The BBC is reporting that the EIS and other unions argue the rise is needed to restore the value of salaries but the Scottish government and councils are offering most teachers a 3% rise.
The motion could lead to pay strikes for the first time in decades. General secretary Larry Flanagan is also expected to address the pay campaign in his speech.
The EIS has been running a campaign calling for a 10% rise for several months.
Speaking to BBC Scotland, Mr Flanagan said: “Today’s debate will demonstrate that pay is the single biggest issue for teachers at the present time.”
“If a negotiated settlement fell well short of 10%, members will be balloted on the offer and ultimately on industrial action if that is the only route forward.”
The EIS would be likely to hold an “informal” ballot first to seek the views of its members before holding a formal ballot which could provide the legal backing for action.
The 10% pay claim was submitted by the four unions representing Scottish teachers – the EIS, the SSTA, the NASUWT, and Voice the Union.
