IMS have now released (registration required) the results of the QTI 2.1 implementation survey launched in January, looking in great detail into current implementations of the specification.

Twenty-one implementations are covered by the responses, representing a wide range of approaches to implementation, and the actual responses are available for download for those interested.  The responses support the notion of a core set of basic features implemented by all respondents, with broader parts of the specification being implemented on a more individual basis.

The results are feeding in to the development of profiles for QTI 2.1:

• Base QTI Profile, covering the features available in the most comprehensive implementations;
• CC-QTI, which updates the functionality covered by the QTI 1.2.1 profile within Common Cartridge 1.0 and which will be integrated into a later version of CC.

Profiling work, including the CETIS QTI working group activities, and subject-specific activities such as profiles for maths are also discussed.

This information will be very valuable for developers of tools and content, and it’s great to see IMS making it available to the community.
