Overcrowded classrooms are a common thing for school's in California, but if Gov. Jerry Brown get's his way, we may see classrooms shrink a bit.

The governor's new school-funding plan looks to reduce the number of students in kindergarten through third grade.

In the mandate, schools must reduce class sizes or face a 10 percent funding reduction. But according to the chief business officer for the Sacramento School Distict, Ken Forrest, the school district can't afford it.

Forrest says the district stands to lose $7.1 million for in-state pupil funding because of declining school enrollment for next year. 

The state's new school funding program sets the goal of 24 students per class and districts must reduce their class-size gap by 28 percent by next year.

However, school districts can keep the larger class sizes if the teacher union agrees to it.
