Hi LeAnna, I totally understand where you are coming from. I am graduating my first homeschool student this year and I had to learn everything from square one. One thing that helped me was to understand that the transcript is (usually) a condensed one page document consisting primarily of your student's ACADEMIC achievements.
In terms of college admissions, you may provide other items like book lists, course descriptions or complete portfolios at the request of the institutions you are applying to, but the transcript itself containing the students GPA is the main component required, along with official ACT/SAT scores. Some colleges will offer you a template to follow, but I have submitted my own transcript and it has been accepted without any problem. This is, however, my individual experience having applied to many institutions here in southeast Georgia.
I used a book called "Setting the Record Straight" by Lee Binz, along with other resources on the HomeScholar website, and many other resources on the internet to create my own version of a transcript that worked for my daughter's record. It will be a little different for each child and you will find what works best for you and your children as you start creating your own transcripts.
I tried to upload the transcript we have submitted to the colleges my daughter is interested in so that you could get an idea of what should go on a transcript, but I could not get the PDF to upload. Mine is VERY simple, though. Noting fancy, but it got the job done. She has been accepted to every school she applied to, has been offered scholarships, and has been invited by several to compete for full tuition/room and board.
I hope this helps. I know I needed all the help I could get when I started.
Blessings,
Letha
