@GA2012MOM It’s a bit different at our school, I think, because the IB Diploma Programme is the standard curriculum-everyone takes it, except for some students taking the IBCC (who are made fun of, because many of us are a tad judgmental) and those taking only a few individual subjects (who are mercilessly razzed).
This means that unless a student reports IB scores for the entirety of his/her junior year (for EA), or junior year and fall of his/her senior year (for RD), that student will simply have no grades to report for those years.
