Tuition:

  • Ninjas may join classes at any time during the month/year pending availability.  Wait lists are always available.  Classes run on a month-to-month basis from the 1st of the month to the last day of the month.  Tuition is based upon at least 4 opportunities to attend class during that time and is set up as a recurring credit card charge on the 1st of each month.

Cancellation Policy:

  • Families must provide USA Ninja Challenge a 30-day written notice to cancel their Ninja(s)’ membership.
       This can be accomplished via email at marlborough@usaninjachallenge.com or by completing the Membership Cancellation Form available at the Ninja Front Desk.  Without this notification, your Ninja’s spot is reserved for the month with a non-refundable tuition payment.

Dress Code:

  • Ninjas must wear short-sleeved shirts with shorts/leggings with bare feet and long hair pulled back.
  • Long sleeved shirts, denim shorts with rivets, long pants/sweatpants, dresses or loose clothing, belts, drawstrings, hoods and socks, gum, candy, hats, bobby pins and jewelry represent safety hazards and are not allowed in the gym.

Make-up Policy:

Make-ups carry forward and accumulate but are limited to 3 accumulated make up classes on your account. Students unable to use the make-up classes immediately are welcome to save their make up classes for a more convenient time such as during the summer.

September 1 accounts will be reset to remove make up classes. Therefore, please be sure to schedule and use all make up classes before September 1st or you will lose them!

Make up classes may not be used towards other offerings of the gym and must be used for make-up classes.  If more than 3 classes accumulate on your account due to extenuating circumstances such as long-lasting illness or injury (supported by dr. note) or unexpected family emergencies please contact us to discuss your options.
