Myton School held a non-uniform day on March 11, which was also a fundraising event.
Children were encouraged to dress in the colours of the Ukrainian flag for a minimum donation of £1.
Blue and yellow wristbands were sold by sixth formers and there was also a cake sale.
The Myton School flag was replaced by the Ukrainian flag and the school plan to fly this every Friday until further notice.
The school managed to raise £3,800 with their efforts.
Headteacher Andy Perry said “We are really proud of our students who expressed a wish to donate funds to the Ukrainian people within days of the crisis.
"We would also like to thank parents and carers for their incredible support for this cause.
"All proceeds will go to the Disasters Emergency Appeal and it’s great to know that our donation will be doubled as the government will be matching the amount raised.”
