PERRY, Iowa – School district across the country are adding Wi-Fi access to school buses, for a variety of reasons.

In Iowa’s Greene County School District of Jefferson, officials installed Wi-Fi on two activity buses that usher students to off-campus sporting and other events. For away basketball games, for example, students leave school around 3:30 p.m., travel to play three games – freshman, junior varsity and varsity – and return to their school around 11 p.m., WHOTV reports.

“We have kids that are on the bus a lot going to events,” Greene County superintendent Tim Christensen said. “They get home late, and still have to do their homework.”

Adding the internet access helps students get a jump start on their homework, he said.

The Wi-Fi access is restricted by a password posted to a sign on the bus, as well as routers configured to block social media sites and streaming video. The district purchased a 30GB monthly plan with US Cellular for two buses, and could expand the effort if all goes well, Christensen told WHOTV.

“Being a rural district, we’ve got a lot of routes that are an hour long. So if it works we may expand to our route buses as well,” he said.

EducationDive reports that another Iowa district – Carroll Community School District – also recently installed routers on six activity busses for late games after parents complained.

The Huntsville City Schools in Alabama began installing Wi-Fi on its route buses in 2011, but for an entirely different reason.

Officials were looking to calm rowdy students on the district’s longer routes, which had a higher number of student conduct reports. In 2011, the average bus had 52 student conduct issues, but after officials fitted buses on the 20 longest routes with Wi-Fi that number dropped by 42 percent the next year. Officials added 12 more hot spots and number of conduct issues dropped another 17 percent during the 2013-14 school year, WAAYTV reports.

“As of the this year, those 32 buses saw 70 percent less student conduct reports compared to 2011 school year…,” according to the news site.

District spokesman Keith Ward said the internet on the buses is part of a broader effort to bring students into the digital age, which also includes computers for all students.

“We have overall seen decreases in disciplinary issues with the schools,” Ward told WAAYTV.

Huntsville schools was reportedly the only district in the nation with Wi-Fi enabled school buses when the routers were first installed in 2011.

Officials in California’s Coachella Valley Unified School District also installed Wi-Fi on buses last fall as a means of helping poor kids get online. The district gave all students a tablet computer last year, and fitted two buses with routes last fall, according to The Hechinger Report.

Those buses sit in trailer parks in the district’s poor neighborhoods to provide Wi-Fi access for students who otherwise would have none. The district has already faced one problem – the bus batteries last only about an hour – but are pressing forward with plans to expand the program.

The district’s chief technology officer, Michelle Murphy, is looking into solar panels as a means of charging the batteries, while finance officials are trying to find ways to come up with the roughly $290,000 to add access to all of the district’s 90 buses, according to the Report.
