Demographic Highlights • Middle schools are significantly less likely than elementary and high schools to report less than 95% uptime. • Schools in suburban areas are significantly more likely than schools in town and country areas to report 99.9% uptime. • Schools with high instructional materials expenditures are significantly more likely to report less than 95% uptime, while schools with low instructional materials expenditures are significantly more likely to report 99.9% uptime than are schools with medium or high instructional materials expenditures.
Industry Device manufacturers could provide network specifications and implementation guidance that will lead to networks with higher availability. Chart 5.7. On average over the past year, what percentage of the school day is your instructional network up for student and teacher use? (Q23)

• School with high and very high minority percentages are significantly more likely than schools with lower minority percentages to report 95% or less uptime.
Implications Instruction A reliable network is essential in any digital environment. If students and teachers—especially teachers who are new to technology— become frustrated by unreliable access, they will soon stop using the network. It is important that the network is never down for more than a few seconds and that long periods of downtime are rare.
Policy A lack of appropriate network infrastructure inhibits the usefulness of the devices. Policymakers might want to require that local education authorities provide appropriate infrastructure and support plans for devices purchased with public funding.
Less than 95% uptime
Finance Stable and robust networks are costly. However, the opportunity cost of idle equipment and an under-utilized network is even greater. It is important that school leaders understand the financial and physical network requirements to handle the amount and types of usage needed.
