TitleAssessment Authoring Open Service Interface Definitions

The Assessment OSID provides the means to create, access, and take assessments. An Assessment may represent a quiz, survey, or other evaluation that includes assessment Items. The OSID defines methods to describe the flow of control and the relationships among the objects. Assessment Items are extensible objects to capture various types of questions, such as a multiple choice or asset submission.

The Assessment service can br broken down into several distinct services:

  • Assessment Taking
  • Assessment and Item authoring
  • Accessing and managing banks of assessments and items

Each of these service areas are covered by different session and object interfaces. The object interfaces describe both the structure of the assessment and follow an assessment management workflow. They are:

  • Item : a question and answer pair
  • Response: a response to an Item question
  • Assessment : a set of Items
  • AssessmentPart: A grouped set of Items for fancier assessment sequencing
  • AssessmentOffering: An Assessment available for taking
  • AssessmentTaken: An AssessmentOffering that has been completed or in progress

The AssessmentSession is used to take an assessment and review the results. It captures various ways an assessment can be taken which may include time constraints, the ability to suspend and resume, availability of an answer key, or access to a score or other evaluation. Care should be taken to understand the various interoperability issues in using this interface.

An AssessmentSession may be created using an AssessmentOffered or AssessmentTaken Id. If instantiated with an AssessmentOffered Id, an AssessmentTaken is implicitly created and further references to its state should be performed using the AssessmentTaken Id.

An AssessmentSession is a mapping of an AssessmentOffered to an Agent at a point in time. The resulting AssessmentTaken is an identifier representing this relationship.

On the authoring side, Items map to Assessments. An Item may appear in more than one Assessment. Item banks may be used to catalog sets of Items and/or sets of Assessments.
