The core function of the redeployment arrangements is to facilitate the redeployment of all surplus permanent teachers to other schools that have vacancies. The redeployment of all surplus permanent teachers is key to the Department's ability to manage within its payroll budget and ceiling on teacher numbers. Thereafter, schools are required under the panel arrangements to fill permanent vacancies from supplementary panels comprised of eligible fixed-term (temporary/substitute) and part-time teachers. The teacher referred to by the Deputy is a permanent teacher who is currently not surplus to the school in which she is employed. She does not therefore come within the redeployment arrangements.
