DD completed tenth grade a few weeks ago. She is taking an SAT subject test on August 24th. For registration purposes, is she is in tenth or eleventh? TIA.

Eleventh

10th I think. That’s what i did for registration and it looked correct when I was done.

I would put 11th because by August she would have technically finished 10th grade already. After finishing classes for a grade level, I would put the grade level that I’m going into whenever it asks for it.

11th

College Board lists the August test date as the first date of the "2019-20 SAT Administration Dates ". So it seems clear to me that it’s what year a student is in for the 2019-20 school year. In this case, 11th.
