Why is the birthday used to determine playing groups rather than school grade?
Chronological age is used in all SBMSA sports because it is the most fair. True, some children are a grade ahead or a grade behind but these are exceptions and the Association must use rules benefiting the majority of the players. If we played by grades, it could on occasion have players of three or four ages together. SBMSA would have no control of which grade a student is in, but our rules would allow for an age span of only twenty-four months for most leagues.
