Vocational qualifications in England are undergoing another round of reform. This paper starts by reviewing the alleged weaknesses of English vocational qualifications, but argues that these do not necessarily establish a case for radical reform. The issue is not so much whether the system needs to be changed as the nature of the change that is needed. The paper argues for a more deliberative and incremental approach and proposes five principles upon which this should be based. These are the following: that the process of change is as important as the content of change; that institutions matter; that the purposes of reform need to be clear, consistent and realistic; that reforms should help to create a more unified qualifications system; and that the interests of the UK's other home countries should be considered.
