Editing Grade (climbing) (section)

===Other notable systems===

* '''Canadian Ice'''.  Canadian ice climbs quote both the [[#Canadian Winter Commitment Grade|Canadian Winter Commitment Grade]], with Roman numerals 1–7 for the "overall" challenges and risks, and a "technical scale" that uses Arabic levels 1–7 for the hardest movements. Other grades can be provided to reflect the mixed climbing (M-level), the thickness of the ice (R-level), and the fragility of the structure (X-level).  In practice, Canadian Ice "technical grades" are equivalent to the WI-grade, but omit the "WI"; a typical route could be graded as III-4.<ref name=CAI/><ref name=Ari/>
* '''New England Ice''' (NEI). A system was developed in the 1970s in [[New England]] that used NEI levels 1 to 5 (and a later level of 5+) to grade ice routes, which in effect equated to the WI-grades of WI1 to WI5 (and NEI 5+ at WI6).  The NEI levels are considered to be slightly "harder" than the equivalent WI-grades. Following the international trend, the WI-system is now commonly used in New England.<ref name=FoHGrading/><ref name=Ari/>
