Stoddard-Wilkins Elementary Aptitude Test

The Stoddard Wilkins Elementary Aptitude Test (often abbreviated as S.W.E.A.T.) is a test shown in the episode of the same name.

It's most likely just a readiness test, as International Talk-Like-A-Pirate Day is September 19, far too early in the school year for a final.

The S.W.E.A.T testing day is on September the 21.
