Scotland's largest teaching union has rejected the latest pay offer from the Scottish government and councils.
EIS general secretary Andrea Bradley called the proposal "another inadequate offer to Scotland's teachers".
The latest offer includes a 6% pay rise in the current year and a further 5.5% in the new financial year.
Officials from the NASUWT said while the deal was "substantially adrift from a real terms pay award" they would consider it.
Both unions have scheduled strike dates and they will remain in place.
