This qualitative study investigated the perspectives of Western Australian teachers at the Proficient career stage on the Australian Professional Standards for Teachers (APST), or 'the Standards'. Fifteen teachers from five independent schools participated in semi-structured interviews and five themes were identified, under the broad categories of Strengths and Challenges of the Standards. Strengths identified were that the Standards support professional practice and career development and are user-friendly. Challenges identified were that the Standards can present challenges to professional practice and are problematic in the way that they are presented. Importantly, participants felt that the Standards ignored important social and relational teacher qualities.
