The compass test software for aviation was developed by EPST Holland. EPST was started by a Dutch I.T chap to make a lot of money. The local university helped come up with some of the tests and the programmers wrote the software.
EPST charge on a per test basis to the end customer. Hence why Oxford training and some other users, started to charge for interviews to cover costs of the tests and to make some money themselves.
The pass bar mark is just chosen by the end customers.
I believe Each test, once completed also has the test results sent and held on EPST's servers. EPST have statistics from all over the world of the various test results.
Its purely a money making scheme and really meant for initial cadet training selection, not for those with 20 years experience changing jobs into established airlines.
