Traveling substitute teacher in retirement?

Cost of living while full timing varies greatly, as others have explained. Monthly site costs differ from daily ones, but you would have to plan ahead for that as not all CGs offer monthly site,and costs for electricity, (often separate fee for monthlys), dependable Internet, etc can or can't be included. Being certified to substitute varies greatly from state to state, even district to district. All require background checks, and it costs separately for each district - can't just get it done once,I don't think. Often this job is no longer done by schools but subcontracted out to private companies, district by district, so you would need to get on each list. Pay varies GREATLY district by district as well. The better the pay, the less likely you could get called - everyone wants to work there! Don't know if you have ever done sub work before, but it is NOTHING as ALL like having your own class. I taught for almost 30 years (high school) and took 5 years off in the middle to 'play mommy'. I then subbed for almost 2 years before I could get a permanent position - mostly in the same school system I had previously taught in. Students do not respond to a temporary teacher the way they do to 'their own'. It's natural. You aren't expected (and often not allowed) to actually teach. Do what the teacher left for you! You often do not get the kind of support concerning necessary discipline you would if the kids were 'yours'. You don't have a reputation - administrators don't know how you actually deal with kids. I was a known commodity, and generally had few problems, but I was still seen as 'just filling in' until the 'real teacher' came back. Add to that the idea that you want to keep on traveling every 3 or 4 months - each time you would have to start over. Bottom line, from my experience, not something I could recommend.
