Broadcast Security Options - expiration date, time limit, maximum downloads
When an Audio Exam is created it will not expire on the teacher’s iPad, and it is secure. However, each time an exam is broadcasted it is “handed out” to a student or students by giving them the test code. To enable teachers to protect exams that have been broadcasted, each broadcast has a number of security options - expiration date, time limit, maximum downloads, and require name. By default, the Expiration Date (& time) on an exam is 24 hours from the time it is broadcasted and the "Time Limit" is 60 minutes from the time it is downloaded. This expiration date can be increased to cover the period when the test will be used by students.
Removing limitations on when and how the exam can be downloaded decreases the security of the exam. The default settings are moderately narrow to protect the academic integrity of the exam. Teachers can rebroadcast an exam as many times as needed and receiving a new test code for each broadcast. When higher security is needed, narrower time limits are used. Broader time limits are used when security is not as critical.
