Feeling respected is important to students. Classroom respect, crucial for creating effective teacher−student relationships, is essential for maximising achievement. This article discusses findings from our study into the teacher behaviours that Year 12 and 13 mathematics students and teachers consider respectful. Dispositional, pedagogical and professional behaviours were identified as being important. Showing respect includes listening to students, being well prepared and on time, holding high academic expectations, and treating students’ errors constructively. For students to feel respected, teachers need to know their students well, prioritise one-to-one interactions, sensitively guide next learning steps, and avoid portraying disrespect.
