Translation quality can be assessed using clearly defined criteria. What matters is not only whether a translation is grammatically correct, but also whether it conveys the content completely, accurately in technical terms, consistently in terms of terminology and appropriately for the target audience. Depending on the type of document, legal, technical or regulatory requirements may also need to be taken into account.
Professional companies therefore assess translations using structured quality criteria rather than the personal language preferences of individual people. This makes translations objectively comparable, comprehensible and continuously improvable.
The most important assessment criteria
- Content accuracy: All information from the source text is transferred completely and correctly, without any loss of meaning or misinterpretation.
- Terminological consistency: Technical terms, product names and company-specific wording are used consistently throughout.
- Linguistic quality: Grammar, spelling, punctuation and readability comply with the linguistic standards of the target language.
- Style and target audience: The tone, writing style and wording are appropriate for the target audience and comply with the company’s style guides and language guidelines.
- Formal and technical requirements: Layout, numbers, units of measurement, references and industry-specific or regulatory requirements are transferred completely and correctly.
✅ Real-world example
A medical technology company reviews the translation of an instructions for use document. Although the text is grammatically error-free, two approved technical terms are used inconsistently. In addition, a safety-critical warning has been worded too weakly. Only a structured quality review makes these deviations visible and enables targeted correction before the document is published.
✅ Good to know
Many companies now use AI-supported quality checks to assess translations objectively. These checks make it possible to identify terminology errors, inconsistencies or formal deviations much more quickly than through exclusively manual review. However, for safety-critical, legal or regulatory content, these checks do not replace final expert approval by qualified translators or subject-matter experts.
