The authorities of second level schools may appoint substitutes for teachers who are absent for any of the following reasons: jury service, paid maternity leave, certified sick leave, paid study leave, short-term secondment, incareer training, in certain circumstances, or examining at the oral/practical elements of the certificate examinations. I am satisfied that in general the system of substitution is working satisfactorily. Details of the number of second level teachers who were absent during the summer term and the number of days involved are not readily available in the absence of a detailed analysis of significant numbers of substitution claims.
