It's a protocol UTC students know all too well.
"It normally happens when I'm in my 8am class and I have to leave the building and then I have to walk all the way to some area they tell us to go to stay away," said Katie Disalvo.
UTC Spokesman Chuck Cantrell says the affects of these bogus bomb threats is widespread.
Campus and city police, firefighters and the bombsquad all have to respond.
"It's very costly to taxpayers in terms of loss productivity, by all these responders, it's very important to students who lose time in class and faculty members who lose class time with the students," said Cantrell.
Many speculate the threats are made to get classes cancelled. Especially during exam time.
The calls are difficult to track, so the crime usually goes unpunished.
The one's that suffer are the ones prepared to take their finals.
"I wanna get it out of the way when the information is fresh on my mind. I don't want to wait until after break when I might of forgotten most of the information," said Michael Goss.
Students say they're frustrated and want the University to take more action.
" It seems as though they're going under the bridge with this, but if they tackle this more seriously, I think they'd be a lot more people that are going to be very mad if they learn about someone doing these bomb threats."
But Cantrell says the key to stopping it lies with the students.
"Someone out there knows who did this and they need to come forward and share that information with law authorities," he said.
To others, the solution is simple.
"Just study and take your test and don't disrupt people," said Disalvo.
