I'm in a position where I can leave the country for up to a year. It will be more affordable than staying here and getting by on the dregs of supply. Also, it should free me from the agencies' finder's fee! I'm thinking of completing the CELTA and doing a combination of paid EFL teaching and volunteering in a school abroad. I am worried that it will cause problems getting work when I get back. Will I need a police check to account for this time away? Will schools view this unfavourably?
