Deku Elementary

Deku Elementary is a location mentioned in.

Features and Overview
Deku Elementary is never shown in-game, but if Link speaks to Madame Aroma in the Mayor's Residence while in his Deku form, she'll assume he's a student of Deku Elementary visiting on a field trip.

Since there are few Deku residents in Clock Town, it's more likely that Deku Elementary is located somewhere in the Southern Swamp. Conversely, the school may not be race-specific, but may simply be named after the Deku, though this seems less likely.
