Insight lacking in education (7)

I believe the answer is:

tuition

I'm a little stuck... Click here to teach me more about this clue!

'education' is the definition.
(tuition is a kind of education)

I don't understand how the rest of the clue works.

(Other definitions for tuition that I've seen before include "(Individual) instruction" , "Personal coaching" , "Lessons" , "Schooling" , "Training" .)

I've seen this clue in The Hindu.
