The European Racquet Stringers Association (ERSA) was founded in the Summer of 2001 as a partner corporation of the United States Racquet Stringers Association. After one and one-half years, we decided to become an association instead of a corporation and separated from the USRSA. We have now changed and expanded the tests we were using with the USRSA. The new tests are updated with relevant questions, and offering more certifications including tennis, badminton, and squash with more levels up to Master Pro Tour Stringer.
