What Are the Advantages of Language Tests?
Language proficiency testing helps to recruit people who can communicate effectively in the language you are testing. As language proficiency is so relative among people, objective language proficiency tests in human resources processes are necessary. The person you are going to test might understand the language very well but might not speak well or s/he might speak fluently but might have insufficient grammar knowledge. In this way, you can measure the candidate's language proficiency in the subjects you need.
