Schools where serious structural problems were discovered late last year are being briefed by the Department of Education as to the kind of remediation works that will take place over the summer holidays to bring the schools up to standard.
The issues included internal and external wall faults.
Interim measures, such as scaffolding structures, were put in place at 22 schools last October and November to ensure that they were safe for pupils and staff.
Some schools were forced to close their upper storeys for a number of weeks and bus children to alternative accommodation.
A large section of one of the schools, Ardgillan Community College in Balbriggan in Dublin, was closed last October and has remained shut since.
In a statement the Department of Education said that "a specific remediation plan" is being put in place for the college. However, the department has declined to give details at this stage as to the nature of the work to be carried out at Ardgillan or at the other schools.
The faults found at the college were the most serious.
A number of schools, including Ardgillan, were briefed this week about the nature of the work to be carried out over the summer months. More schools will be briefed next week.
Initial investigations have taken place at the schools, allowing engineering experts to design permanent remediation works for affected schools.
Planned detailed structural assessments of 17 additional schools built by the same company, Western Building Systems, will also take place this summer.
In its statement the department said the minister would provide further details of the remediation programme when all of the 23 schools involved, including Ardgillan, and their patrons have been briefed.
