The Common Application System (CAS) is the system that manages the application of students to the seventeen participating schools in the Limerick area. This system is carried out in conjunction with the Limerick Education Support Centre (LESC). The aim of CAS is to “assist and support the parents/guardians of children seeking a place in 1st Year in one of the 17 CAS post - primary schools in Limerick City and environs.”
