Re: Teacher Training
I would advise from personal experience to get some time in a classroom before you make the leap into teacher training. In my opinion its a real vocation and has its stresses and frustrations like any other career. Subbing or supervision is easy enough to come by if you make some contacts in schools in your area. Only problem is your current job obviously but maybe you could take some holidays?
Something else to consider is that many secondary teachers are employed as 'part-time' for a number of years while waiting for permanent positions to come available, and there is no security in this. Even though they will have the hours and after school responsibilities of permanent teachers, they are in fact paid by the hour and are officially unemployed when on school holidays..Halloween, Christmas, Easter etc.
On the flip side, hours are better than in other industries and hols are great. Some people love it, but be sure before you commit to the training.
