You may limit the number of times a user is permitted to access your assessment in a number of ways. In a typical testing environment, the following limits are usually set to 1.

Request Limit - this limits the number of times a participant may log into or see an assessment. You may optionally specify that this limit only be enforced on a daily basis. That is, for a tutorial you might want your participants to access the tutorial twice a day. This limit requires you to specify a list of authorized participants for your assessment. You may at any time grant an exception to this limit.

Submission Limit - this limits the number of times a participant may submit responses to an assessment. You may optionally specify that this limit only be enforced on a daily basis. That is, for a tutorial you might want your participants to complete the tutorial twice a day. This limit requires you to specify a list of authorized participants for your assessment. You may at any time grant an exception to this limit.

prevent multiple submissions - since Test Pilot can inform users of the correct answers to questions, you may want to prevent users from seeing that information, clicking back in their browser and making changes to their responses. This could happen in cases where you permit multiple submissions. Checking this box will cause Test Pilot to ignore multiple submissions of the same assessment. This particular option does not require the existence of an authorized participant list.
