Teachers at Lake Braddock Secondary School stood outside their own Back-to-School Night on Tuesday chanting “Let us teach!” — not over pay or class sizes, but over a new assignment that has them running weapons detection checkpoints at the school's front doors. The protest capped a rocky start to the school year across Fairfax County Public Schools, where administrators have begun requiring classroom teachers to help staff the district's growing network of security scanners.
The Lake Braddock demonstration was reported by NBC4 Washington, which described teachers arguing that operating metal detectors puts educators on the front line of potential safety threats instead of letting them focus on instruction. The same protest was also documented by The Virginia Flyover, which reported union opposition and teacher objections to the checkpoint assignments. The pushback landed just as building administrators began enforcing the new staffing requirement at the start of the 2026–2027 school year, according to that outlet.
As DC News Now reported, Fairfax County Public Schools teachers are now assigned to work metal detectors at schools throughout the division. The equipment in question is the OpenGate system, which uses two freestanding pillars to detect metallic threats such as guns and knives, according to Annandale Today.
From Pilot Program to Permanent Fixture
FCPS first rolled out a pilot of 15 OpenGate units at randomly selected high or secondary schools in April 2025, as detailed by Annandale Today. The available reporting here does not establish the program's allocation amount or funding sources.
District officials moved quickly from testing to permanent deployment after two incidents rattled the community: an April 2025 student stabbing at West Potomac High School and a February 2025 gun-possession arrest at Edison High School, per reporting cited by WJLA 7News. School board members described the West Potomac stabbing as a tipping point that shifted the district's approach from temporary trials to district-wide, permanent screening.
The expansion kept building from there. FCPS expanded weapons detection to all middle and high schools in fall 2025, according to WUSA9. Security administrators told that outlet the scanner towers themselves haven't changed — they've simply been pointed at more crowds, including students and spectators arriving for athletics.
How the Checkpoints Actually Work
Under procedures established during the 2025 pilot, students hand off their backpacks and pass through the OpenGate towers after removing only their laptops, since the dense metal components inside trigger the electromagnetic sensors, Annandale Today reported. When a secondary screening is needed, FCPS says it is conducted by security, administrators, and trained designated staff, rather than necessarily by classroom teachers assigned to checkpoint duty.
The scale of that logistical task is significant. Screening students each morning across campuses requires daily staffing, and teachers have been assigned to help operate entrance systems.
A Contract Fight Layered on Top
A Contract Fight Layered on Top The dispute over checkpoint duty arrives against the backdrop of questions about a labor agreement and its scope. The available reporting here does not establish when any agreement was ratified, whom it represented, whether it was the district's first labor contract in decades, or whether it established health, safety, and working-condition standards after Virginia law authorized municipal collective bargaining.
Fairfax's approach also stands out regionally. The available reporting here does not establish which neighboring divisions were operating metal detectors in middle schools when FCPS introduced them. According to a July 17, 2025 report from the D.C. Office of Inspector General, the District's middle and high schools uniformly employ scanners and metal detectors at entrances.
Whether Fairfax's teacher contract explicitly covers security screening assignments, and whether the district plans to hire dedicated non-instructional staff to take over checkpoint duty, remain open questions. It's also unclear how much the OpenGate system has actually reduced weapons incidents on campus since the 2025 rollout began. For now, the chants outside Lake Braddock signal that many teachers feel the answer to who should be running the scanners shouldn't be them.
