Interpreter Certification

You depend on your in-house interpreters and bilingual staff to deliver meaningful access to your limited-English customers. You need to be assured of the proficiency of your team’s bilingual and interpretation skills. You may also need to test before you bring on a new hire to ensure his or her fluency in English and a second language.

Test your staff to ensure and attest to fluency.


Tests delivered annually in more than 50 languages

The advantages of LanguageLine® Testing℠

Our clients all have a similar goal: to mitigate the risk of misunderstandings and costly mistakes. To do this, they must be able to depend on the fluency of their bilingual staff and in-house interpreters.

LanguageLine’s tests were developed internally by the industry’s top language professionals. They were then externally validated by independent experts from the most prestigious language education programs in the world.
