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 and consistently in terms of terminology, and in a way that is appropriate for the target audience. Depending on the document type, legal, technical or regulatory requirements may also need to be taken into account.
Professional organisations therefore assess translations using structured quality criteria rather than the personal language preferences of individual people. This makes translations objectively comparable, traceable and continuously improvable.
Key assessment criteria
- Content accuracy: All information from the source text is transferred completely and accurately, without any loss of meaning or misinterpretation.
- Terminological consistency: Technical terms, product names and company-specific phrasing are used consistently throughout.
- Linguistic quality: Grammar, spelling, punctuation and readability meet the linguistic standards of the target language.
- Style and target audience: The tone, writing style and phrasing are appropriate for the target audience and comply with the organisation’s style guides and language guidelines.
- Formal and subject-specific requirements: Layout, numbers, units of measurement, references, and industry-specific or regulatory requirements are transferred completely and accurately.
✅ Practical example
A medical technology company reviews the translation of instructions for use. Although the text is grammatically flawless, two approved technical terms are used inconsistently. In addition, a safety-critical warning has been phrased too weakly. Only a structured quality review makes these deviations visible and enables targeted correction before the document is published.
✅ Good to know
Many organisations 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 an exclusively manual review. However, for safety-critical, legal or regulatory content, these checks do not replace final subject-matter approval by qualified translators or subject-matter experts.
