Primary teacher here . Whilst there’s a shortage of subs, there’s also quite of shortage of any long term work or permanent posts . Because you have a family , you will be limited geographically too, I presume ?
I’d think long and hard about spending quite a lot of money with Hibernian , being honest .
The main messages from the replies here seems to be that becoming qualified and registered (not easy in themselves) are no guarantees of permanent jobs or a career in teaching which is kind of what is needed here to be honest with bringing a family over and becoming settled.
This is a big concern and really the more ideal situation would be to jump into work pretty much right away after I return (in any field really) but not sure that will be possible.
Securing part-time work while completing the process of becoming qualified to teach or any other kind of long term professional qualification would be necessary.
I am fine with taking a few steps back to get ahead again later but of course a guarantee of a decent profession/income is essential too.
