Sessional teachers in universities are often marginalised by their part-time status, availability for training, and invisibility within the institution's infrastructure. Nevertheless, tutors as a subset of this group, regularly have access to some training and development. This paper presents a methodological approach for implementing the BLASST framework for sessional staff at a New Zealand university, based on a project to benchmark support for tutors. Using Activity Theory, I discuss tensions associated with developing a training programme for tutors and how such an approach can aid the development of similar models for all sessional teachers.
