President Joe Biden’s push for more employers to require vaccines is likely to accelerate an already-growing trend in schools.

In the past month, the number of states requiring teacher vaccinations has jumped to 10, including the District of Columbia, according to a new analysis we conducted at the Center on Reinventing Public Education.

Those include roughly a third (31) of the districts in our review of 100 large and high-profile school systems. And Los Angeles Unified’s high-profile move to require eligible students to get vaccinated suggests vaccine mandates won’t be confined to school employees.

Rising vaccination rates are good news for the country’s students. They increase the chances schools will be able to keep them safe, and keep them learning, all year and in person as much as possible.

But they won’t totally eliminate other challenges school systems are likely to face. Clarifying quarantine rules, and supporting high-quality instruction for students who are forced to quarantine or isolate because they’ve tested positive or been exposed to the virus, remains a critical task for state and school district leaders.

Right now, the amount of time students can expect to spend in quarantine if they are suspected of being exposed to the virus, and the amount of instruction they can expect to receive, varies a lot depending on where they live.
