Based on Volleyball age Categories, generally the age groups are as follows: 
18U**: Athletes born between September 1, 2004 and Dec 31, 2005 (16 months)
17U*: Athletes born between September 1, 2005 and Dec 31, 2006 (16 months)

* Athletes born September 1-December 31 of the previous year, on a current CCAA or USports volleyball roster, will not be permitted to play in the 17U age class.

**For 2023 VC Club Nationals & VNS Provincials, 18U Age Category ONLY:
A team roster for the 18U category can include 2 athletes born from Jan 1 - August 31, 2004, with the following restriction: Athletes are NOT permitted to be part of any USport, CCAA or other Post-Secondary volleyball program for the current season (Sept 2022-May 2023)

For boys' volleyball in Nova Scotia, the age categories are limited to 14U, 16U and 18U. As such we combine the 17U and 18U age groups.

The focus of the 17U and 18U Program is to optimize fitness preparation, volleyball-specific skills, and position-specific skills and to commit to a pathway which will also optimize performance. Individual and position-specific training is provided to players with training volumes and intensities gradually raised to high levels. Volleyball skills are performed under a variety of competitive conditions during training. More complex team systems are learned. Training should be position specific. (LTAD, Volleyball Canada)
