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

'workers on the ground primarily today's education' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'is cosseting kids' is the wordplay.
I cannot really understand how this works, but
'is' is present in the answer.
This explanation may well be incorrect...
