Does Khan Academy Award diplomas?

I would like to enroll my son in online classes to complete his high school classes and get his diploma through Kahn Academy. Is this option available? We live in Altoona Ia although my son goes to school in Colfax Is. He is in 9th grade..
Please let me know ASAP as he is having problems with his principle, some of his teachers and some of the other kids at school.

Thank you
Melody Dunblazier
