Our policy is to have all of our translations done by native speakers, by which we mean translators who have grown up speaking the language into which they translate. We also consider it important to use translators who live and work in a country where that native language is spoken as an official language. This is because native speakers who move abroad often find that their command of their own language becomes 'contaminated' if they hear a foreign language around them everyday. Living and working in an environment where the relevant language is actually spoken is the best way to ensure that the language and terminology in a translation are correct.
