Fortifying the Foundation
Level 1 — Physical Assessment℠ (The Shell). On-site evaluation of every exterior and interior physical safety zone — doors, fencing, lighting, access points, and more.
← Back to The StandardLevel 1 structure
Two Assessments. One Complete Picture.
Level 1 is divided into two independent questionnaires — each generating its own SafeSchool REPORT℠. Together they evaluate the full physical envelope of your campus: everything outside and everything inside.
Exterior Assessment
Evaluates everything outside the building envelope — perimeter, access points, fencing, lighting, parking, signage, and visitor management.
- Perimeter fencing & gate controls
- Main entry & visitor access points
- Parking lot visibility & layout
- Exterior lighting coverage
- Signage, wayfinding & boundary marking
- Exterior surveillance camera placement
- Bus loading zones & drop-off control
- Campus perimeter dead zones

Interior Assessment
Evaluates the inside of every building — hallways, classrooms, common areas, door hardware, and structural containment capacity.
- Classroom door hardware & lock capability
- Hallway sight lines & blind spots
- Interior access control & badging
- Common area monitoring coverage
- Emergency egress routes & signage
- PA & mass notification systems
- Front office visibility & control
- Cafeteria, gym & auditorium protocols

Level 1 input — campus type
No Two Schools Are the Same.
Campus architecture determines what a physical assessment must cover — and what safety responses are actually possible. POSI recognizes 9 distinct campus types, each with different risk profiles, security needs, and response requirements.
Campus type is collected once during school profile setup and informs how your Level 1 results are scored and contextualized. A lockdown protocol designed for a single-building school is operationally irrelevant on an open-air campus. Assessment without architecture is assumption.
Urban campuses
Type 1
High-Rise School
High complexityShared building, street-level entry. Elevator/stairwell bottlenecks, shared access points, coordination with building management required.
Type 2
Standalone Urban — No Fence
High complexityDoors open directly to public sidewalk. No buffer zone. Door-level access control is the only perimeter defense.
Type 3
Standalone Urban — Fenced
ModerateDefined perimeter boundary. Layered security options available — effectiveness depends on entry point management.
Traditional campus designs
Type 4
Single Building, Indoor Hallways
Highest incident rateClassic American schoolhouse. Highest frequency of shooting incidents in 2024. Hallways channel threats rapidly to all classrooms.
Type 5
Multiple Attached Buildings
ModerateConnected structures with shared interior corridors. Larger footprint with similar hallway vulnerability to Type 4.
Type 6
Detached Buildings, Covered Hallways
ModerateSeparate buildings connected by covered walkways. Response can be compartmentalized by building — a tactical advantage.
Open & distributed designs
Type 7
Detached Buildings, Open-Air Paths
High complexityStudents move outdoors between buildings every ~45 minutes. Traditional lockdown doctrine is largely ineffective. Movement protocols required.
Type 8
Individual Classroom Buildings
Scenario-dependentEach classroom is standalone with dual exterior exits. Faster targeted evacuation possible. Perimeter control is the priority strategy.
Type 9
Mega-Campus
Zone-based planningShopping mall scale — theaters, pools, gyms, food courts. Requires sector-level emergency protocols. School-wide responses create confusion.
Special consideration — Portable & modular classrooms
Present on any campus type. Physically separated from the main building, often disconnected from PA systems, difficult to monitor, and lacking structural protections of permanent construction. Assessed as a distinct security zone in every Level 1 evaluation.
