District Broadband Speed Report Information

You can view district-level speed test information using Measurement Lab's NDT Statistics by School District (WI) dashboard. This dashboard is a public report of broadband speed test information at the school district level, with filters available to further refine the data shown.

About the Data

Data in the NDT Statistics by School District dashboard comes from the Measurement Lab (M-Lab) broadband speed test, which collects and open, public data set of broadband speeds across the country. M-Lab's NDT speed test is designed to precisely and accurately measure the user experience of accessing files on the internet, and tests both connection speed and latency. For more information on this speed test and DPI's broadband speed testing campaign, refer to the Broadband Speed Test page.

Refer to Measurement Lab's Using M-Lab Data in Broadband Advocacy and Policy article for information and recommendations on using this data in analyses and reports. If you would like to use these charts or the data they present in your own reports, please contact with any general questions, particularly with respect to comparing NDT statistics to other datasets.

Using the Dashboard

Filtering Report Results

At the top of the dashboard, you can filter the results by date range, school district, and internet provider. To see results for just your school district, select the Only button next to your district in the School District filter list. If your district doesn't appear in the School District list, select a larger date range and check again.

Samples by District

In the Samples by District section, you can view the number of upload and download speed tests taken by users in each school district selected in your report filters. This section shows tests taken per day as well as the total number of download and upload tests in each district.

Overall Statistics

In the Overall Statistics section, you can view overall internet performance information for the districts selected in your report filters.

broadband overall statistics metric

The charts in the Overall Statistics section show both internet speed measured and latency to help you get a more complete picture of internet performance in a school district.

Internet speed is measured in megabits per second (Mbps) and describes the relative speed at which packets of information are sent and received over the internet. The FCC defines broadband internet as having a minimum of 25 Mbps download speed and 3 Mbps upload speed. Latency describes the time it takes for a request sent from a computer to reach a server and the server's response to be received, or the "round trip" time for data sent over the internet, and is measured in milliseconds. Latency greater than 100ms can often result in noticeably poorer internet performance, especially for video conferencing. 

Internet speed and latency are both important measures for overall internet performance. For example, being able to send and receive a high amount of data per second could be described as "high speed internet," but high latency can still make internet performance feel slow or interfere with video streaming.

Percentage of Tests by Service Levels

In the Percentage of Tests by Service Levels section, you can see the percentage of upload and download tests that fall within specific internet speed ranges. Under Performance, you can also view the number of tests taken per internet service provider.

Please note that the internet provider names in the By Provider metrics may not be familiar. The names shown there are the internal names used by the internet providers, rather than the internet providers' business names. To find out the name a provider uses to do business (the "doing business as" name), search for the provider name from the report using a search engine such as Google.
