Educational Testing Services is a private non-private organisation that conducts educational research with an emphasis on testing. It is the same organisation that conducts the TOEFL examination which is accepted at more than 11,000 institutions around the globe. 

There are more than a million international students enrolled at American universities and colleges, however, to get an admission in these institutes students must meet certain criterions. One such criteria for non-native speakers is to pass an assessment for their language skills.
