Connecticut is committed to ensuring scalable, high-performance, cost-efficient broadband to its public schools and libraries. The Connecticut Commission for Educational Technology (Commission), created in 2000, serves as the educational technology advisor to schools, libraries, and institutions of higher education and started with a mission to connect public schools and libraries to the internet. The Commission created and oversees the Connecticut Education Network (CEN), the first among -- and one of only a few -- state networks in the country to connect every district to fiber. CEN connects virtually every institution of higher education as well as 62% of libraries in the state, in addition to serving as the primary public resource in K-12 broadband provision and support in the state. This case study finds that Connecticut's approach to addressing broadband for schools was to build a regional statewide network to provide ubiquitous and equitable service and connect all districts as well as other educational institutions such as regional education centers, libraries, colleges, and universities. Additionally, Connecticut was the first in the country to connect all districts to an all-optical network in 2005 and then in 2013 upgraded all districts to a 1Gbps handoff standard. CEN has set a high bar for internet service in the state and region. This study briefly touches on Connecticut's statewide K-12 education broadband network, network performance, network upgrade process, off campus access, district implementation, and future plans.
