Stone Academy has provided students with a career-oriented business education for more than a century. Its rich history dates back to 1864 when it was founded as the United States College of Business. Later the school became known as Stone School of Business. In 1988, as a result of a merger with The Academy for Business Careers, the school became Stone Academy. In 2002, following a merger with Goodwin Institute, Stone Academy opened a branch campus in Waterbury.
Stone Academy in Waterbury is a testing site for the RMA, NPA, and CNA examinations.
