MADISON, Wis. -- Classes began on Tuesday and students at all levels of education could feel the effects of budget impasse at the state Capitol.

Primary and secondary education could see a difference in the number of students per class, and low-income students at University of Wisconsin campuses are already feeling an impact.

The Madison Metropolitan School District said that not having a state budget isn't a problem for now.

"This school year, we've already got a contract set, classroom size set," said Joe Quick, a communications specialist for the Madison Metropolitan School District.

But the budget could bring bigger cuts next year.

"There will still be cuts next school year just because of the revenue limit law, but depending on how this state budget works, it could be even deeper cuts than what we anticipate," Quick said.

Quick said 85 percent of a school district’s budget comes from personnel, meaning that teachers would likely get cut first.

"You'd have to be looking at large class size," Quick said.

Some area parents said they were frustrated about the budget stalemate.

"I want (lawmakers) to stand up, start working together, forget the pointing across party lines and make some changes, because it's affecting all of our kids," said Lisa Smith, mother of a Madison third-grader.

The K-12 system isn't alone in the educational limbo.

The University of Wisconsin's ability to award the Wisconsin Higher Education Grant, or WHEG, is at a stand still because the budget is not finalized.

"When the state budget passes, if the funds are sufficient for higher education to open the door, we will begin awarding again," said Susan Fischer, UW financial services director.

At UW-Madison, 150 students received aid -- but they might have to pay it back.

"It's frustrating. We'd like to see our students, especially our low-income students, not be nervous about going for a higher education," Fischer said.

Mario Selph, of Delavan, said he'll probably have to drop out of the University of Wisconsin-Whitewater this semester. He said he can't afford tuition without state help.

UW-Stout senior Rose Reisinger said she'll have to take out more student loans if her aid doesn't come through. She said she's frustrated lawmakers can't agree on a budget.

The majority of UW students receiving the Wisconsin Higher Education Grant are not affected, WISC-TV reported. The 150 students who might have to pay back their grants are those who applied and were accepted after June 26.

Lawmakers are more than two months late in passing a budget because of disagreements between the Democratic-controlled Senate and Republican-led Assembly.
