This person's three characteristics in greatest need of development? Statement?

Hi all,
I am drafting a reference letter for my lecturer, after that he will edit it again. He is my referee for my application for a master program.

Please help me make clear this statement "What are this person's three characteristics in greatest need of development? ". I understand that "what are three characteristics of this person that greatly need to be developed.''

Thank you.

Kim Yen

You are correct. It means, what are the three characteristics the person has that MOST need to be developed?

or

Discuss three characteristics of the person that are in greatest need of development?

Many thanks Hannah Grierson. My job done :)
