Examinations are set and externally marked by OCR/Ciso Systems (via omputer). Examinations take the form of omputerised multiple hoie objetive tests. 110 OCR Level 3 Certifiate/Diploma for IT Professionals

5 The examination is administered on a omputer at an authorised Ciso network aademy. In an easy to use format, the omputerised tests look very muh like other multiple hoie tests. The 90-minute examination onsists of 60 objetive test items. The test item format used in the omputerised test is: Multiple hoie: The examinee selets one option that best answers the question. To ahieve this unit within the OCR Level 3 Certifiate/Diploma for IT Professionals all andidates must ahieve a Final Exam sore of 70% or more, and entres should not submit gradebooks for andidates who have failed to ahieve this. The gradebook must display the orret andidate name, the name of the Ciso qualifiation and the required Final Exam sore. OCR Level 3 Certifiate/Diploma for IT Professionals 111
