It has been factored in to the evidence base that we have based the pilot project on. We do know the importance of supply teaching in raising standards in Welsh schools and the ability to maintain a level of consistency with one supply teacher working across a group of schools so that teacher gets to know those schools and those pupils better. Conversely, the pupils beginning to develop a relationship with one particular person is one of the benefits, I believe, of the pilot that we're currently investigating. Clearly, these aspects will form part of the evaluation of the pilot and hopefully will give us the information as to whether this pilot should be extended to cover the entirety of Wales and whether it should go beyond, as it currently does now, using newly qualified teachers as the supply teachers in that particular pilot, and whether that should apply to the entirety of the supply teaching workforce.
