LISBON — School officials and others informally agreed Thursday night that to remedy problems with the high school building, they should seek outside opinions on the best course of action.

A committee of school officials, parents and council members will seek a request for qualification, the start of a process that will bring in architects and engineers to look over the high school.

That step is in reaction to last week’s announcement that the school was placed on probation by the New England Association of Schools and Colleges for failing to adhere to standards for accreditation.

The problem is not programs or staff at the school; it is the building itself, which is considered in need of major renovations. Whether to revamp the existing building or seek space elsewhere is something that will be addressed in the future.

“We can’t do anything, really, until we know what the condition of the building is,” said Prudence Grant, chairwoman of the Lisbon School Committee.

She said an independent group of engineers, architects and others should be able to advise school officials on the best and most affordable way to tackle their problems.

The process could take three or four months, Grant said.
