The school colours were dark green and yellow.
The motto then was "Patientia et Sapientia" meaning Patience and Wisdom.
I graduated from PEES in 1967, and so I do not know when exactly the crest was changed to the new colourful emblem below.
The 'new' school crest with the new motto "Each His Best" and the banner "Princess Elizabeth Estate School" over the torch.
PEES relocated from Hillview to Bukit Batok New Town in 1987 and so the 'estate' became redundant. The school was renamed Princess Elizabeth Primary School and the school crest was then revised to the current school crest.
