The school consistently achieves elite academic results, ranking 7th out of over 1,100 Washington elementary schools, with proficiency rates in core subjects that are 9-13 points above the district average and significantly higher than nearby schools like Issaquah Valley Elementary and Clark Elementary.

Endeavour achieves these outstanding results efficiently, performing better than schools with higher per-student spending, such as Challenger Elementary.
