The Question & Test Interoperability (QTI®) specification is a technical standard developed by **1EdTech** for the digital interchange of assessment content, such as items and tests, as well as assessment usage data and results reporting.
Key Features of QTI:
– Interoperability: QTI enables the exchange of item and test content and results data between various systems, including authoring tools, item banks, test construction tools, learning platforms, assessment delivery systems, and scoring/analytics engines.
– Presentation Consistency: It ensures a standardized assessment content presentation across different applications, providing a consistent user experience.
– Accessibility: QTI complies with federal accessibility requirements, including Section 508 and WCAG 2.1 AA guidelines, ensuring that assessments are accessible to all users.
– Flexibility: Institutions and suppliers can author, import, export, and present assessments flexibly, maintaining ownership of their content when switching between applications.
– Rich Content: QTI supports rich assessment content, including context (metadata), response details, scoring logic, and usage data (such as item difficulty and other statistics).
Versions:
– QTI v3.0: The latest version, which builds on earlier versions and includes improved presentation interoperability, web-friendly markup, and better integration and accommodation solutions.
QTI is primarily in XML format, allowing for structured and flexible markup of assessment content. This makes it a powerful tool for creating and managing digital assessments in a standardized and interoperable manner.
