This is more commonly known as Red Shirting in Kindergarten - just an earlier form of reclassifying. The school cut off is what it is.

According to ALL US School districts the regular grades for 2014/15 academic year spring/summer births:
Spring/Summer 2000 = 9th grade (2018)
Spring/Summer 2001 = 8th grade (2019)
Spring/Summer 2002 = 7th grade (2020)

Cutoffs vary by distict so Oct-Dec birthdays may be in different grad years but Spring/Summer birth months are black and white.
