Also offered: Certified Back translations
Back translation can improve the reliability and validity of research in different languages by requiring that an independent translator translating back into the original language verify the quality of a translation. Original and back translated documents can then be compared.
Back translation usually costs the same as the initial translation (called ***forward translation***) . Though it may seem like an avoidable cost , the expense is well worth the investment, given the cost one may have to incur on account of errors going unchecked.
