The Education (Review of Staffing Structure) (England) Regulations 2005 place a duty on relevant bodies (school governing bodies for schools with delegated budgets and LAs for schools without delegated budgets and Pupil Referral Units (PRUs)) to review every maintained school’s and PRU’s staffing structure and prepare, by 31 December 2005, a plan for the full implementation of any changes arising from the review by 31 December 2008. In this context, a maintained school means a community, foundation or voluntary school; a community or foundation special school; and a maintained nursery school. The reviews must be conducted with a view to ensuring that the management and deployment of all staff and the allocation of responsibilities and duties is effective and focused on teaching and learning to raise standards. All staff and representatives of recognised trade unions must be consulted during the review. Head teachers are under a duty to advise and assist the governing body in conducting the review and preparing the implementation plan.
