This is off-topic, so please delete if you wish. I am just satisfying my curiosity.
I am curious about what is expected in terms of teaching by substitute teachers in high schools in your school district, and, if known, what the pay rate is.
I ask because I am moving into retirement here in Australia and have done some substitute teaching (called supply teaching in my state) at a local school. The pay is very good (teacher wages + extra to compensate for no holiday pay and no sick leave) and the teaching required is minimal, as I might be covering classes in any subject area on a given day (eg today I covered some Health classes, a Science class, a Marine Studies class and a Geography class). So it is largely baby-sitting.
