IMS Question & Test Interoperability Specification
The IMS Question & Test Interoperability (QTI) specification describes a data model for the representation of question (assessmentItem) and test (assessmentTest) data and their corresponding results reports. Therefore, the specification enables the exchange of this item, test and results data between authoring tools, item banks, test constructional tools, learning systems and assessment delivery systems. The data model is described abstractly, using [UML] to facilitate binding to a wide range of data-modelling tools and programming languages, however, for interchange between systems a binding is provided to the industry standard eXtensible Markup Language [XML] and use of this binding is strongly recommended. The IMS QTI specification has been designed to support both interoperability and innovation through the provision of well-defined extension points. These extension points can be used to wrap specialized or proprietary data in ways that allows it to be used alongside items that can be represented directly.
This QTI 2.1 v2 release completes the update from 1.x to 2.x by replacing those remaining parts of the QTI specification.
This v2.1 Public Draft Version 2 specification is a draft and liable to change before the completion of the Final specification. This draft addresses many of the issues raised with the v2.0 specification, resolution of other remaining issues will be included in the Final release.
Update:
Based on feedback from implementers and reviewers of the specification, the QTI project group has made bug fixes and updates to some of the examples, the specification documents, and the XML schema. The changes are summarized in this Addendum document and the updated examples and schema are also made available on the IMS website below.
The QTI project group encourages IMS GLC members and subscribers, as well as the general public to use this version of the specification to meet their assessment needs. The project group continues to work toward demonstrating interoperability based on actual implementations of the specification as a core requirement to move the specification to Final Release. To contribute to this process, share your implementations, or discuss profiling options, please contact Mark McKell, mmckell@imsglobal.org

IMS Question and Test Interoperability v2.0 Final Specification has three key objectives:
(1) To address relevant issues deferred from v1.0: a new information model has been defined with a new interaction model and a profile of XHTML to replace static material. Authors will now have more control over the behaviour and positioning of feedback and support for cloning using item templates has been added.
(2) To define a method for putting QTI into content packages: a new document has also been created dedicated to meta-data and usage-data (item statistics)
(3) To describe a method for using QTI with Learning Design, Simple Sequencing and the CMI data model
The key document to review is the Overview which describes the purpose of the other documents in the package. The Information Model document contains the detailed information, examples are provided and documented through the Implementation Guide. For those familiar with version 1.x the Migration Guide describes the differences, element by element. An experimental migration script has also been provided.
It should be noted that this specification is focusing on the Item. It is not updating Section and Assessment from v1.x, see the Overview document for more details.

IMS Question and Test Public Forum
The IMS Question & Test Interoperability Specification provides proposed standard XML language for describing questions and tests. The specification has been produced to allow the interoperability of content within assessment systems. This will be useful for publishers, certification authorities, teachers, trainers, publishers and creators of assessments, and the software vendors whose tools they use. Authoring tools, and publishers, may publish XML and this data can be imported into other authoring tools and delivery systems. An introduction to help you with your initial learning curve has been produced in the form of a white paper.
An Addendum to IMS QTI v1.2 was reviewed by the IMS Technical Board in March 2003. This addendum describes amendments that should be made by adopters of the IMS QTI Specification V1.2, thereby creating the IMS QTI V1.2.1 Specification. The differences between the V1.2 and the V1.2.1 specifications are limited to:
- Typographic corrections - corrections of spelling mistakes, wrong references, phraseology, etc.;
- Editorial additions - the provision of improved or new descriptions to clarify the specification;
- Functional corrections - changes to the functionality to correct mistakes and to clarify the intended capability of the specification.
