Her school district in Easton, Pa., decided to cancel classes on Election Day after Andrioitis and other parents brought up fears that violence could break out at the schools' polling places.
There's no official tally of how many schools will be closed nationwide on Nov. 8, according to the National School Boards Association. But in various districts from New Jersey to Nebraska, officials have canceled classes, or moved polling out of schools to other buildings this year.
In North Carolina, another battleground state, the Johnson County school board opted to close schools after local election officials warned that turnout would be higher than ever.
"They're expecting more than we've ever had," Nathanael Shelton, director of communications for Johnson County schools, told NBC News. "Just to err on the side of caution, we decided to close those schools."
The fears stem from a tense election season in which a Hillsborough, North Carolina, GOP campaign office was firebombed and voters have made a habit of holding up posters threatening violence against the candidates. A USATODAY/Suffolk University poll released Wednesday found that 51 percent of likely voters are concerned about the possibility of Election Day violence.
Even federal officials have expressed apprehension as Election Day approaches, with one telling NBC News that authorities were particularly worried about the "I'm a patriot and if it comes to it, I'll grab my weapons and defend my flag" Trump supporters.
But the idea of Election Day school closures isn't new or unique to this election. In New York state, many districts have been closed for years, including those in New York City, the largest school district in the United States with 1.1 million students.
Supporters point to student safety as the number one reason for closing schools, citing the high number of outsiders flowing in and out of buildings. Many also believe closing schools helps voter turnout and emphasizes the importance of civic duty to students.
