Just a note about the International House in Krakow. I was interviewed for their May 14th course and accepted. I came to Krakow and dropped into the IH to pay the deposit. I was told that the course may not run after all, and that they would call me "in a few days". That was almost three weeks ago, and not a word.
Here's a little update, as I was in the same(ish) boat as you. I booked and paid my deposit for the July CELTA course at IH Krakow, only to find out that they're no longer affiliated with IH Worldwide and that CELTA will not allow them to host a course there, why I do not know, though . Anyhow, I wrote to CELTA direct and here is an extract of the reply I received via email a couple of days ago:
"IH Krakow are no longer affiliated with IH Worldwide and now go by the name of Instant English and the May CELTA course currently being run in Krakow is actually being administered by IH Katowice as (what Cambridge ESOL term) an "off-site" course. This is a short-term arrangement only but one that is fully authorised and supported by Cambridge ESOL.
From 21st June onwards CELTA in Krakow will be available at the British Council."
I am very impressed that you have managed to find work anyhow and as I speak a little Polish (very little) I am wondering if I really must do this dreaded CELTA course as I've heard nothing but scare stories about how difficult it is?
If anyone wishes to share their experience of the CELTA course I am all ears!
