I don't think it will be for a while, probably not this year it seems. They have only recently put through the first bunch of people (myself included) from the order of merit list of applicants who applied in 2009. More positions have been offered for September and November.
The group that applied this year (applications closed a while back) have been told that their next stage will be delayed as the Academy is running at full capacity at the moment.
Best thing to do if you want to know is to try and get ahold of someone from AsA recruitment.
