If your teen has completed a high school course prior to the 9^th grade, it is possible to show this course on his/her high school transcript.  For your personal recordkeeping, be sure to document the course by noting materials used (books, videos, supplemental readings), scope and sequence of the course (what concepts were covered), method of evaluation, and credits earned for the course.  In order to receive high school credit, all course materials must be high school level.  To find out if the materials are high school level, contact the publisher of the curriculum/book, search out a review by Cathy Duffy, or glean information from homeschool catalogs regarding the grade level of materials.
