The plan - still a work in progress - would be for students to walk out of class at 10 a.m. that Friday but stay on campus to peacefully protest gun violence.
"We certainly agree on the need to address gun violence and school safety", Hess said, speaking on behalf of himself and Brian Stefanich, the high school's principal.
"I remained at the school for the remainder of the day to provide support and/or guidance", she said.
"Please be advised that the Needville ISD will not allow a student demonstration during school hours for any type of protest or awareness!"
But their invite to other students to join them in protests and walk-outs has resulted in a school district in Houston issuing a clear message to its students that disruptive protests would not be tolerated.
"I wish that this doesn't stop because we just can't let the 17 people that died, let their names go in vain and then just forget about it and wait till the next shooting happens", Lobos said.
Spokane Public School leaders said they are still discussing how they will respond to this national call to action.
"We reached out to 50 or 60 students", Gessen said Wednesday. "They're not walking out for the entire school day", observed one commenter.
A 16-year-old student named Alfonso Calderon who was one of the survivors said: "Trust me, I understand".
"I told (students) dismissal today will look different".
Garcia said she envisions protest that includes chants - the National School Walkout logo includes the words "We are victims, we are students, we are change" - and speakers from the community and school clubs.
Hundreds of students from at least five Minneapolis schools took to the streets around noontime, marched for five miles along Nicollet Avenue and demonstrated before Minneapolis City Hall.
"We want our voices to be heard because, in the eyes of the government, our voices aren't heard".
