Kent teachers will join colleagues across the UK on the picket lines next month after NUT members voted to strike.
National Union of Teachers (NUT) members in England voted in favour of strike action over pay and working conditions.
In the NUT's ballot, 91.7% voted in favour of strike action.
The NUT is calling the first day of strike action on July 5.
The union says the strike demands are to increase funding to schools and education, guarantee terms and conditions in all types of schools, and to resume negotiations on teacher contracts to allow workload to be addressed.
Kevin Courtney, acting general secretary of the NUT, said: "The NUT is not taking action lightly.
"In light of the huge funding cuts to schools, worsening terms and conditions, and unmanageable and exhausting workloads, teachers cannot be expected to go on without significant change.
"The effects on children's education are also real and damaging.
"As a result of school funding cuts, class sizes in primary and secondary schools are increasing, subject choices are being cut, and children are getting less individual attention as teachers and support staff are made redundant or not replaced when they leave.
"There is worse to come, with the Institute of Fiscal Studies predicting that the biggest real terms cuts to per pupil funding in a generation are on the way.
"There is already a teacher recruitment and retention crisis in our schools.
"Without significant change to the pay and working condition of teachers, this will simply deepen. We know that many parents share our concerns."
