Hi Ronda!
Here is a ray of sunshine for you!
In California, 16-17 year olds need a teacher for education only. That means that although they require teachers for three hours of required on set education when school is in session, they do not require the teacher to remain on set to provide welfare when school is not in session (i.e. weekends, holidays or summer vacation).
That means that your child can work all summer long (assuming he will be on summer break from school) without being required to have a California Certified Studio Teacher present on set.
If you can schedule your project around summer break, you'll have plenty of time to dip your toe in the acting pool. Hours of work are still limited, and you will still need an entertainment work permit/coogan account, etc.
For more info on CA Law, click on the rules and laws tab above, then choose California from the drop down list and hit "Go". Everything you need to know is on that page including a summary of the rules that you can print out.
GOOD LUCK!
