For a "translation only" request where the client elects to NOT have the translation edited by a second linguist, the project may go through one of several sample QA checks:

1. QA Review - Select projects are checked and rated by a second linguist before the project is returned to the client. The translation is rated based on specific parameters (translation accuracy, grammar, style, etc.). 
2. Language Leader Review - We have a team of in-house language leaders for our most popular language pairs. These individuals also run sample quality checks for their respective languages. This allows us to detect errors and trends and take corrective action when needed.

The above translation quality review measures are not 100% thorough and do not take the place of a full editing step. We are working on a process that allows clients to select a specific sample review level for their specific project.
