Not how many entered — who is inside right now
An access record is a number; a presence list is an answer. This page describes how that answer is produced and when it should not be trusted.
One pool
Everyone in the building sits in the same list; which group a person belongs to is the badge on the row.
- Student
- Staff
- Visitor
- Contractor
Arrived, not arrived, late
Everyone who passed the gate and appears to be inside; the row shows the entry time and the gate name.
Expected today but no signal yet; the list is shortest at the start of the first lesson.
Those who passed after the lesson started; the delay in minutes is calculated, not estimated.
Occupancy and the three-colour band
Occupancy is the ratio of people inside to the capacity the institution entered; the institution sets the capacity, we do not invent it.
- Green: you are comfortably below capacity.
- Amber: capacity is close; a queue starts at the gate.
- Red: capacity is exceeded; restricting entry is the institution's decision.
Occupancy by zone
- Floor
- Block
- Canteen
- Yard
- Sports hall
Peak hour and gate queues
Hourly density is measured per gate; the hour at which a single turnstile is not enough comes out of the report, not out of a guess.
Separating staff and visitors
When a student count is requested, staff, visitors and contractors are removed from the list; the number states which groups it includes.
