Minister for Education Joe McHugh has said the initial assessments of all the 42 schools at the centre of concerns over structural deficiencies will be completed by close of business tomorrow evening.
Mr McHugh - who was briefed on the process by officials at the Department’s office in Tullamore, Co Offaly - said the results will be analysed and released over the coming days.
An update is due this evening with the outcome of the latest round of inspections.
So far, engineers have carried out safety checks on half of the schools, with four requiring remedial work that will result in some sections of the buildings being closed for a time.
Efforts are under way to source temporary offsite accommodation for a number of classes at Tyrrelstown Educate Together National School, St Luke's National School, also in Tyrrelstown, and Gaelscoil Eiscir Riada in Lucan.
Arrangements have already been put in place to accommodate students at Ardgillan Community College in Balbriggan, where issues were first detected, resulting in the closure of part of the school.
Two other schools, Castlemills Education Centre in Balbriggan and Tallaght's Scoil Chaitlín Maude, will require some external remedial work, which will be completed during the Halloween break.
Six schools - Luttrellstown Community College, Gaelscoil Shliabh Rua in Sandyford, Broombridge Educate Together National School, Scoil Choilm in Porterstown, Gaelscoil Thulach na nÓg in Dunboyne and Gaelscoil Teach Giúise in Firhouse - require no intervention and classes will continue as normal after mid-term.
The schools were built by Western Building Systems.
In a statement, the Co Tyrone-based company said it is "engaging constructively with the Department and remain available to meet with the Minister for Education."
The company added that it is "committed to better understanding why schools previously certified as substantially complete and suitable for occupation and which also had defects certificates subsequently issued by the Department's advisors are now being assessed by the Department."
