Declassified Documents: What exactly are we supposed to make of this extremely ancient-looking piece of paper?

A tutor sent this tremendously aged handwritten memo in his application to list with Domain of Singapore Tutoring Experts in February:

This piece of paper rightly "belongs" to the National Museum. Pasir Panjang English Primary School has long ceased to exist-there is no means through which we can confidently verify its authenticity. Besides, the memo makes no specific mention of his teaching ability whatsoever, merely praising him as a good team player. Sorry, not good enough for us.

Application Outcome: REJECTED
