Peto your organisation has to understand that it is competing against 3 other integrated school, all of which are happy to release their employment figures. If you don't release them then wannabes will suspect none of your graduated courses have been employed and it's not worth bothering coming to your school!
If they are employed then say so and pat yourselves on the back on a job well done (i personally don't get your argument of over inflation of employment figures)
Ah well
