The tertiary education of Teacher Education Students (TES) plays a vital role in preparing highly qualified educators, especially in terms of mathematics education. However, best practice in how to develop TES during their studies has been very under researched (Norton & Allen, 2020), with some research addressing only the secondary perspective (Hine & Thai, 2019). This short communication will report on the findings of a doctoral study, investigating TES’ self-perception and readiness to teach primary mathematics. Interviews were conducted to evaluate TES’ readiness, focusing on three key areas: mathematical content knowledge, mathematical pedagogical knowledge, and mathematical knowledge for teaching. The findings from this research identified areas where TES require further training and offer strategies on how these can be achieved during TES’ tertiary education.
