Become a Certified Dry Stone Waller, or increase your level! Dry Stone Wall Certification is a must have for the professional waller or landscaper, and the best way for a homeowner and hobbyist to quickly increase in skill. Each test involves dismantling and rebuilding a specified section of wall in a 7 hour time limit. Level 3 and 4 also include untimed feature builds. Each level increases substantially in difficulty. Becoming a certified waller will help you build better and faster. As more and more clients become educated on the benefits of using certified wallers, it is becoming a needed credential for professionals. Those who become Level 2 certified, can then take the instructors certification course and teach stone walling. The Dry Stone Walling Association of Great Britain (DSWA) is the certifying organization. The DSWA is the first and oldest dry stone certification scheme in the world, and has become the international standard for dry stone walling.
