High school students who want to graduate in three years instead of four would need a 3.0 grade point average under a bill the House unanimously passed.
The vote sent the legislation back to the Senate for consideration on the session's final day.
Under a 2003 law, students can opt for an 18-credit three-year high school diploma and remain eligible for the accelerated graduation by keeping only a 2.0 GPA.
Tenth-graders would also have to earn a three, or grade-level, score on the Florida Comprehensive Assessment Test. That requirement that would eliminate about 60-percent of students. And six of the 18 credits would have to be in advanced classes.
