What is a ‘shortage subject’?
“Shortage subject” is a widely-used descriptive term rather than a single fixed statutory list. The working definition is: the subjects the DfE targets with the highest bursaries and scholarships and where recruitment most often falls short of the trainee need.
The evidence for a shortage is not just recruitment. A subject can meet its trainee target yet still rely heavily on non-specialist teachers (physics is the classic example), or show pressure through vacancies. The Teacher Workforce Explorer shows recruitment, specialist teaching and vacancies side by side so you can weigh them together.
