YES! For any Absolute Beginner class, you may purchase a single class card for the first session of each term. You simply pay the balance before the 2nd class meeting. This does not apply to any Beginner and Open Level classes, which are available only by single-class or 10-class cards.
If you would like your child to try a class, s/he may try the first class of the semester for free. Simply fill out a 92Y Harkness Dance Center Try-A-Class form and turn it into the 2nd Floor Dance Center office before the class meets. If your child enjoys the class and would like to continue, registration must be completed within 48 hours of the trial date. Because class sizes are limited and many classes fill, only registration ensures a place in class. Participation in Try-A-Class does not guarantee placement.
