This paper presents the findings of a longitudinal study on the effectiveness of an innovative one-year pre-service Graduate Diploma of Teaching (secondary) for teachers of Technology. The timing of this study is significant. Over a decade of review and adjustment to the Technology curriculum, leading to the new learning area of Technology in the New Zealand curriculum, Ministry of Education (2007), has caused many teachers in New Zealand schools to retrench to an earlier approach or make their own interpretation of curricular requirements. This situation in schools created the need for those involved with pre-service teacher education to prepare programmes that signpost pitfalls while building on students' own strengths and those of the curriculum to cope with the wide variety of interpretation and pedagogical approach of school communities. This paper suggests a way forward.
