Headteachers have "overwhelmingly" rejected the government's pay offer, with a union representing school leaders branding it "inadequate in every respect".
The Association of School and College Leaders (ASCL) has not ruled out asking its members to vote on formal strike action after hitting out at the government's "lacklustre set of proposals" for ending the industrial dispute.
Members of the school leaders union followed the National Education Union (NEU) in knocking back the government's offer on Tuesday.
The NEU had previously branded the government's offer of a £1,000 one-off payment granted in 2022/23, as well as a 4.5% average pay increase for the following year, as "insulting".
Some 87% of ASCL union members who took part in a survey voted to turn down the deal, with 69% citing the "inadequacy" of the additional funding for next year as the main reason for rejecting the offer.
