But the Ankara Prosecutor's Office did seek permission to investigate Ali Demir, head of the Student Selection and Placement Center, which runs the Transition to Higher Education Examination, the newspaper Today's Zaman reported.
Soon after the test was administered March 27, claims of cheating arose.
The center was accused of inserting a code into the multiple-choice answers. In booklets made public after the exam, it appeared that by rearranging numerical answer choices in ascending order, someone who knew the code could find the correct answer without reading the question.
