OP your kid is great exactly the way that he is in exactly in the way that he’s doing it!
I’ve read a lot of scholarship applications, over the years, and I can pick out when someone is being phony or exaggerating their ECs.
Your child has learned the qualities of being a good employee.
He is:
-punctual
-takes directions well,
-is reliable,
-is consistent,
-has a strong work ethic,
-and adapts well to his environment.
The colleges and universities are there to not only educate, but also to provide good employees with those work ethic skills for the workforce and their employers.
Your child has already learned what those colleges hope will evolve in their students. Tell him to keep up the good work as he is a decade ahead of most graduating seniors.
I agree with @blossom. I think his ECs are FINE. He sounds like an upstanding young man. I believe he will do well, no matter where he goes, because he already has those skills that elude a lot of young people.
