04The subject
The subject, methods and measures and debates and bodies
The field and its scope
For emergency managers, incident commanders, continuity planners and public communicators who prepare organisations and authorities to coordinate and lead through an emergency.
Quantities and units
Methods and their limits
Each method is listed with what it assumes and where it fails.
What the field debates
Bodies that set practice, and the data they publish
Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.
05The method
From an evacuation order to a cleared zone: how compliance, mobilisation time and road capacity set the clearance time an order must allow
An order reaches a population; a share decides to leave; their departures spread over hours; the vehicles meet a road capacity; the later of the last departure and the last vehicle through the bottleneck is the clearance time, and the order has to be issued that many hours before the hazard arrives.

11Questions
Questions, answers and key terms
Is study here free?
Yes. Every course and learning material of Risk Academy, led by the Nexus Consortium, is free to study, self-paced or with a cohort. Ordinary participation has no fee; paid work, internships and fellowships are separate arrangements.
What does completing a course give me?
A completion record: the course, its version, the date and what was assessed, private by default and shared by you. It stacks into discipline, department and programme achievements. A record states what was studied and assessed and does not certify competence; it is not a licence, a professional title or an employment status.
Where do the data and the places come from?
Every faculty teaches on a twin of a real place built from open data; each layer carries its provider, licence and date, and every result on the Academy states its source. Maps and figures are indicators for teaching, never an assessment of a place.
How do I take part beyond the courses in preparedness, emergency and crisis management?
Form a competence cell of three to seven people, study a shared pathway, take a supervised assignment in the National Working Groups, or bring a cohort from your institution. For organisations.
