About 90 students held the sit-in Friday morning at Shelton High School, where administrators have barred senior James Tate from the June 4 prom.
Most students returned to class when ordered. Some refused and were sent home for the day. They planned to rally later Friday to support Tate.
Tate and two friends last week posted 12-inch-tall cardboard letters reading, "Sonali Rodrigues, Will you go to the prom with me? HMU -Tate." HMU means hit me up, or call me.
Rodrigues said yes. But Tate was suspended when administrators deemed the stunt a safety risk and violation of school policies.
There has been an outpouring of support on Twitter and Facebook. Many companies have offered freebies to help make this prom happen free of charge for the students.
Tate appeared on "Jimmy Kimmel Live" Wednesday night.
