The measure could come up for a vote as early as today in the Florida House. The Senate is working on an identical bill.
The bills aim to tackle the beginning phases of a deep reduction in the number of students in Florida classrooms by 2010. Voters ordered the provision in November when they changed the constitution to impose caps on students assigned to each teacher.
The measure banks on some parents allowing their children to forgo their senior year if they take all the required courses before then. It reduces from 24 to 15-and-a-half the number of credits needed to graduate, letting those students who want to skip electives leave school early.
That part of the class size reduction plan drew some objections from Democrats who say it undermines the effort to adequately prepare students for life after high school.
