The NITC represents the five main teaching unions – the NASUWT, INTO, UTU, NEU and NAHT.
In a statement its chairman, Justin McCamphill, said the deal was “a fair and necessary recognition of our members’ dedication and hard work during a period of significant financial pressure.”
“Our member unions conducted thorough consultations with their memberships, and the collective feedback has been clear,” he said.
“While the broader campaign for better funding and working conditions continues, this offer represents the best achievable outcome on pay for this year.”
The secretary of the NITC, Mark McTaggart, said the pay deal brought “welcome certainty for teachers”.
“Our focus now shifts to ensuring the minister delivers on the parallel and critical agenda of reducing teacher workload,” he said.
“The recommendations of the Independent Panel on Workload provide a clear blueprint for meaningful change, and we expect swift and tangible progress.”
