Articulating my value/what I do to my target audience.

My current statement is:
I help hard-working teenage students achieve the grades they’re truly capable of by training them in the skills and strategies of exam performance and effective study, so they achieve amazing results with less stress.
However, I market to the parents.
So I wonder, should my value articulator statement be actually aimed at them and their worries/pain points?
E.g. I take away parents’ worry about how hard their teen’s working or whether they’ll get the grades they truly could, by training students in ….
But I feel this is a bit disjointed as I my solution/method isn’t by working with the parent.
Any feedback gratefully received 🙂
