Montgomery County Public Schools will update its student cell phone policy to include a stricter ban for high schoolers. High school students, however, could use their phones during lunch and between classes, according to MCPS. When the new school year starts next month, MCPS will go “bell to bell” with no cell phones in all schools, including high schools. “That’s something that I just think we just need to be aware of, particularly in the high schools,” Jawando said. How the cell phone policy worksUnder the policy that began last school year, MCPS uses “cell phone cubbies” in classrooms where students can store their phones.
