Seventh Grade Initiative (7GI)

At the Y, we understand that young people face many challenges during adolescence and need the support and compassion of parents, teachers, friends and other positive role models to navigate the often daunting journey. In fact, statistics show that seventh-grade in particular is a critical time in a young person's life when exposure to risk factors greatly increases. The Y's 7th Grade Initiative (7GI) gives kids an opportunity to learn, grow and thrive by sharing in healthy, confidence-building activities and programs in a safe setting. See our Teen page with program details.

MY Y.  YOUR Y.  New Jersey YMCAs Membership Reciprocity Program

What is the purpose of the New Jersey YMCAs Membership Reciprocity Program?
The spirit behind the reciprocity program is founded on the belief that the Y is one movement and that we want to encourage members to utilize the Y as often as they can in order to meet their health and wellness goals. Sometimes, it is more convenient for a Y member to utilize a Y in a different location when traveling, near a workplace, or in another region. This program allows active, full facility/full privilege members this flexibility to use other Y facilities and therefore also increases the value of their Y membership.

Statement of Reciprocity:  The agreement is intended to allow a member unlimited visits at another Y. When someone reaches between 8 - 12 visits (level determined by the host Y) they can call the home Y to see if that member is visiting their home Y more than the host Y. The host Y can limit the visits at that time if they have not visited their home Y as often as the host Y. The host Y can determine if they take the individual person or the entire unit into account when looking at usage.

AWAY Program

A.W.A.Y. - "Always Welcome at YMCAs." When enrolled in a YMCA, members become a part of a nationwide association. When away from home, YMCA members will be warmly welcomed by participating YMCAs. Princeton Family YMCA requirements: member visits from YMCAs within 50 miles - 6 visits per year. Member visits from YMCAs over 50 miles away - FREE up to 12 visits per year. Additional visits may be purchased for $5.
