Up until last year, there were 3 stages to their admissions. First interview, Pre test, Common entrance. The last two stages are very clear to everyone. The first stage isn't.
There is a first interview with one of the HM's you would have stated on your registration form.(although, they say it's not important! But it is)
If they like you, you get added to the list of one of your preferred HM's. (The amount of choice you have at this point is directly related to who/how many invited you for the first interview). Usually no more than 3. But it could be just one.
The next stage is pretest
The pretest inludes an interview, a computer test, and a written essay piece of work.
Who interviews you on pre test day will be determined by who's list the candidate is on . Meaning the lucky candidate will be seeing his now HM for the second time. He already likes you, boy feels nice and relaxed, you just need to ace the tests now!
There are no more interviews after this. The final stage is Common entrance.
If you were unsuccessgul for whatever reason to get on an HM's list you will still be invited to pre test, but have no idea who will interview you, and you won't be preferred choice anyway, (although they don't tell you that! But the inference is clear) unless you somehow went under their radar but completely blew them away on pre test day. They will slot you into a gap created by someone who was on the HM's list but disappointed on pre test day.
Now they have introduced ISEB I'm not sure wether this comes before or after the first interview, but it would make a 4th layer, unless they've scrapped the first interview..I don't know.
Its very hard to explaining it all in writing, because there's a lot of unspoken stuff going on in the background and you have to read between the lines,like the form that says, you don't have to state your preference, but then you find out it would have been wise to do so. This is my only gripe with the school. Otherwise it's a fantastic school!
Any by the way, at that first interview, be aware that parents sit in on it too, not just the boy. At least Radley make that very clear.
Please feel free to PM if you want to.
