Now,however,with the development of the subject,and the reduction in the number of departments contributing to it,there are far fewer models to be found in schools. The majority of schools now teach units of work in each of the specialist areas,with some collaboration in planning and assessment to ensure coverage of the National Curriculum and coherence in pupils’ experiences. During Key Stage 3, pupils are exposed to a range of specialized areas,usually including food technology, resistant materials,systems and control and textiles technology and sometimes including graphics. Links between these different areas may be made by some specialist teachers who have knowledge of what pupils have covered in other units,but this is not always the case. In Key Stage 4,pupils select one specialist area of study which they follow to examination level.
