The "Bacalaureat" comprises 2 or 3 oral examinations and 4 or 5 written examinations, usually spanning the course of one and a half weeks in late June and September. It is a highly centralized, national exam. Usually the exam papers are taken to a centralized marking facility, sometimes even in another city, under police guard (for example in 2001 all the exams from Brașov were sent to Brăila for marking). The exam supervisors (always high school teachers or university professors) cannot teach in, or otherwise be related to, the high school they are sent to supervise.
