Ad Astra does not provide diplomas. 

Ad Astra is not a school and is not legally able to graduate your student. 

As a parent, you are the legal authority over your student's education, to include thier graduation, in the state of Virgina. You will be the one to graduate your student from your own named homeschool entity under your own authority. You will need to order and provide your student with a diploma. The good news is, you are not the first person to do this and there are plenty or resources and options available to meet your needs and preferences. Remember, like a birth certificate or marriage liscence, this is a professional document that will be meaningful to your student for the rest of their life in a variety of situations. Please be sure to provide them with a document that respectfully and professionally reflects their completion of compulsory education with any honors and special accomplishments notated appropriately. 

Here is a link to one of many companies which provide the service of producing your high school graduation diplomas.
