If a player is registered for a section for which the player is ineligible by grade, then MCA will take 1 of 2 steps. If MCA thinks a player has been registered intentionally so as to play up or down in a grade-inappropriate section (in the hope of either stronger or weaker competition), then (without notification) MCA will move the player to a grade-appropriate section. (MCA might also impose punitive measures.) Conversely, if MCA thinks a player has been registered accidentally with a discrepancy that, given the player's designated grade, renders the player ineligible for the player's selected section, then (without notification) MCA will pair the player in a section according to whichever is higher: the designated grade or the selected section. For example, a player designated as a 3rd grader but registered in a HS-&-MS or 9th-grade section, will remain in the HS-&-MS or 9th-grade section; conversely, a player designated as a 9th grader but registered in an ES or 3rd-grade section, will be moved to a HS-&-MS or 9th-grade section. Why? Because MCA considers it wiser to err on the side of accidentally letting a player in a low grade play against players in a higher grade or grades, than of accidentally letting a player in a high grade play against players in a lower grade or grades. To prevent your player from being paired in an incorrect section (by grade) because of a registration error, please review both the registration-confirmation email MCA sent you & the Wallcharts below.
