Certification Test Overview:
At the Stone Trust you can acquire Dry Stone Walling Association of Great Britain (DSWA-GB) Level 2 Certification. Wallers who pass this test will earn Level 2 Intermediate Waller Certification.
The second of four levels of certification offered by the DSWA-GB, Level 2 stands as the globally recognized professional standard. DSWA-GB certification is the oldest and best administered certification for dry stone wallers. The credentials are recognized throughout the world.
As a matter of Stone Trust policy, you must have earned a Level I certificate before you apply to take a Level 2 test. In addition, participants must be respectful of other examinees, the examiners, and the test site. You are expected to work safely and to avoid distracting others. Be sure to read the policies for participation in Stone Trust events.
During a Level 2 test, each candidate will strip down and rebuild a section of wall totaling 27 square feet which incorporates a square wall end, also known as a cheek end. Twenty-seven square feet equates roughly to a wall 4 feet 6 inches tall and 6 feet long. While the square footage is measured on one face, the test candidate strips out and rebuilds the cheek end along both adjacent faces. Your finished test stint must measure at least 42 inches high. You must complete the rebuild within a period of 7.5 hours. If you do not finish, you do not pass.

Tips for Success:
- Know the requirements
- Arrive at least ½ hour early to settle in (examiners can answer questions before test starts)
- This is not your highest quality work, it is the work you can produce in 7.5 hours
- Sort the material as you strip out (generally not more than 30 min)
- Strip out the wall so there is equal amounts of stone on both sides
- Through stones should be on by ½ the allowed time (3.5 hours)
- Sort face stones by size, keep copes, hearting, and throughs separated.
- The end of the wall should be vertical (no batter).
- Examiners look for the cheekend to be properly tied back into the wall
- Good Line, straightness, and even wall faces, are important at this level
- Heart very solidly under throughstones
- Pin (heart) between and under each face stone
- Be familiar with setting up batter frames
- No running joints up the wall end are allowed
- A large, solid, end cope is important.
- The cheekend is marked higher than any other category of the test.
Most wallers, even very experienced ones, need to do a lot of preparation in order to pass level 2. The Level 2 test has an average 50% pass rate. Don’t expect to be able to pass this without preparation. If you have questions please contact us.
- Most people who successfully pass Level II have built at least 5 to 10 cheek ends on the clock
- Take a Pre-Test (practice test with no evaluation).
Workshops aimed at preparation for Level II Certification
All levels of certification consist of taking down and rebuilding a specified amount of wall in 7.5 hours. The walls are built in the presence of certified examiners and must meet the minimum required score to pass. All tests are graded on a pass/fail system. Each part of the test wall is numerically graded, and must meet or exceed a minimum score to pass. The test wall as a whole must also meet a minimum score to pass. The required sections and minimum scores vary for each level of certification. See the page for each level for detailed information and example mark sheets.
The 7.5 hour test time does NOT include a mandatory half hour lunch break. After the test is complete The Center needs to be tidied up and you may chose to review your work with the examiners. This is in addition to the 7.5 hour test and often lasts 1.5 – 2 hours.
Test participants must be respectful of other examinees, the examiners, and The Center. Working safely and not distracting others is important. Be sure to read the policies page.
General Information About Certification:
The Stone Trust provides access, to and administers, the Dry Stone Walling Association of Great Britain (DSWA-GB) certifications at its Training Center in Dummerston VT, and occasional other sites in the USA. The certification consists of four levels, each applied for and tested separately: Initial (Level I), Intermediate (Level II), Advanced (Level III), and Master Craftsman (Level IV).
The certifications are designed to ensure that dry stone wallers achieve the highest standards of craftsmanship for their experience and training level. The difference in standards for dry stone walling between good and bad work is significant. Hiring certified wallers provides a basis of quality work.
The DSWA’s certifications have become the world wide standard for evaluating wallers’ proficiency and quality. The certifications began in the early 1970’s in Great Britain as a way to evaluate a waller’s skill, promote correct structural techniques, and help clients determine the capabilities of prospective wallers.
The Stone Trust administers all four levels of certification. Certification tests are hands-on demonstrations of the wallers’ capabilities. At each level the test walls are evaluated and scored by certified DSWA examiners. Registration for each test must be submitted 6 weeks prior to the test date. Tests are available to all individuals, amateurs and professionals alike.
Certification tests are rigorous and challenging at all levels. All test candidates should be familiar with the correct structural techniques involved with building a dry stone wall. Test candidates must start at Level I, and progressively work their way up. Even very talented wallers typically take at least 4 years to over a decade to reach Master Craftsman.
Nearly all wallers will need to prepare for certification by taking workshop courses, pre-tests, and practicing on their own.
