The York City School District superintendent suggested at a meeting Monday that officials consider a policy requiring students to carry clear backpacks.
Superintendent Eric Holmes said see-through bags would allow teachers and administrators to see what students are bringing to school without spending significant time each day on searches.
There is no method of 100 percent security in schools, Holmes said.
"But we want to get as close as possible," he said.
Holmes told the school board he wants building principals and school advisory committees to discuss the proposal before an official recommendation is brought to the school board.
York City would not be the first district to implement the clear backpack policy.
The policy went into effect this week at a Pittsburgh school where a 16-year-old boy allegedly used two 8-inch kitchen knives last month to attack students and staff.
Twenty students and a security guard were wounded in the April 9 incident at Franklin Regional High School, according to the Associated Press.
The school distributed clear backpacks, donated by a local car dealership, to its students Monday, the AP reported.
A York City school experienced a disturbing incident May 6 when a first-grade student brought an unloaded gun to Jackson K-8 in a book bag.
A student saw the weapon and informed a teacher, who "quickly secured the weapon and brought it to school police officers," according to a letter sent home to parents.
The building at 177 E. Jackson St. was put on lockdown for about 90 minutes while district officials investigated.
Holmes did not immediately respond to a request for further comment Tuesday. He declined to elaborate on the proposal at Monday's meeting.
