As increasing numbers of institutions are delivering high-stakes tests using Blackboard Learn, there is an increased desire on the part of course facilitators, instructors, and administrators to prevent students from cheating. High-stakes tests are often delivered to students in proctored lab environments to ensure that students can be identified—using an ID—and monitored while taking a test. However, if students can access the test from any location during the testing window, students could conspire to have someone else take the test on their behalf, compromising the security of the testing environment.
IP addresses identify specific computers and are a good method to enforce the location-restriction requirements described above. The first step is for your institution to create a range of IP addresses to correspond to one or more network segments that are used exclusively in the testing environments.
If your institution has not created a range of IP addresses for location restriction, you will not be able to restrict a test to a specific location. The option will not appear.
At times, you might need to allow a student or a group of students to take the test from somewhere outside of specified location (IP range). In this case, you can use the Test Availability Exceptions to exclude specified students or groups of students from the location restriction.
Students with this exception enabled will be able to take the test from any location, even if it is restricted for other students.
In a high-stakes testing situation you or the proctor can override a restriction that has been enforced by the system. On the Test Begin page, you can see the individual instances when users were prevented from accessing a test, along with an option to override this restriction to allow a user to continue taking the test.
These restrictions are logged by the system in the event that later review is required.
