The state in which you live will issue the homeschooling high school diploma that you will present to your student once his or her home schooling classes have been completed.  In order to get a homeschool high school diploma, your student will have to take a test at a state facility to prove that he or she is ready to graduate high school.  Some states have rules regarding age when it comes to receiving a homeschool high school diploma.  Most states require a student to be at least 16 years old before he or she graduates high school.  There are exceptions to this rule for gifted students, however.  Anyone who is home schooled can sit for the general education test and receive their diploma if they pass the test.
