Clunk! Well done Terril.
Like I said, Walsh Manor is the SO berthing for Saint Hill. The "school"
is the grooming school for the Cadet Org and the Sea Org.
I got your point about the catchment area and the kudos that St Hill has. Nevertheless, in my time, it was unusual for overseas people to come to the SO in EG with their children.
These children are either simply children of regular overseas recruits as you described, or there is something new going on where the SO is actively recruiting foreign immigrants. The UK has had a huge influx of people from countries like Poland and the SO would view immigrants, legal or illegal, as good raw meat and presumably would have to have catered for their children.
The string to pull is the percentage.
70% of the 19 children don't have English as their first language. That's 13 out of 19 children not native English-speaking! This is unusual for the SO in EG.
But all that is, for now, a minor issue unless it reveals employment of illegal immigrants or unethical employment of EC citizens.
The major points are the others that I listed, which indicate an inadequte education and child exploitation, along the lines of Melbourne.
Strings are being pulled. More data is needed by anyone with recent knowledge of Walsh Manor.
