The current reforms of initial teacher education in the learning and skills sector in England are standards based and emphasize subject specialism. A qualitative study found that trainees generated knowledge resources through participation in their workplace, initial teacher education course and other social contexts, and from embedded and encoded workplace knowledge. It is argued that using a knowledge resources perspective, which recognizes how trainees generate knowledge and seeks to bridge gaps in their access to knowledge resources, would be more effective in supporting trainees' development than the recent reforms.
