Clowns - not 100% sure that's what he said.....
Fergus - the list of schools on the CAA website are approved BY the UK CAA in accordance with JAR.
The school you mention MAY be JAA approved under the Spanish authorities - nothing to do with the UK CAA.
If the school IS approved under JAR then you will, no doubt, be able to transfer the credits when you return to UK.
This one is not the CAA's fault.
