In 1999,Tulsa's own Remington Elementary school took a hit from the destructive May tornadoes.
Now a state senator wants to give schools a chance to shut down early for the summer.
Right now, Tulsa school children do three tornado drills a year.
Changing the calendar would also mean changes for mandated testing and vacations. And some are concerned it could even put more children at risk by starting school the first of August in the heat of summer.
"I worry more about extreme heat and lightening, than I do about tornadoes it kills more people it's more dangerous it happens more often," said Bob Roberts who oversees Emergency Management for Tulsa Public Schools.
Roberts says the drills are more effective along with identifying the safest places in schools.
