Deductions & credits

Can I ask a clarifying question?

My child (age 17), has earned income of $1,614 (W2) from a part-time job, AND un-earned income of $3100 from  Div/INT, total income combined is below the $12,950.  He is required to report, however, my question is:

 

1. Does he have to file his own return because he has both earned+unearned income, and/or

2. Can i report this on my return, although there is no way to report his $1,614 W2 income.

 

Appreciate it.
