Without access to an authenticator app on their phones, some teachers said they can’t even log into their work emails, in a robust social media discussion in response to an informal poll by Education Week.

The poll asked if teachers should be included in their school’s cellphone policies. More than half the 1,668 respondents said teachers don’t need any rules to govern their cellphone use, while 31% believed that such restrictions should exist. Fifteen percent said “it depends.”

Meanwhile, nearly 350 readers of the Savvy Principal newsletter weighed in on whether they have rules for how teachers can use their phones during the school day. Forty-nine percent said yes.
