Blackboard Learn’s Caliper Analytics stream has two event types dedicated to assessments:

  • AssessmentEvent
  • AssessmentItemEvent

These events work hand-in-hand. An AssessmentEvent is fired whenever a student starts or submits a test, and the AssessmentItemEvent is fired whenever a student starts or submits a question on an assessment.

Here is some of the key data that is associated with these events:

AssessmentEvent

group.courseNumber - the course batch_uid (i.e. the ID sent in by LIS or Data Integration)

object.@id - …/assessments/id - the primary key for the assessment ID

action - …/action#Started or …/action#Completed

AssessmentItemEvent

group.courseNumber - the course batch_uid (i.e. the ID sent in by LIS or Data Integration)

object.@id - …/questions/id - the primary key for the question ID

object.ispartOf.@id …/assessments/id - the primary key for the assessment this questions is a part of

action - …/action#Started or …/action#Completed

Sample Workflow

Here is a sample of what a workflow might look like:

  1. Start a Test
  2. Start a Question
  3. Submit a Question
  4. Submit a Test
