Each year the Department for Education produces the Teacher Supply Model, an estimate of the number of trainee teachers required to meet the needs of the school sector in England. The last estimate produced was for the 2015/16 academic year.
The department has published the Teacher Supply Model for 2015/16 in full. This identifies the inputs and assumptions applied to produce our estimate, including central projections of the overall number of teacher entrants needed up to the 2019/20 academic year and beyond. This information is published online at: www.gov.uk/government/publications/teacher-supply-model
