You do not need a qualification in order to get a job in teaching in private schools in Poland as long as your educational background is good and your accent is not bad you will be able to find a job quite easily
You are right, but from the posts from most of the other people on this particular forum, they are simply asking about how to teach in Poland, and I am trying to give them simple advice. Obviously, if one has the educational background to teach, then that person does not need the CELTA or equivalent to teach here. But, if they do have the educational background here, they wouldn't be asking how to get a teaching job in Poland, would they?
The vast majority of teachers in private schools have at least the CELTA or some sort of educational degree. Most teachers here do not fit your profile; however, as you have rightly pointed out, there are exceptions.
So, what I am saying is not wrong at all, and it applies to the overwhelming majority of native English speakers in Poland in private schools.
That is not a compulsory requirement.
You're right, it's 2 years, not 3.
