Technology is pouring into schools faster than their Wi-Fi can keep up with it. Virtually all school officials in a recent survey of 447 school districts said they will need to upgrade their Internet speeds within three years.

The survey was done by the Consortium for School Networking (CoSN), a professional association for district technology leaders. Education Super-Highway, which promotes high-speed Internet in schools, recommends a download speed of 100 mbps (megabytes-per-second), for a school with 1,000 students and staff. But, the organization says "the typical public school has the same Internet access as the typical home -- but with 100x more users."

The solution? Mostly more money. Nearly three-quarters of districts in the CoSN survey said the cost of the monthly Internet charges are a barrier to getting the speed they need.

That wasn’t the only problem. Just over 10 percent said their Internet provider was not able to give them the higher speed they required.

The map shows Department of Education data on the maximum possible download speeds available at more than 70,000 schools in the country. It does not show whether the school has the top speed. You can see schools in your town, or nearby, by entering your zip code into the box above the map. By clicking on the markers you can see more specific information on download speed.
