Chose to avoid starting school? (7)

I believe the answer is:
elected
'chose' is the definition.
(electing is a kind of choosing)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for elected that I've seen before include "Chosen for office" , "Chosen by vote" , "Appointed" , "made a choice" , "In a position" .)
