Students from a Stoke-on-Trent college have gone to Downing Street to present a 20,000-name petition aimed at keeping their school open.
Staff and parents of pupils at St Josephs College have travelled down with them to also present their views.
The protest comes on the day consultation over the future of secondary schools in the city finishes.
The city council has said all schools will be reviewed independently after protests at plans to close all 17.
The protest came after the council considered replacing the 17 high schools with 12 "centres of excellence", including four academies.
