Graduation requirements vary from state to state. Contact the school counselor and ask for information on graduation requirements for your child. You should have a conference with the counselor concerning the credits completed, credits needed and other related information, such as college admission requirements, grade point average, advanced placement courses and dual credit courses.
I am a student and i have recently had my IEP meeting and my councler told me that in order to graduate you are required to have NO LESS that 24 credits. If you have more that looks better on your transcript but that is the required amount!!
