Are Your Products IMS Global Certified?
Ensuring that your educational technology tools are IMS Global certified is the best way to establish a plug-and-play ecosystem, allowing your systems and content to work together seamlessly, giving you more choice, and reducing your total cost of ownership.
As institutions and organizations look to procure QTI-based content or systems, it is important to include specific language in RFPs around IMS conformance certification. Assessment products should be certified to the current version and profile of QTI:
Example language could include a statement such as: “Vendor must provide evidence of a valid conformance certification, including a current registration number issued to the supplier and listed in the IMS certified product directory available at imscert.org
. Certification must be provided to the current version of QTI v2.2 State/Core Profile and when finalized, to the QTI v3 State/Core Profile.”
For additional information about conformance certification and language to include in an RFP, please see the QTI Primer
What’s New in QTI v3
- Improved presentation interoperability
- Web-friendly markup allows implementations to use standard web components in QTI structures
- Accessibility better supported by integrating APIP back into the base QTI specification and incorporating the relevant W3C specifications and accessibility best practices

What Else is Happening (Related Work)
LTI and QTI
The Learning Tools Interoperability®
) specification complements QTI by providing a way to integrate testing or an externally hosted assessment system with a student portal or learning platform, like an LMS, and then returning results or scores upon completion. LTI can also provide integration points for other parts of an assessment system such as item authoring, item previewing, test taker reviewing for scoring, etc.
Technology Enhanced Items
Portable Custom Interactions
(PCI): updates to the specification, which provides a standard way of authoring and delivering interactive or technology-enhanced question items.
Added Certification for QTI Results Reporting (coming soon)
Proctoring Service: establishes a standard way of proctoring exams through the use of LTI. (coming soon)

IMS Global has developed standards that the assessment community worldwide is using to improve learning. QTI is an open format that enables the interoperability of assessment items and tests. The latest version is 3.0, scheduled for public release in 2018.
QTI v3 derives from previous versions, namely version 2.2 and APIP version 1.1. APIP (Accessible Portable Item Protocol) is a set of accommodation extensions to use in conjunction with QTI 2.2. The APIP extensions have been streamlined and integrated into the QTI 3 standard.
A subset or profile of an older version of QTI, v1.2, is used in Common Cartridge®
, which is a format for importing and exporting content into/out of learning platforms. APIP v1.0 adds accessibility support to the QTI model to enable the electronic delivery of assessment to students with a variety of presentation needs and preferences.
All the versions of QTI and APIP are still supported by IMS Global.
QTI benefits suppliers and end users equally with cost savings of money, time, implementation and integration efforts all supporting the move from paper-based assessment to the future of digital assessments. These standards can be used for simple quizzes, formative assessments, or high-stakes/summative assessment.
QTI touches a variety of systems in a typical assessment eco-system enabling the exchange of question items, tests, and results data between authoring tools, item banks, test construction tools, learning environments, and assessment delivery systems, and scoring administrative systems.
An essential part of QTI is an exchange format for the organization of assessment results used for reporting and analysis, this QTI Result Reporting defines a way to capture and exchange individual student results of individual items or complete assessments across multiple contexts (class, school, district, state, etc.).
The assessment members in IMS constitute an active and vibrant community working together to enhance interoperability of test content and data to be better exchanged between assessment systems and different suppliers without loss of fidelity. Dedicated leaders from assessment suppliers and end-user organizations and institutions have formed the Assessment Product Steering Committee
(formerly called the EBA) to help set the assessment industry direction now and in the future.
The Assessment PSC is currently directing the efforts of the assessment activities in IMS to improve the IMS conformance certification process and to establish exact interoperability. It is also leading the development of the next version of the standard that brings together QTI and APIP into a new specification called QTI v3.
