Osceola County School officials are changing the schedule at Osceola High School a month before the start of school.
"My daughter is a very bright student and has had her career planned out since ninth grade," Cheri Stickney told Local 6. "This puts a complete wrench in her plans."
Osceola High School is the only school in the district that has been on what's called the 4x4 block, which means students take four classes each semester.
Now they will move to a seven-period schedule, where they will study six subjects year-round.
In an email to Stickney, the assistant superintendent said because the district was notified late about changes to state graduation requirements they couldn't make the change sooner.
"Once we had considered all concerns, we came to the conclusion that it was best for the students to make the change this summer," Dr. Michael Akes said.
Many parents and students showed up at a school board meeting Tuesday evening to discuss the issue
The change will go into effect when school resumes in August.
