Teachers in Islamic schools are often required to navigate complex identities. They balance personal and/or school-based religious obligations with contemporary secular-based commitments to meet organisational demands for institutional compliance. Behaviourally, the motivations and attitudes of teachers play a vital role in shaping a learning environment that fosters a sense of community and caters to the needs of students. However, recent studies on Islamic education suggest a real struggle in managing such complexities. Consequently, scholars have called for specialized programs to counter such issues, focusing on the need for schools to renew their commitment to promoting educational values, principles and practices that are rooted in the Islamic tradition. Several higher education institutions have responded to this call by establishing programs in Islamic studies and Islamic education. Nevertheless, there is limited knowledge of the organisational and behavioural significance of such programs on the professional identity of teachers. Using semi-structured interviews, this article presents findings from four teachers who had completed a postgraduate qualification in Islamic education at an Australian university. The six-phase thematic data analysis, informed by Muslim identity and an Islamic worldview, revealed that secular teacher education provided participants with ‘a license to teach’ but lacked in ‘nurturing a purpose for teaching’. The findings also revealed a distinct connection between Islamic teacher education, professional learning and professional identity, whereby Islamic-based pedagogies ‘enlightened and empowered’ teachers toward becoming ‘faith-centred’ in their professional practice. While the study was limited to four teachers, it contributes knowledge to the Islamic education, organizational and behavioural fields of inquiry in two ways, by underlining that (i) the professional identities of Muslim teachers are shaped by a knowledge-seeking mindset, and (ii) Islamic teacher education and professional learning create pathways towards the renewal of teachers’ professional identities in Islamic schools.
