General secretary Daniel Kebede said the union's members "should be proud of what they have achieved through a hard-fought campaign". However, he warned a "major pay correction" was still needed.
The largest education union in the UK has voted to accept the government's 5.5% pay rise for teachers in England.
In a snap poll, 95% of National Education Union (NEU) members who responded accepted the 2024/25 offer.
Around 300,000 state school teachers were asked to vote. The turnout was 41%.
Schools will receive GBP1.2bn of additional funding in the 2024/25 financial year to help cover the costs as part of the deal, according to the NEU.
"Our members should be proud of what they have achieved through a hard-fought campaign," the union's general secretary Daniel Kebede said.
However, he also warned: "The government should be in no doubt that we see it as just a first step in the major pay correction needed.
"Teacher pay in England was cut by around a quarter in real terms under the Conservatives and is significantly lower than it is in Scotland. This is unsustainable.
"Without a major pay correction to restore the competitiveness of teacher pay, the desire to tackle the recruitment and retention crisis promised by today's government remit letter to the School Teachers' Review Body will come up short."
