The employment of expatriate teachers is explored here through the perspective of their organisational commitment. Drawing on the results of a public school teacher survey conducted in the Emirate of Abu Dhabi in 2014, this study used a multilevel framework to investigate the effects of teacher characteristics, school environment, and district level human resource management policies and practices on expatriate teachers' school commitment. The results of the three-level model revealed that while teacher level attributes remained strong predictors of their school commitment, the social and organisational environment of the school greatly contributed to the organisational commitment of expatriate teachers. Interpersonal support within the school community and supportive work climates were crucial for expatriate teachers to build and sustain their commitment. Nationality was found to moderate the relationships between several workplace factors and teacher school commitment.
