in some cases the risks and commitment level—of the route. The <a href="/wiki/First_ascent" title="First ascent">first ascensionist</a> can suggest a grade, but it will be amended to reflect the consensus view of subsequent ascents. While many countries with a strong tradition of climbing developed grading systems, a small number of grading systems have become internationally dominant for each type of climbing, which has contributed to the standardization of grades worldwide. Over the years, grades have consistently risen in all forms of climbing, helped by improvements in <a href="/wiki/Climbing_technique" title="Climbing technique">climbing technique</a> and <a href="/wiki/Climbing_equipment" title="Climbing equipment">equipment</a>. In <a href="/wiki/Free_climbing" title="Free climbing">free climbing</a> (i.e. climbing rock routes with no aid), the most widely used grading systems are the French numerical or sport system (e.g. f7c+), the American YDS system (e.g. 5.13a), and latterly the UIAA scale (e.g. IX+). These systems are focused on technical difficulty, which is the main focus of the lower-risk activity of <a href="/wiki/Sport_climbing" title="Sport climbing">sport climbing</a>. The American system adds an R/X suffix to <a href="/wiki/Traditional_climbing" title="Traditional climbing">traditional climbing</a> routes to reflect the additional risks of <a href="/wiki/Climbing_protection" class="mw-redirect" title="Climbing protection">climbing protection</a>. Notable traditional climbing systems include the British E-grade system (e.g. E4 6a). In <a href="/wiki/Bouldering" title="Bouldering">bouldering</a> (i.e. rock climbing on short routes), the most widely used systems are the American V-scale (or "Hueco") system (e.g. V14), and the French "Font" system (e.g. 8C+). The Font system often attaches an "F" prefix to further distinguish it from French sport climbing grades, which itself uses an "f" prefix (e.g. F8C+ vs. f8c+). It is increasingly common for sport climbing rock routes to describe their hardest technical movements in terms of their boulder grade (e.g. an f7a sport climbing route being described as having a V6 <a href="/wiki/Crux_(climbing)" class="mw-redirect" title="Crux (climbing)">crux</a>). In <a href="/wiki/Aid_climbing" title="Aid climbing">aid climbing</a> (i.e. the opposite of free climbing), the most widely used system is the A-grade system (e.g. A3+), which was recalibrated in the 1990s as the "new wave" system from the legacy A-grade system. For "clean aid climbing" (i.e. aid climbing equipment is used but only where the equipment is temporary and not permanently hammered into the rock), the most common system is the C-system (e.g. C3+). Aid climbing grades take time to stabilize as successive repeats of aid climbing routes can materially reduce the grade. In <a href="/wiki/Ice_climbing" title="Ice climbing">ice climbing</a>, the most widely used grading system is the WI ("water ice") system (e.g. WI6) and the identical AI ("alpine ice") system (e.g. AI6). The related sport of <a href="/wiki/Mixed_climbing" title="Mixed climbing">mixed climbing</a> (i.e. ice and <a href="/wiki/Dry-tooling" title="Dry-tooling">dry-tool</a> climbing) uses the M-grade system (e.g. M8), with other notable mixed grading systems including the Scottish Winter system (e.g. Grade VII). Pure dry-tooling routes (i.e. <a href="/wiki/Ice_tool" title="Ice tool">ice tools</a> with no ice) use the D-grade prefix (e.g. D8 instead of M8). In <a href="/wiki/Mountaineering" title="Mountaineering">mountaineering</a> and <a href="/wiki/Alpine_climbing" title="Alpine climbing">alpine climbing</a>, the greater complexity of routes requires several grades to reflect the difficulties of the various rock, ice, and mixed climbing challenges. The International French Adjectival System (IFAS, e.g.TD+)–which is identical to the "UIAA Scale of Overall Difficulty" (e.g. I–VI)–is used to grade the "overall" risk and difficulty of mountain routes (with the gradient of the snow/ice fields) (e.g. the <a href="/wiki/1938_Heckmair_Route" class="mw-redirect" title="1938 Heckmair Route">1938 Heckmair Route</a> on the <a href="/wiki/Eiger" title="Eiger">Eiger</a> is graded: ED2 (IFAS), VI− (UIAA), A0 (A-grade), WI4 (WI-grade), 60° slope).

In 1967, the "Welzenbach scale" formally became the "UIAA scale" for rock climbing (or "UIAA Scale of Difficulty") with Roman numerals I–VI, and a "+" and "−" to refine each level. The UIAA also incorporated proposals made in 1943 by <a href="/w/index.php?title=Lucien_Devies&action=edit&redlink=1" class="new" title="Lucien Devies (page does not exist)">Lucien Devies</a> [<a href="https://fr.wikipedia.org/wiki/Lucien_Devies" class="extiw" title="fr:Lucien Devies">fr</a>] and the <a href="/w/index.php?title=Groupe_de_Haute_Montagne&action=edit&redlink=1" class="new" title="Groupe de Haute Montagne (page does not exist)">Groupe de Haute Montagne</a> [<a href="https://fr.wikipedia.org/wiki/Groupe_de_haute_montagne" class="extiw" title="fr:Groupe de haute montagne">fr</a>] on a broader "Scale of Global Assessment" for alpine climbing (the French Alpine System), and created the "UIAA Scale of Overall Difficulty" by assigning Roman numerals I–VI to the six adjectival levels (e.g. F, PD, AD, D, TD, and ED) of the French system. The UIAA also incorporated a "Scale of Difficulty in Aided Climbing" for <a href="/wiki/Aid_climbing" title="Aid climbing">aid routes</a> with the levels: A1, A2, A3, A4, and (later) A5. In 1978, the UIAA added the VII (seventh grade) to its "UIAA scale", implying that the scale was open-ended, a concept formally adopted in 1985.<a href="#cite_note-CAI-2">[2]</a> By the 1980s, French guides had customized the "UIAA scale" beyond V+ with the letters "a", "b", and c" (e.g. V+, VIa, VIb, etc.).

The two scales were summarised as "Plaisir Grades" and aligned in a UIAA table where French grades 1–6a aligned with "UIAA scale" grades I–VI+; beyond that level, the two systems diverged and for example, French 7a+ equates to UIAA grade VIII and French 9a equates to UIAA grade XI.<a href="#cite_note-CAI-2">[2]</a> In America, a version of the Welzenbach Scale was introduced for rock climbing in 1937 by the <a href="/wiki/Sierra_Club" title="Sierra Club">Sierra Club</a>, which in the 1950s was further adapted into the Yosemite Decimal System that added a decimal place to the class 5 grade (e.g. 5.2, 5.3, 5.4, etc.), and which by the 1960s was again amended to introduce the letters "a", "b", "c", and "d" after 5.9 to further refine the levels (e.g. 5.9, 5.10a, 5.10b, 5.10c, etc.).<a href="#cite_note-CAI-2">[2]</a> While individual countries developed their own rock climbing grading systems, the American system, French system, and latterly the "UIAA scale" became popular internationally (with the American and French dominating sport climbing). The UIAA "Scale of Overall Assessment" dropped its six Roman numbers in favor of the six adjectival grades of the French Alpine System (to avoid confusion with the "UIAA scale") and dominated alpine climbing grading, while the UIAA "Scale of Difficulty in Aided Climbing" – amended and expanded in Yosemite in the 1990s as "new-wave" grades – dominated aid grading.<a href="#cite_note-CAI-2">[2]</a> <div class="mw-heading mw-heading2"><h2 id="Free_climbing">Free climbing</h2>[<a href="/w/index.php?title=Grade_(climbing)&action=edit&section=2" title="Edit section: Free climbing">edit</a>]</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">See also: <a href="/wiki/List_of_grade_milestones_in_rock_climbing#Single-pitch_routes" title="List of grade milestones in rock climbing">List of grade milestones in rock climbing § Single-pitch routes</a>, and <a href="/wiki/List_of_grade_milestones_in_rock_climbing#Multi-pitch_routes" title="List of grade milestones in rock climbing">List of grade milestones in rock climbing § Multi-pitch routes</a></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Adam_Ondra_climbing_Silence_9c_by_PAVEL_BLAZEK_2.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/a/ab/Adam_Ondra_climbing_Silence_9c_by_PAVEL_BLAZEK_2.jpg/220px-Adam_Ondra_climbing_Silence_9c_by_PAVEL_BLAZEK_2.jpg" decoding="async" width="220" height="147" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/a/ab/Adam_Ondra_climbing_Silence_9c_by_PAVEL_BLAZEK_2.jpg/330px-Adam_Ondra_climbing_Silence_9c_by_PAVEL_BLAZEK_2.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/a/ab/Adam_Ondra_climbing_Silence_9c_by_PAVEL_BLAZEK_2.jpg/440px-Adam_Ondra_climbing_Silence_9c_by_PAVEL_BLAZEK_2.jpg 2x" data-file-width="2301" data-file-height="1536" /></a><figcaption><a href="/wiki/Adam_Ondra" title="Adam Ondra">Adam Ondra</a> on the <a href="/wiki/Sport_climbing" title="Sport climbing">sport climbing</a> route <a href="/wiki/Silence_(climb)" title="Silence (climb)">Silence</a>, the hardest free climbing route in the world and the <a href="/wiki/List_of_grade_milestones_in_rock_climbing#Redpointed_by_men" title="List of grade milestones in rock climbing">first-ever</a> at 9c (French), 5.15d (American YDS), and XII+ (UIAA).</figcaption></figure> The two main <a href="/wiki/Free_climbing" title="Free climbing">free climbing</a> grading systems (which include the two main free climbing disciplines of <a href="/wiki/Sport_climbing" title="Sport climbing">sport climbing</a> and <a href="/wiki/Traditional_climbing" title="Traditional climbing">traditional climbing</a>) are the "French numerical system" and the "American YDS system".<a href="#cite_note-CAI-2">[2]</a> The "UIAA scale" is still popular in Germany and across parts of Central Europe.<a href="#cite_note-CAI-2">[2]</a> Many countries with a history of free climbing have also developed their own free climbing grading systems including the British E-grade system and the Australia/New Zealand "Ewbank" system.<a href="#cite_note-CAI-2">[2]</a> The evolution of <a href="/wiki/List_of_grade_milestones_in_rock_climbing#Single-pitch_routes" title="List of grade milestones in rock climbing">grade milestones</a> in traditional climbing, and latterly sport climbing (as it took over from traditional climbing as the main focus of the leading free climbers), is an important part of the <a href="/wiki/History_of_rock_climbing" title="History of rock climbing">history of rock climbing</a>.

The system is open-ended and uses only Arabic numerals (i.e. no "a", "b", "c" or "+" and "−" refinements), starts a 1 (easiest), and continues upward. Unlike many other systems (e.g. <a href="#American_YDS_grade">American YDS</a> and <a href="#French_sport_grade">French sport</a>), the Ewbank system is not solely based on the hardest technical movement on the route but also takes into account the exposure, length, quality of rock, availability of protection, and other factors. Thus, a dangerous route with easier technical climbing might get the same grade as a safe route but with harder technical climbing. The system relies on the <a href="/wiki/Climbing_guidebook" title="Climbing guidebook">climbing guidebook</a>, or word of mouth, to clarify the factors that influenced the grade.

Originally, the Scandinavian countries used the <a href="#UIAA_scale">UIAA scale</a> but its closed-end status at VI (up until 1985) led them to create their own systems, however, they align closely to the UIAA scale, particularly to grade IV.

The second, the technical grade, which is the most in use, defines the technical difficulty of the hardest movements (or sequences of movements) and is an open-ended scale that starts with Roman numerals (and a "sup." for additional refinement between numerals), up to VIsup., which is roughly VII+ (UIAA) f6b+ (French) or 5.10d (American). After VIsup., the system moves to Arabic numerals, starting at 7, and using the symbols "a", "b", and "c" for additional refinement between numerals (e.g. VI, VIsup, 7a, 7b, 7c, 8a, etc.,.).<a href="#cite_note-CAI-2">[2]</a></li> <li>Polish Cracow scale (or Kurtyka's scale).

(IFAS), 5.9 (American), 5c (French), VI− (UIAA-rock), IV (NCCS).</figcaption></figure> The IFAS system (or UIAA Scale of Overall Difficulty), also called the French Alpine System (or Alpine System),<a href="#cite_note-Rockfax-3">[3]</a><a href="#cite_note-AAJ-26">[26]</a> grades the overall difficulty of a route, taking into account the length, technical difficulties, exposure, and commitment level (i.e. how hard is a retreat).<a href="#cite_note-FoHGrading-4">[4]</a><a href="#cite_note-Ari2-34">[34]</a> The system was created by French climbers, and when the UIAA formally adopted it in 1967 they assigned Roman numerals to the six levels, which caused confusion with the <a href="#UIAA_scale">UIAA scale</a>, and thus the French shorthand for the six levels prevailed:<a href="#cite_note-CAI-2">[2]</a> F–Facile (easy), PD–Peu Difficile (not very difficult), AD–Assez Difficile (fairly difficult), D–Difficile (difficult), TD–Très Difficile (very difficult), and ED-Extrêmement difficile (extremely difficult).<a href="#cite_note-Rockfax-3">[3]</a><a href="#cite_note-FoHGrading-4">[4]</a><a href="#cite_note-AAJ-26">[26]</a> Later, a + (pronounced Sup for supérieur) or a − (pronounced Inf for inférieur) was used to indicate if a particular climb is at the lower or upper end of that grade (e.g., a climb slightly harder than "PD+" might be "AD−"), and the specific degree of the snow slopes was added (e.g. 60 degrees).<a href="#cite_note-CAI-2">[2]</a> As standards rose, the ED-grade was further expanded into ED1 (is the original ED−), ED2 (is roughly the original ED), ED3 (is the original ED+), ED4, ED5 .. etc., to denote harder levels of grade.<a href="#cite_note-CAI-2">[2]</a><a href="#cite_note-Ari2-34">[34]</a> Whilst each IFAS grade can imply certain grades of rock, ice, or mixed climbing difficulties, the UIAA warns against assuming the IFAS grade always aligns with specific rock and ice climbing grades, as the objective dangers can vary dramatically on alpine routes with similar rock and ice climbing grades. For example, the famous 1,800-metre <a href="/wiki/1938_Heckmair_Route" class="mw-redirect" title="1938 Heckmair Route">1938 Heckmair Route</a> on the north face of the <a href="/wiki/Eiger" title="Eiger">Eiger</a> has an IFAS ED2-grade even though the rock climbing is only at UIAA VI− and the ice climbing at 60 degrees (or WI-4 grade), which is more typically associated with an IFAS D-grade; this is due to the exceptional length and serious dangers of the route.<a href="#cite_note-CAI-2">[2]</a><a href="#cite_note-Rockfax-3">[3]</a> Some guidebooks have still attempted to <a href="/wiki/Alpine_climbing#Grading" title="Alpine climbing">list</a> the implied rock and ice climbing grades at each IPAS level.<a href="#cite_note-Rockfax-3">[3]</a><a href="#cite_note-ISM-35">[35]</a><a href="#cite_note-Ari2-34">[34]</a> <div class="mw-heading mw-heading3"><h3 id="American_NCCS">American NCCS</h3>[<a href="/w/index.php?title=Grade_(climbing)&action=edit&section=26" title="Edit section: American NCCS">edit</a>]</div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Craig_DeMartino_on_Zodiac_on_El_Capitan.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/9/9c/Craig_DeMartino_on_Zodiac_on_El_Capitan.jpg/220px-Craig_DeMartino_on_Zodiac_on_El_Capitan.jpg" decoding="async" width="220" height="330" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/9/9c/Craig_DeMartino_on_Zodiac_on_El_Capitan.jpg/330px-Craig_DeMartino_on_Zodiac_on_El_Capitan.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/9/9c/Craig_DeMartino_on_Zodiac_on_El_Capitan.jpg 2x" data-file-width="427" data-file-height="640" /></a><figcaption>The 16-<a href="/wiki/Pitch_(climbing)" title="Pitch (climbing)">pitch</a> <a href="/wiki/El_Capitan" title="El Capitan">El Capitan</a> route Zodiac, is graded 5.7 (American), A2+ (A-grade), VI (NCCS) with <a href="/wiki/Aid_climbing" title="Aid climbing">aid</a>;
