Question 1

How do you verify a grading scale?

Accepted Answer

We read the primary source — a national qualifications framework, a university regulation or an awarding body's published table — record the exact bands and points, and store the source URL with the date we checked it.

Question 2

How often is the data re-checked?

Accepted Answer

Every scale carries a last-verified date. Our build check warns when a scale has not been re-verified within twelve months, so stale data is flagged rather than silently served.

Question 3

What do you do when a scale cannot be verified?

Accepted Answer

We leave it out. Accuracy over coverage means a scale only appears once it can be traced to an official or primary source.
