It is the policy of the ACC that students competing in ACC sport must be under 19 years of age as of 31st December. Students who have turned 19 years of age are not permitted to participate in ACC sport. It is also ACC policy that student participation is limited to "secondary school students" and that the minimum level for participation is enrolment in Year 7. Schools may apply for exemption to this policy but only under certain conditions.

Age Cut Off Dates

Cut off date 31 December 1996: As of 2010 all ACC carnivals will use multiple reference age cut off dates. This is to bring the ACC age group cut off dates in line with the new school start age which was introduced for students born in 1997.  The new age cut off dates are as follows:

• Age group calculation 1 = 31^st December: for those born on or before the 31^st December 1996 i.e. born before 1997: these students will continue to use this age reference date for future years.
• Age group calculation 2 = 30^th June: for those born after 31^st December 1996 i.e. born after 1996: these students will continue to use this age reference date for future years.
• E Division will maintain the old cut off date of 31^st December for all students as this carnival does not have U13 events.

To preserve record status the previous records under old age group cut off systems of 1 October pre 1996 and 31 December pre 2010 have been maintained.
