To obtain a GTP place, a candidate must usually secure a training placement themselves at a school willing to support them as an unqualified teacher. However, some institutions organise this for them. The school will then offer to employ the student as a supernumerary teacher (i.e. not being used as substitute for employing a qualified teacher). With the school's backing, a formal application must then be made to a Designated Recommending Body (DRB). These are normally universities, colleges, local authorities or private educational companies. The DRB administers the application process, making the formal selection of successful candidates, and the payment of the TDA grant to the school, and provides tutor support for the student. Numbers are limited by the money made available by the TDA.
