Teal woman attains diploma (4,5)

'teal' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'woman attains diploma' is the wordplay.
I cannot quite understand how this works, but
'woman' could be 'jade' and 'jade' is found within the answer.
The remaining letters 'green' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
