Score high Any measurement error is ≤ 0.5 mm All planes flat and smooth All angles sharp and accurate
No noticeable error in symmetry or orientation of parts
Score mid Any measurement error is
> 0.5 mm and ≤ 1.0 mmAny plane with slight curvature or slight
roughness
Any angle with slight lack of sharpness or slight lack of accuracy
Slight error in symmetry or orientation of parts
Score low Any measurement error is
> 1.0 mm and ≤ 1.5 mmAny plane with obvious curvature or obvious
roughness
Any angle with obvious lack of sharpness or obvious lack of accuracy
Obvious error in symmetry or orientation of parts
Score zero Any measurement error is > 1.5 mm Any plane with severe curvature or severe
roughness
Any angle with severe lack of sharpness or severe lack of accuracy
Severe error in symmetry or orientation of parts

and accurate 2/3 correct and no noticeable error in
symmetry or orientation of parts
Score mid 0 2/3 correct and any plane with slight
curvature or slight roughness 2/3 correct and one or more angles with slight
lack of sharpness or slight lack of accuracy 2/3 correct and slight error in symmetry or
orientation of parts
Score low 0 2/3 correct and any plane with obvious
curvature or obvious roughness
2/3 correct and one or more angles with obvious lack of sharpness or obvious lack of
accuracy
2/3 correct and obvious error in symmetry or orientation of parts
Score zero 0 < 2/3 correct or any plane with severe
curvature or severe roughness

accuracy
< 2/3 correct or severe error in symmetry or orientation of parts
*An automatic deduction will be applied to the incorrect pattern grade with a minimum grade of 0
An incorrect pattern is defined as a pattern where the candidate has completed all three elements but one or more of the carved elements does not correspond to the required test. An incomplete pattern is defined as a carving in which one or more of the three elements has not been completed.
