Mr. Pat Burke:

Yes. Following the Comptroller and Auditor General's report and as part of the Croke Park agreement in its initial negotiation, we extended, from two to three, the allowable number of periods per week during which teachers could be called upon. The effect means it is significantly more likely that the 37 hours will be called on in full. School budgets for alternative substitution have also been restricted. We are more optimistic about it now.
