Yes—the version of the MoCA test matters because language, culture, and scoring rules can change what the score means. The Montreal Cognitive Assessment (MoCA), a brief cognitive screening tool, should use an official version suited to the person's language and that version's instructions. Testing in a familiar language can reduce avoidable language barriers, but translation alone does not guarantee a fair comparison. MoCA Cognition also describes the test as a screening tool, not a stand-alone diagnosis.

Choosing the right language version
MoCA Cognition says the paper test is available in nearly 100 languages. It directs users to follow the administration and scoring instructions packaged with the official PDF being used, according to its official MoCA FAQ. This means a clinician should use the matching official form whenever possible.
Translating questions informally during an English-language test may change their difficulty, meaning, or scoring. Availability does not prove that every translation performs identically. Mapi Research Trust warns that listed translations may not have completed full linguistic validation and could require more work before use in a study, as noted in its MoCA instrument record.
Why word-for-word translation can fail
Some moca tasks depend on features of a particular language. A literal translation may preserve the words while losing the skill the item was designed to measure. A 2012 Chinese-language adaptation found that three existing versions sometimes misunderstood the original purpose of items.
Some instructions also sounded unnatural or were difficult for people with little formal education to understand. The researchers replaced English "F" word fluency with naming four-legged animals because phonemic fluency did not work the same way in Chinese, according to the International Journal of Alzheimer's Disease study. That change illustrates the difference between translation and adaptation. A sound adaptation aims to preserve the cognitive demand of a task, even when the words or examples must change.
Does the usual cutoff still apply?
Not automatically. The frequently cited threshold of 26 or below came from the original validation study involving English- or French-speaking Canadians aged 65 or older. In that study, the threshold identified mild cognitive impairment with 90% sensitivity and 87% specificity. Those results do not establish that the same cutoff works equally well in every language or cultural group.
A score should be judged against evidence and instructions for the particular version and population, not treated as a universal measurement. education adjustments can also differ. MoCA Cognition says some versions use the standard correction, while others use a different correction or none at all. The administrator should apply only the rule specified for the version given.
How fair are the available versions?
The evidence is mixed. A systematic review identified 86 culturally distinct MoCA versions but found substantial differences in how they were adapted and which items were changed. The authors concluded that more research was needed before the MoCA could be considered fully cross-culturally fair, as reported in Neurological Sciences.
A translated result may still provide useful screening information. However, scores from different versions may not be directly interchangeable, especially when their tasks, education rules, or validation populations differ. This matters when following changes over time. Before comparing two scores, check whether both assessments used the same language version, administration instructions, and scoring method.
What to ask before or after testing
Before relying on a MoCA result, ask the clinician or testing service: A low score should lead to professional assessment, not an automatic dementia label. Bring the report—and the exact name or copy of the version used—to a health professional with cognitive expertise.
- Which official language version will be used?
- Is that version culturally adapted or only translated?
- Has it been studied in a population similar to the person being tested?
- Which education adjustment applies to this version?
- Were earlier tests completed with the same version and scoring rules?
