The engagement of both school and university has played a significant role in initial teacher education. The focus of this paper is the growth of an alternative style of school-university partnership from a single school to a Hub of 19 school-university partnership, in the inner-west suburbs of Sydney, Australia. Four school and university mentors who have participated over a seven-year period have completed surveys on their engagement. Using a Community of Practice (CoP) theoretical framework to underpin model development, it is possible to showcase the growth of the partnerships as important in informing discussion relating to the implementation of integrated school-university partnerships and practice.
