in headship within Malaysian educational system.
