While PRS does not require specific courses or any information about curricula, a certain number of credits in basic categories are required to earn a PRS diploma. It is totally up to you to decide how your child will earn those credits.
The PRS diploma requirements and recommended courses are fairly typical and modeled on what public schools require and what colleges expect to see. However, if your child is interested in attending college, it is a good idea to contact several possible colleges to ask what they look for on a transcript. If not, you should base course choices on what will be best for your child.
