In 2012 the state part of the "maturita" exam was split into two difficulty levels – students could choose between basic and advanced tests. This solution was found to be ineffective and was canceled the following year. The Czech Republic also has a separate examination system called "Národní srovnávací zkoušky" ("National Comparative Test"), owned and managed by the private company Scio, s.r.o. which provides tests for all subjects. Some Czech universities recognize the results of these tests and students can be accepted based on these results, however, they still have to succeed in the "maturita" exam. The examination itself is also divided between written and oral parts but not all subjects require both written and spoken input (for example math is formed by a written test only). Usually both the written and the oral part of the exam are set in late spring. The state part of the written exam is set to one day in which students in the whole country write identical tests, different tests are always issued on the day the exam takes place. The school (profile) part is always different and is based on requirements of the school which issues the test so it may be both written and spoken, but it can also be only one of the options. The oral part of the "maturita" exam takes part in a classroom in which a commissioner must be present. The oral exam is divided into two 15 minute parts (except Czech language and literature where the preparation time is 20 minutes), first a student draws a number of his question and then begins 15 minutes of preparation often called "potítko" ("sweat lodge") after the first 15 minutes he is called in to the 15 minute oral exam. The commission is composed of the class teacher, commissioner and either a principal or a representative principal. The student is examined by the examiner and an assessor. The examiner and the assessor usually agree on a grade which should be assigned to the student and if not the commission takes a vote for the grade. Students can graduate with a grade better than 5 (grades are 1–5, where 1 is the best). Exam duration, for both oral and written exams, as well as preparation time, can be longer for students with disabilities. If students fail in one subject, they have the option to repeat the subject, if they fail more than one subject, then they have to repeat the complete set of exams including the written part. All students have a maximum of three attempts to succeed in this exam, if they fail to succeed they end secondary school without the "maturita" and are unable to apply for college or university.
