Martinsburg Inline Hockey supports four divisions in its program. Squirts ages 5-8, Minors 9-13, Majors 14-18, and adults 18 and over. Youth playing in the Major division can also play in the adult league. Ages are based on the age of the child on 1 September for the Fall season and will carry through to the Spring season. For example, a child age 8 on 1 Sep will play in the Squirt division for both the Fall and Spring season even if he/she turns 9 between the two seasons.
