This was pretty- much risk management 101 for teachers (identifying risks, assessing likelihood of occurrence and severity of consequences and then prioritizing control measures)
The emphasis was less on student safety than on the risks associated with not covering the syllabus adequately and not achieving appropriate standards of achievement
The guts of the presentation was about having clear documentation (an audit trail) identifying:
What item must be taught
What level of achievement is acceptable?
How can we justify our choices?
How did we set standards of achievement
How did we measure learning achievement?
