Education in the 21st century increasingly relies on strong, reliable access to the internet at school and at home. However, millions of students throughout the United States are unable to connect to the internet outside of school to complete coursework and actively participate in a modern education. This issue exists throughout educational settings, including K-12 schools and higher education institutions; and the lack of access disproportionately affects Native American, Black and Hispanic students, students in families with low incomes, and students in rural areas. When schools move into remote learning environments -- in response to a pandemic, natural disaster or other unforeseen circumstance -- the importance of internet access and the disproportionate impacts of a lack of access are exacerbated and thrust into the spotlight. Education policymakers and stakeholders throughout the country are eager to expand internet access for students, and many states have developed innovative and noteworthy methods to pursue broadband expansion and increase access to the internet. A variety of overlapping and interconnected barriers can result in a lack of internet access for students. This Policy Brief will introduce three unique digital divides that may prompt different policy solutions: divides caused by an absence of availability of local broadband infrastructure, the lack of affordability of an adequate internet subscription and unequal access to devices that can adequately connect to the internet. The brief also provides an overview of the impact on students when they are not able to access the internet, a summary of the scope of these digital divides and policy solutions worth consideration for each of the three digital divides.
