I have been informed today that I have been successful in passing the US Racket Stringers Association Master Racket Technician accreditation. I successfully completed two written theory tests covering all types of stringing techniques along with a separate paper about racket technologies. Additionally a timed practical test covering grommet replacement, upsizing of a grip and restringing with natural gut. Further reassurance that your racket is in safe hands with Hillfield Racket stringing.
