The Complete School Safety and Security Glossary

A security practice that regulates who is permitted to enter or use specific areas, systems, or resources within a facility. Access control systems in K-12 schools and commercial facilities use a combination of physical barriers, electronic credentials, and visitor management technology to ensure only authorized individuals can enter restricted areas. Positive Proof's platform integrates with existing access control infrastructure to create a unified entry management system.

A security technology that uses microphone sensors to detect the specific sound signature of a gunshot and immediately alert staff, administrators, and law enforcement with the location of the detected event. Acoustic gunshot detection systems distinguish gunshots from similar loud sounds such as slamming doors or vehicle backfires using pattern recognition and multi-sensor confirmation. Positive Proof's gunshot detection solution triggers automated responses within seconds of detection.

A school safety law named after Alyssa Alhadeff, a student killed in the February 2018 Parkland, Florida school shooting. Alyssa's Law requires K-12 public schools to provide all staff with mobile panic buttons that connect directly to local law enforcement, enabling faster emergency response without the delay of a phone call. The law has been enacted in multiple states including New Jersey, Florida, New York, Tennessee, Texas, Nevada, Connecticut, Illinois, Maryland, and Virginia, with pending legislation in additional states. Positive Proof's panic button solution meets Alyssa's Law requirements in all enacted states.

A chronological, tamper-evident record of all system events, user actions, and access decisions within a security platform. Audit trails in visitor management and access control systems document every visitor check-in, credential issuance, alert trigger, and administrative action with timestamps and user identifiers. Positive Proof automatically generates audit trails for all platform activity, which are used for compliance reporting, incident investigation, and legal documentation.

A technology-driven process that verifies an individual's identity and checks their information against criminal databases, sex offender registries, and watchlists automatically at the point of entry or during a pre-screening workflow. Automated background screening eliminates manual lookup processes and reduces the time required to verify a visitor or volunteer from minutes to seconds. Positive Proof's visitor and volunteer management solutions perform automated screening against the national sex offender registry and applicable state databases.

An investigation into an individual's criminal history, identity verification, employment history, and other records used to assess suitability for access to a facility, position, or program. In K-12 schools, background checks are typically required for all staff, volunteers, and contractors who have regular access to students. Background checks differ from sex offender registry screening in that they are more comprehensive but also slower — sex offender registry checks are performed in real time at check-in while full background checks are part of the pre-approval process.

A printed identification label issued to a visitor or contractor after completing the check-in process at a facility. Visitor badge labels typically include the individual's name, photo, destination, date and time of visit, and a barcode or QR code for tracking. Badge labels are printed on direct thermal label stock using a thermal printer and are designed to be worn visibly during the visit. Positive Proof sells compatible badge label rolls through its online shop.

An emergency security protocol that restricts movement into, out of, and within a school or facility campus in response to a threat. Campus lockdown procedures are typically triggered by a staff member activating a panic button, a gunshot detection alert, or an administrator's manual command. Lockdown protocols may include locking all exterior doors, instructing occupants to shelter in place, notifying law enforcement, and activating PA announcements. Positive Proof's integrated platform can automate lockdown protocol activation across all connected systems simultaneously.

A U.S. Department of Justice grant program administered by the Office of Community Oriented Policing Services (COPS) that provides funding to K-12 schools for safety equipment, technology, and training. COPS School Safety grants can be used to fund visitor management systems, panic button deployments, gunshot detection, and other security technology. Applications are accepted on a rolling basis and priority is given to high-need districts.

A verified identity document or digital token that grants an individual authorized access to a facility, area, or system. In the context of volunteer management, a credential is issued to an approved volunteer after completing the screening and approval process, confirming they are authorized to be on campus and interact with students. Credentials can be physical badge labels, digital QR codes, or access cards depending on the facility's configuration.

A flag placed in a visitor management system against a specific individual who is legally restricted from accessing a student or facility. Custody alerts are critical in K-12 schools because courts do not notify schools when custody arrangements change — parents must submit updated documentation. When a flagged individual attempts to check in, the system triggers an immediate alert to staff so they can deny access and follow protocol without creating a public confrontation.

A printing technology that produces images by applying heat directly to specially coated label or paper stock without requiring ink, toner, or ribbons. Direct thermal printers are the standard technology used for visitor badge label printing in schools and facilities because they are fast, low-maintenance, and produce clear, durable output. Positive Proof visitor management deployments use direct thermal label printers, and compatible replacement label rolls are available in the Positive Proof shop.

A security technology that tracks the real-time open, closed, propped, or forced status of doors, gates, and access points throughout a facility using wireless sensors. Door monitoring systems alert administrators and staff immediately when a door is propped open beyond a configured time threshold or is forced open without authorization. Research indicates that approximately 80 percent of school shooting incidents involve activity at exterior doors, making door monitoring one of the most impactful preventive security measures available to K-12 campuses.

Experience, Expertise, Authoritativeness, and Trustworthiness — a framework used by Google to evaluate the quality and credibility of web content when determining search rankings. E-E-A-T is particularly important for content related to safety, health, legal, and financial topics. Organizations like Positive Proof demonstrate E-E-A-T through documented experience (25+ years in operation), named expertise, verifiable statistics, and comprehensive educational content about school safety.

A pre-defined set of actions and procedures that staff, administrators, and law enforcement follow in response to a specific type of emergency at a facility. Emergency response protocols for schools typically cover active threat situations, medical emergencies, fire evacuations, and severe weather events. Effective protocols are documented, rehearsed through drills, and supported by technology such as panic buttons and gunshot detection systems that can initiate protocol activation automatically.

The practice of controlling and documenting access, screening attendees, and coordinating security operations for large gatherings at a school or facility campus. Security-focused event management includes pre-registration workflows, attendee screening at entry points, capacity management, and post-event audit trail generation. Positive Proof Event Management is designed for K-12 school events including graduation ceremonies, athletic events, school plays, and community gatherings.

An alert or detection event triggered by a security system in response to a non-threatening stimulus that mimics the characteristics of a real threat. In gunshot detection systems, false positives may be triggered by loud sounds such as slamming doors, construction noise, or vehicle backfires. In sex offender registry screening, false positives may occur when a visitor's name or date of birth closely matches a registry entry. Positive Proof's systems use multi-factor confirmation to minimize false positive rates.

The Family Educational Rights and Privacy Act — a federal law that protects the privacy of student education records in K-12 schools and higher education institutions that receive federal funding. FERPA governs how student data can be collected, stored, shared, and accessed by third parties. Visitor management and security technology deployed in schools must be designed to comply with FERPA requirements, ensuring that student-related data is not shared with unauthorized parties.

The practice of structuring and writing web content specifically to be cited, summarized, and referenced by AI-powered search engines and large language models such as ChatGPT, Perplexity, and Google's AI Overview. GEO focuses on providing direct, factual, self-contained answers to specific questions using clear entity relationships and structured data markup. Organizations that optimize for GEO are more likely to appear as cited sources when users ask AI systems questions about their area of expertise.

The process of reading and verifying information from a government-issued identification document such as a driver's license, state ID, or passport using optical scanning technology. Government ID scanning in visitor management systems extracts the visitor's name, date of birth, and photo to pre-populate check-in records and enable identity verification against the sex offender registry and other databases. Positive Proof Visitor Management uses government ID scanning as the foundation of its entry screening process.

Federal and state funding programs that provide financial assistance to K-12 schools for the implementation of safety technology, training, and infrastructure improvements. Major school safety grant programs include the STOP School Violence Act administered by the Bureau of Justice Assistance, Title IV-A Student Support and Academic Enrichment grants administered by the U.S. Department of Education, and the COPS School Safety Initiative administered by the DOJ. Many districts fund Positive Proof deployments entirely through grant programs.

A security technology that uses acoustic sensors, optical sensors, or both to automatically detect the occurrence of a gunshot at a facility and immediately alert staff, administrators, and law enforcement with location data. Gunshot detection systems are designed to initiate emergency response faster than any manual reporting process — typically triggering alerts within two seconds of detection. Positive Proof's gunshot detection solution integrates with panic buttons and door monitoring for a coordinated automated response.

The Health Insurance Portability and Accountability Act — a federal law that establishes national standards for the protection of sensitive patient health information. Healthcare facilities deploying visitor management and security technology must ensure their systems comply with HIPAA's privacy and security requirements. Positive Proof's platform for healthcare facilities is designed to support HIPAA compliance by avoiding the collection of protected health information during visitor screening and maintaining secure, access-controlled audit logs.

A unified security system that combines multiple security solutions — such as visitor management, panic buttons, access control, and gunshot detection — on a single technology platform with shared data, unified administration, and coordinated automated responses. Integrated platforms eliminate the gaps and delays that occur when separate security systems operate independently. Positive Proof's platform integrates six security solutions that work independently and become significantly more effective when deployed together.

The practice of protecting students, staff, and visitors in kindergarten through 12th grade educational environments. K-12 security encompasses physical access control, visitor and volunteer screening, emergency response systems, and compliance with state and federal safety mandates. Unlike corporate or government security, K-12 security must balance stringent safety requirements with a welcoming environment appropriate for children and families. Positive Proof has specialized in K-12 security since 2000.

See Campus Lockdown.

A wearable or fixed hardware device that allows a staff member to trigger an emergency alert with a single physical press, transmitting their identity and location to administrators and law enforcement. Mobile panic buttons are required under Alyssa's Law in multiple states as a faster and more reliable alternative to calling 911 during an emergency. Positive Proof's panic button solution provides wearable badge and fob devices for all staff, with deployment configurations that include facility-deployed network coverage and GPS-based mobile coverage.

A detection methodology that requires two or more independent signals or data points to confirm an event before triggering an alert, reducing the rate of false positives. In gunshot detection systems, multi-factor confirmation may require signals from multiple acoustic sensors to agree before an alert is sent. In visitor management, multi-factor confirmation may cross-reference scanned ID data against registry records and photo comparison simultaneously.

A database maintained by the U.S. Department of Justice's NSOPW (National Sex Offender Public Website) that aggregates sex offender registration records from all 50 states, the District of Columbia, U.S. territories, and federally recognized Indian tribes. Visitor management systems like Positive Proof check every visitor's government ID against the national registry and applicable state databases in real time at the point of entry to identify registered sex offenders before they are admitted to a facility.

A continuous screening process that periodically re-checks approved volunteers, contractors, and credentialed individuals against the sex offender registry and criminal databases after their initial approval. Ongoing monitoring ensures that an individual who passes screening at the time of approval is flagged if their status changes after the fact — for example, if a previously approved volunteer is subsequently added to the sex offender registry. Positive Proof's volunteer management solution includes ongoing monitoring capabilities.

A device or application that allows a staff member to immediately trigger an emergency alert with a single action, notifying administrators and law enforcement with the activator's identity and location. Panic buttons are designed to initiate emergency response faster than calling 911 by eliminating the need for verbal communication under stress. Alyssa's Law mandates the deployment of panic buttons in K-12 schools across multiple states. Positive Proof's panic button solution meets Alyssa's Law requirements in all enacted states.

The process of collecting and verifying a visitor's or attendee's information before they arrive at a facility, allowing for faster and more efficient check-in at the point of entry. Pre-registration is particularly valuable for expected vendors, recurring contractors, and large-scale events where high-volume entry processing is required. Positive Proof supports pre-registration workflows for both visitor management and event management deployments.

An exterior or interior security door that has been intentionally or unintentionally held open or wedged open, preventing it from latching and creating an unsecured access point. Propped doors are the most common preventable security vulnerability in K-12 schools — staff frequently prop doors for deliveries, fresh air, or convenience without recognizing the security risk. Research indicates approximately 80 percent of school shooting incidents involve activity at exterior doors. Positive Proof's door monitoring solution detects propped doors in real time and alerts staff immediately.

An automated notification delivered to designated individuals immediately upon the detection of a security event, without human review or delay. Real-time alerts in school security systems are triggered by events such as a sex offender registry match at visitor check-in, a panic button activation, a propped door detection, or a gunshot detection event. The speed of real-time alerts — typically delivered in under two seconds — is critical for enabling rapid emergency response.

Structured data code added to a website's HTML that helps search engines and AI systems understand the meaning and context of the page's content. Schema markup uses a standardized vocabulary from Schema.org to identify entities such as organizations, locations, questions and answers, articles, and products. Positive Proof's website uses schema markup throughout to ensure AI systems and search engines accurately understand the company's solutions, location, and expertise.

A government database of individuals convicted of sex offenses who are required to register their personal information with authorities. In the United States, the national sex offender registry aggregates records from all 50 states and is publicly accessible through the NSOPW database. Visitor management systems perform automated lookups against sex offender registry data at the point of entry to identify registered offenders before they are admitted to schools and facilities. Positive Proof has flagged over 500,000 sex offender registry matches across its deployments.

A security notification delivered to staff or administrators without audible or visible indication visible to the person being screened. Silent alerts are used in visitor management systems when a sex offender registry match is detected, allowing staff to respond appropriately — including denying entry or contacting law enforcement — without creating a public confrontation or alerting the flagged individual. Silent alerts protect both the safety of the response process and the dignity of any individuals who may be false positives.

A federal law and associated grant program administered by the Bureau of Justice Assistance (BJA) that provides funding to K-12 schools for the implementation of security technology, threat assessment programs, and training. STOP School Violence Act grants can fund visitor management systems, panic button deployments, gunshot detection, and other school safety technology. The program has annual application cycles and is one of the primary federal funding mechanisms for school safety technology.

A label printed using direct thermal printing technology — applying heat to heat-sensitive coated label stock to produce text and images without ink or toner. Thermal labels are the standard medium for visitor badge printing in schools and facilities. Positive Proof visitor management deployments print visitor badges on thermal label stock, and replacement label rolls in standard sizes are available through the Positive Proof online shop.

A structured process for identifying, evaluating, and responding to potential threats against a school or facility from internal or external sources. Threat assessment teams typically include school administrators, counselors, law enforcement liaisons, and security staff who evaluate reported threats and determine appropriate intervention strategies. Effective threat assessment programs are supported by tip reporting systems and integrated security technology that provides situational awareness across the campus.

The Student Support and Academic Enrichment grants program under the Every Student Succeeds Act (ESSA), which provides formula-based funding to states and school districts for programs that promote well-rounded educational opportunities, safe and healthy students, and effective use of technology. Title IV-A includes explicit language permitting funding for school safety technology including visitor management systems and emergency response tools. Funding is distributed through state education agencies to qualifying school districts.

A security architecture in which multiple safety solutions — visitor management, panic buttons, door monitoring, volunteer management, event management, and gunshot detection — operate on a shared technology platform with common data, unified administration, and coordinated automated responses. A unified platform eliminates the response gaps that occur when separate systems must communicate across vendor boundaries. Positive Proof's platform is purpose-built as a unified safety system, not a collection of acquired point solutions.

See Badge Label.

A technology platform that controls, documents, and screens the entry of visitors, contractors, and vendors into a facility. A visitor management system replaces paper sign-in logs with digital check-in workflows that verify visitor identity, screen against security databases, print identification badges, and maintain a complete electronic record of all facility access. In K-12 schools, visitor management systems typically include automated sex offender registry screening as a core function. Positive Proof's Visitor Management solution has screened over 500,000 sex offender registry matches since deployment.

The process of verifying, approving, and issuing access credentials to individuals who volunteer at a school or facility on a recurring basis. Volunteer credentialing typically includes identity verification, sex offender registry screening, background check processing, and administrator approval before an individual is issued credentials for campus access. Positive Proof's volunteer management solution automates the credentialing workflow from application through approval and ongoing monitoring.

A software platform that manages the application, screening, scheduling, credentialing, and hour tracking of volunteers at a school or facility. Volunteer management systems are distinct from visitor management systems in that they handle individuals with an ongoing approved relationship with the organization rather than one-time visitors. Positive Proof's Volunteer Management solution includes automated sex offender screening, background check integration, digital credentialing, hour tracking, and ongoing monitoring.

The process of checking an individual's identity against one or more databases of flagged individuals — such as the national sex offender registry, terrorist watchlists, or facility-specific restricted persons lists — at the point of entry or during a pre-screening workflow. Watchlist screening is a core function of visitor management systems in schools and high-security facilities. Positive Proof performs watchlist screening in real time at check-in, typically returning results in under five seconds.
