A lot of high school students earn college credit before graduating high school. Several avenues for doing this are available to homeschooled students and a lot of students graduate high school as homeschoolers with several college credits or even a two-year AA degree to their name.
Advanced Placement (AP) courses are a popular option in schools. Part of the reason for their popularity is that high schools get higher ratings if they have more of their students take AP exams and higher ratings can lead to more funding. Note that some ratings aren't even based
Many parents, especially those of high school students, wonder if they need to use accredited curriculum or an accredited program, but accreditation applies to schools, not curriculum. There is no such thing as an accredited textbook, but there are accredited schools that use a variety of textbooks or other resources.
What is accreditation?
Accreditation means that an accrediting agency has reviewed all aspects of the operation of a school; it has examined its facilities, its policies, its faculty and student manuals, etc., has interviewed its faculty and administrators, and has given its approval to the school's program of instruction, operations, and facilities. Accreditation gives a guarantee that the school meets certain standards.
