Cellphone bans have little impact on academics or behavior, study finds

Cellphone bans reduced in-school phone use, but they did not immediately lead to better academic or behavioral outcomes, according to a new study by the National Bureau of Economic Research, Stanford University reported.

The national report compared schools that implemented strict phone policies and those that did not over a three-year span across more than 43,000 middle and high schools. Researchers found that the cellphone ban policies had no major impact on test scores, attendance, attention or perceived cyberbullying.
