Test localisation that keeps the measurement honest
Language tests, certifications and assessments adapted across languages with difficulty, fairness and constructs preserved, audio items included.
Localisation of language tests adapts exams and assessments for other languages while preserving what they measure: item difficulty, discrimination and cultural fairness. Orion Translations localises language tests, certifications and psychometric instruments in more than 25 languages, with audio items recorded natively and back-translation protocols for high-stakes use.
A mistranslated item is a broken instrument
Tests are precision tools: every item was written, piloted and calibrated to measure something at a known difficulty. Translate it like marketing copy and the calibration silently dies: the passage got easier, the distractor became obvious, the scenario reads differently in Bogota than in Boston. Scores across language versions stop being comparable, which for a certification body is an existential problem.
Our assessment work treats items as instruments: adaptation by linguists briefed on the construct, equivalence review, back-translation where stakes demand it, and documentation your psychometricians can audit. The Spanish form measures what the English form measures, provably.
What test localisation covers
| Component | Adaptation work | Equivalence control |
|---|---|---|
| Reading items | Passage difficulty matched, not just translated | Readability and construct review |
| Listening items | Scripts adapted, native audio recorded | Speech rate and timing matched |
| Multiple choice | Distractors rebuilt to keep discrimination | Item review per option |
| Scenarios / situational | Cultural contexts adapted fairly | Bias review |
| Instructions and rubrics | Precision translation | Back-translation where required |
Looking for localisation testing (LQA) instead?
If "test localisation" brought you here meaning quality assurance on localised software, that is a sibling service: native testers running your localised product to catch truncations, contextual mistranslations and layout breaks before release. It lives with app localization, software localisation and game localisation, and we will route your enquiry to the right team either way.
How much does assessment localisation cost?
Per project: item count, item types, languages and the equivalence protocol set the price, and high-stakes instruments justify deeper review than practice quizzes, which we will say plainly rather than gold-plate everything. Instrument outline to info@oriontranslations.com; itemised fixed quote within one business day, NDA first on request.
Programmes, not one-offs
Assessment programmes evolve: new forms, revised items, added languages. Item banks held in translation memory with construct notes make every cycle cheaper and keep versions aligned, the same continuous model our e-learning localization clients run for course content around their assessments.
Every language version, measuring exactly the same thing.

Frequently Asked Questions
- Adapting tests, exams and assessments for other languages and cultures while preserving what they measure: language proficiency exams, psychometric instruments, certification tests and e-learning assessments. Unlike ordinary translation, test localisation must keep difficulty, discrimination and cultural fairness intact, or the scores stop meaning anything.
- Because items measure through language: a reading passage translated more simply becomes an easier item; an idiom swapped carelessly changes what is being tested; a culturally-bound scenario advantages one population. Test localisation uses adaptation plus review against the construct, so the Spanish version measures what the English one does.
- Per project, based on item count, item types (multiple choice, essay prompts, audio items), languages and the review depth your standards require, from straightforward adaptation to full back-translation protocols for high-stakes instruments. Send the instrument outline for a fixed itemised quote within one business day.
- Yes: scripts adapted to equivalent difficulty, native voice recording at controlled speech rates through our voice-over team, and timing matched to the original so listening items stay comparable across language versions.
- Different service, related name: localisation testing checks localised software, apps and games on real screens for truncations, mistranslations in context and layout breaks. If you searched "test localisation" meaning quality assurance on a localised product, that service lives with our app, software and game localisation teams, and this page links you there.
- Yes: item banks live in translation memory with construct notes per item, so revisions propagate to every language version and new forms reuse validated items. Version control across languages is most of the long-term cost saving in assessment programmes.
- Language schools and certification bodies, ed-tech and e-learning platforms, HR teams localising selection assessments, and research groups adapting instruments across populations. Confidentiality of unpublished items is handled at the same standard as our legal work, with NDAs as default.
