Members of Scotland's biggest teaching union have rejected a 5% pay offer and backed strike action.
The EIS union said 78% of its members took part in a consultative ballot over pay and conditions.
A total of 94% of those taking part voted to reject the 5% pay offer put forward by local authority body Cosla and 91% supported strike action in pursuit of a better pay offer.
A statutory strike ballot of EIS members will now take place.
If teachers back strike action in this statutory ballot then the EIS will move to take industrial action at schools across Scotland.
