Twenty eight Northern Ireland schools are to benefit from a £800million renovation fund, the education minister has announced.
Ms McIlveen announced the spending drive under the major capital works programme.
The schools which are attended by more than 25,000 pupils combined will benefit from an estimated capital investment of £794m.
A 'major work' is a capital project that costs in excess of £500,000.
That could be a new school building, renovation of an old building, extensions or construction of a new school building to allow for an amalgamation of two or more existing schools.
"I should stress," the education minister told the Assembly on Monday, "authorisation to proceed to construction on any individual project will be based on the level of capital funding available at the point when a design is complete and all necessary approvals have been secured."
She said the projects could be a number of years out and would not be completed until the end of this decade at the earliest.
She denied a claim of "electioneering" in the run up to the May Assembly poll.
In response to UTV's enquiries about the breakdown of the Major Capital Works programme for individual schools, a spokesperson for the Department of Education said: “It is important to note that these figures are broad initial estimates at today’s prices of potential construction costs only, and they do not include inflation, site costs, professional fees or VAT."
“In addition," it continued, "authorisation to proceed to construction on any individual project will be based on the level of capital funding available at the point when a design is complete and all necessary approvals have been secured.”
