QTI

QTI (Question and Test Interoperability) is the international standard that defines how questions and assessments are structured, packaged, and exchanged between digital learning platforms. Developed by 1EdTech (formerly IMS Global Learning Consortium) since 1999, it allows a question bank created in one authoring tool to be imported into any compatible LMS without losing structure, scoring logic, or feedback.

What does QTI stand for and where did it come from?

The acronym QTI stands for Question and Test Interoperability. The specification was launched by the IMS Global Learning Consortium in 1999 with a very specific goal: preventing assessment questions from becoming locked inside proprietary, incompatible formats.

Developing and validating a solid question bank takes time and expertise. Without a common standard, switching LMS platforms or authoring tools meant losing that investment or rebuilding it from scratch. QTI was created to solve exactly this problem: defining a neutral, XML-based language for representing questions, assessments, and results independently of the system that generates or consumes them.

The specification is currently maintained by 1EdTech, the organization that also develops other widely used standards in the sector such as LTI and xAPI.

What is QTI used for in e-learning?

In practice, QTI serves three main functions within a digital learning ecosystem:

• Assessment portability: export a test from an authoring tool and import it into a different LMS while preserving all question logic, answer options, correct responses, and scoring.
• Question bank reuse: share items across platforms, departments, or projects without having to rewrite them, reducing cost and time in recurring training cycles (onboarding, annual compliance, certifications).
• Results reporting: transmit learner response data between systems in a standardized way, enabling learning analytics and training audits.

For L&D teams, QTI is especially valuable when working with multiple technology vendors or when platform migration is a possibility — it ensures that the investment in assessment content doesn’t become obsolete every time a tool changes.

Question types supported by QTI

One of the standard’s key strengths is the wide range of question formats it can describe. QTI defines each question as an assessmentItem with its own interaction model. The main types are:

• Multiple choice (choice interaction): the most widely used type, supporting single or multiple correct answers.
• True/False: a simplified variant of multiple choice.
• Short answer (text entry interaction): the learner types a response in a text field.
• Ordering (order interaction): the learner reorders a list according to a given criterion.
• Matching (match interaction): connecting concepts from two columns.
• Drag and drop (graphic associate / gap match): placing elements on an image or completing gaps.
• Extended response (extended text interaction): essays or long-form answers that require manual or automated scoring.
• Advanced interactions (custom interactions): vendor-defined types for specific use cases, such as simulations or image-based exercises.

This variety makes QTI compatible with both summative assessments (at the end of a course) and formative assessments (throughout the learning process), including entry-level tests, reinforcement quizzes, and certification evaluations.

QTI vs SCORM: key differences

QTI and SCORM are complementary standards that are often confused because both operate within the e-learning ecosystem. The key difference lies in their focus: SCORM packages complete learning content (courses, interactive modules), while QTI focuses specifically on assessments and questions.

In practice, both standards can coexist: a SCORM package can include QTI-described assessments as an internal component. To explore how SCORM works in detail, check out our complete guide to what SCORM is.

QTI versions: how the standard has evolved

QTI has gone through three major generations, each expanding on the previous one:

• QTI 1.x (1999–2002): the first version, based on QML (Questions Markup Language) from QuestionMark. Functional for simple types like multiple choice. Versions 1.0 and 1.1 are officially deprecated.
• QTI 2.x (2005–present): a complete redesign of the data model, introducing the assessmentItem concept and a new interaction system. Version 2.1 added support for results and full assessments. Still the most widely implemented version in LMS platforms.
• QTI 3.0 (current version): published by 1EdTech, it adds native HTML5 compatibility, support for Computer Adaptive Testing (CAT), enhanced accessibility per W3C standards, and APIP (Accessible Portable Item Protocol) integration. Not all LMS platforms support it yet.

Version fragmentation is one of the real challenges of the standard: some LMS platforms only support QTI 1.2, others 2.1, and adoption of 3.0 is progressing gradually. Before migrating assessment content, it’s worth checking which version the target platform accepts.

QTI in corporate training

In enterprise training contexts, QTI has direct applications across several common L&D scenarios:

• Certifications and compliance: regulatory assessments (health & safety, data protection, banking, pharma) need to be maintained and updated year after year. QTI allows these evaluations to be reused and versioned without rebuilding the entire question bank.
• Onboarding programs: product knowledge or company culture tests can be created once and deployed on any compatible LMS, without being tied to a specific tool.
• LMS migrations: when an organization switches from one LMS to another, QTI makes it easier to export existing assessments without data loss, reducing the cost and risk of the transition.
• Vendor collaboration: when content is developed by an external provider but deployed on an internal LMS, QTI acts as a neutral delivery format, independent of the authoring tool used.

According to 1EdTech’s State of Learning Technology 2024 report, interoperability remains one of the top three LMS selection criteria in mid-size and large organizations. QTI, alongside LTI and xAPI, is part of the core set of standards that make this interoperability possible in the assessment domain.

Limitations and practical considerations

While QTI is the reference standard for assessment interoperability, its adoption across the market is not uniform. There are three things L&D leaders should keep in mind:

• Inconsistent LMS support: not all learning management systems implement QTI in the same way. Some only accept subsets of the standard (for example, multiple choice only) or specific versions (QTI 1.2 vs. QTI 2.1).
• Proprietary extensions: some vendors implement their own extensions on top of QTI, which can cause issues when importing into another system. IMS conformance certification is the best guarantee of real-world compatibility.
• Implementation complexity: the standard, especially in version 2.x, is technically complex. Piotrowski (2011, IGI Global) identified ambiguities in the specification that complicate consistent implementation across vendors.

In practice, if portability is your goal, the safest approach is to verify with your target LMS vendor which QTI version it supports and which question types it can import correctly — before designing your item bank.

How QTI relates to other e-learning standards

QTI doesn’t operate in isolation: it fits within a broader ecosystem of educational technology specifications. The most relevant ones in relation to QTI are:

• SCORM: the reference standard for complete learning content, which can incorporate QTI assessments as a component.
• xAPI (Tin Can): a learning experience tracking protocol that complements QTI by transmitting assessment results to a Learning Record Store (LRS) with greater granularity.
• LTI (Learning Tools Interoperability): allows external tools to integrate into an LMS. Can be used to launch QTI assessments from third-party platforms.
• IMS Content Packaging: a content packaging specification into which QTI can be embedded as an additional content type within a learning object.

If you work with an authoring tool and want your content — including assessments — to be compatible with as many LMS platforms as possible, understanding how these standards interact will help you make better instructional design decisions.
