In the context of international systemic reforms promoting professional standards for teachers and inclusivity of diverse students in schools, this paper presents and demonstrates conceptual means by which educators can critically respond to the uncomfortable couplet of standardisation and difference. This is primarily achieved by theorising alternative ways of making sense of difference. Core to the argument is that standards can become more than prescriptions for educating in the same way when teachers recognise their positionality, examine the socio-cultural context of their work, and take action to ensure equality or equity of opportunity within the classroom. The paper is presented in three sections. The first section addresses the use of teaching standards in the United States and Australia, examining various ways inclusive education is articulated as a standard for practice. The second section engages theory from critical disability studies as a fillip to thinking differently about disability. The final section creates conceptual space for educators to move effectively between different intentions -- their own as practitioners, the profession's standards, and socio-material conditions involving ethics and accountability. On the whole, conveyed throughout the paper is the necessity for teachers to orientate towards contextual sense-making of professional standards to support inclusive practice.
