The staffing arrangements for all schools are published annually on my Department's website. At primary level, this is done via what is known as the Staffing Schedule and the relevant circular in relation to it for the 2014/15 school year is Circular 0007/2014. The Staffing Schedule currently operates on the basis of a general average of 1 classroom teacher for every 28 pupils.
At post-primary level, the staffing arrangements for the 2014/15 school year are also published on the Department's website although not in Circular format. Teachers at post-primary level are allocated using a PTR of 19:1 (18:25 to 1 in the case of DEIS schools and 23:1 in the case of fee-charging schools).
