Based on Volleyball age Categories, generally the age groups are as follows: 
14U: Athletes born between September 1, 2009 and Dec 31, 2010 (16 months) 

The focus of the 14U Program is to further develop skills that can be performed under relatively easy and stable conditions where athletes can both build and demonstrate consistency, control, and precision. The goal in these age groups is to start (for new athletes) and to continue (for returning athletes) to develop the ability to maintain these skills when the athlete is under pressure, conditions change, or demands increase. The 6 vs 6 game is also introduced creating the need to learn team systems and position specialization. (LTAD, Volleyball Canada)

In an effort to incorporate Long Term Athlete Development (LTAD), Volleyball Nova Scotia will make Tripleball the official competition format for the 14U age category until March 1 (first half of the season). The main catalyst for Volleyball Nova Scotia’s recommendation of Tripleball is the increased probability of creating a rally. Building up rallies and experiencing success early on is an integral part of learning and enjoying the game of volleyball.
