The Collaborative University-School Partnership project (CUSP) documents the experiences of a New Zealand university and seven schools as they collaborated on the development and introduction of a reframed practicum programme in the first year of a three-year undergraduate primary initial teacher education (ITE) programme. The CUSP programme was designed to enhance teacher, university lecturer, and student-teacher experience of the school-based components of the ITE programme by weaving the university and school-based components into a more coherent and seamless whole to which each community contributed and benefited. In the co-constructed and reconceptualised school-based programme, lecturers and teachers became jointly responsible for student-teacher development.
