The Foreign Language Knowledge Level Determination Exam or YDS (Turkish: Yabancı Dil Bilgisi Seviye Tespit Sınavı) is a foreign language proficiency test administered by ÖSYM in Turkey in order to evaluate the foreign-language skills, especially of governmental employees.
The state pays extra money to public servants and employees of state agencies depending on their score on the test, and also uses this test to appoint employees to the positions located out of the country.
It is carried out in several cities throughout Turkey on the first Sundays of May and November.
The test consists of 80 multiple-choice questions to be finished within 180 minutes.
The fact that the test evaluates only the reading comprehension skills while ignoring the listening, speaking and writing skills has been harshly criticised.
