KEYES, Calif. – Administrators in the Keyes, California school district decided to give all K-2 students free breakfasts this year, served in the classroom.

The effort is part of a broader federal program inspired by first lady Michelle Obama that encourages schools with high proportions of low-income students to offer free food to everyone in the district. It’s called “community eligibility.”

But after a year of serving students breakfast in class, teachers at Keyes Elementary School are putting a stop to it for next school year, though the reasons why aren’t exactly clear, the Ceres Courier reports.

The local teachers union filed a grievance against the district regarding the program, and school officials announced Wednesday that it’s no more.

“Regrettably, the District will not be institution the Breakfast in the Classroom program for the 2015-16 school year at Keyes Elementary School,” superintendent Cynthia Schaefer told the news site.

“The district believes that it’s a good and beneficial program,” she said. “Students are fed and prepared for school versus empty hungry tummies an hour into class. If everybody came at 7:30 we couldn’t handle everyone in the cafeteria anyway; the cafeteria is not big enough.”

Union officials refused to discuss the problem with the news site.

Schaefer said roughly 80 percent of the district’s 1,275 students qualify for free meals, but only about 20 percent participated in the free breakfast program coming into the current school year, largely because parents didn’t drop their kids off early enough to take advantage of it. That figure rose to about 80 percent participation when students could munch in class.

Officials killed the program at Keyes after teachers are complained about the 15 to 20 minute loss in instructional time, she told the Ceres Courier.

“There are a number of issues to be worked out regarding the program, including employment issues that need to be negotiated with the teachers union,” she said. “The district will continue to serve breakfast for students each morning in the school cafeteria.”

Keyes teachers aren’t the only ones to raise issues with the federal breakfast in class program.

South Carolina parent Lakisha Barber recently told ABC 15 students should come to class prepared to learn.

“I just feel like as soon as they hit the classroom it should be about their studies and their academics and not necessarily about the food,” she said.

Another parent, Crystal Carter, also thinks it’s a bad idea.

“My kids, of course, have ADHD and ADD, they get distracted too easily, so to me, yeah, there’s a lot of distractions in the classroom as well, especially when you’re eating,” Carter said.

In Los Angeles, Lilian Ramos told the Associated Press she takes offense to the federal breakfast program’s implication that she neglects her children.

“They say if kids don’t eat they won’t learn,” she said. “The truth is that many of our kids come to school already having eaten. They come here to study.”

Ramos is among a group of parents at UCLA Community School who are warring with officials to end classroom breakfasts.

“We want then to serve it in the cafeteria,” mother of three Raquel Martinez told the AP. “That’s what the cafeteria is for.”

There are some people, however, who are simply determined to force schools into the government program regardless of objections from parents and teachers.

“State legislation in the form of AB 1240 authored by Assemblymen Rob Bonta, D-Oakland, and Tony Thurmond, D-Oakland, is seeking to take such issues out of local control by mandating that lower income districts be forced to participate in Breakfast in the Classroom,” the Ceres Courier reports.

“The year 2015 was a milestone in the nation because for the first time in history over half of students in public schools in the United States come from low-income families.”
