Mr. Seán Ó Foghlú:

It would depend on what the arrangement was. We have a supervision and substitution scheme in place in schools. If substitution takes place under the supervision and substitution scheme, it is done by existing teachers. If there is an arrangement under another category of leave that the school cannot fill, it will bring in, if possible, a teacher in the subject, but if that is not possible it will bring in somebody to supervise the class.
