This is an old thread, but I’m going to add a reply, anyway, in case someone else is searching with questions like I was doing when I found this thread. 🙂
I have two graduates and a current 9th grader. We’ve always schooled year round for the most part. We do take a summer break, but it’s shorter than the typical summer break, and then we take other breaks throughout the year as needed. Consequently, my girls have always had subjects that overlap from year to year… still doing math hanging over from 9th grade while beginning 10th grade science, for example.
I still did their transcripts by date, but I recorded the subjects in the year in which the BULK of the work was done. So that 9th grade math was still recorded under the year for 9th grade, even though she was finishing it up after beginning 10th grade work in other subjects. This pattern continued all the way through high school. In fact, I’d have to look at my oldest dd’s transcript to remember which year I put Home Ec under (actually, I think there’s another preferred name for that now), because she was learning new skills and reading homemaking- and cooking- and nutrition- etc. type books all the way through high school. But whatever year she learned how to make complicated costumes for her sister’s ballet production, AND made her first quilt, is the year I officially gave her credit for that elective subject. (I’m pretty sure it was 11th grade, now that I think about it.)
So doing it this way would satisfy those colleges that might require specific “school year” dates for those of us who don’t follow the public school calendar.
