Abstract
The recent influence of developmental theories of occupational choice upon guidance practice in Britain is criticised. It is suggested that people do not typically ‘choose’ occupations in any meaningful sense: they simply take what is available. Moreover, the career of the typical industrial worker cannot be meaningfully understood in terms of self-actualisation and implementing a self-concept: guidance work based upon these concepts is accordingly unrealistic. An adequate theory for understanding school-leavers' transition to employment in Britain needs to be based around the concept not of ‘occupational choice’, but of ‘opportunity structure’. Guidance should concentrate not on raising unrealistic expectations, but on helping people to adjust successfully within the opportunity structures open to them.
