A literature-based survey gathered 331 final-year preservice teachers' perceptions of their mentoring in primary science education from nine Australian universities. Data were analysed within five factors proposed for mentoring (i.e., Personal Attributes, System Requirements, Pedagogical Knowledge, Modelling, and Feedback). Results indicated that the majority of mentors (primary teachers) did not provide specific mentoring in primary science, particularly in the science teaching practices associated with the factors System Requirements, Pedagogical Knowledge, and Modelling. This study argues that mentors may require further education to learn how to mentor specifically in primary science, and proposes a specific mentoring intervention as a way forward for developing the mentor's mentoring and teaching of primary science.
