Question and Test Interoperability (QTI) refers to a set of standards and specifications designed to enable the exchange of assessment content and results between different systems and platforms. In simpler terms, QTI ensures that assessment items, tests, and related data can be shared and used across various assessment tools, learning management systems (LMS), and other educational platforms without compatibility issues. The main goal of QTI is to promote interoperability and compatibility among different assessment tools and systems, allowing educators, content creators, and administrators to create, share, and deliver assessments seamlessly. Overall, QTI plays a crucial role in enhancing the interoperability, efficiency, and effectiveness of assessment processes in education and training settings.
