QTI Item

This is the XML structure, defined in QTI, that represents the question presented in an online test. The term 'Item' is used because the corresponding XML-instance contain more than just the information to present the question to the learner. It also includes: the response processing to determine if the answer is correct or not; the set of scores to be assigned to the learner and the rules for aggregating these scores; the alternative information to be rendered according to the accessibility needs and preferences of the learner; information to be presented as a hint.

QTI Package

This is the zip file that contains the QTI artifacts (QTI Test, QTI-Sections, etc.) and all of the related assets (images, video, etc.). A QTI Package is a formal profile of the 1EdTech Content Packaging specification. A QTI Package MUST contain the 'imsmanifest.xml' file which is the manifest of the set of files and the metadata for all of those files.

QTI Section

This is the structure used in the QTI specification to collect together QTI Items and child QTI Sections (this is the structure that enables the construction of complex hierarchical testing structures). QTI Sections are used to create different types of collections. A collection could consist of Items and Sections that have some pedagogic coherence. Alternatively they could have some relevance to the sequencing of the next Item to be prevented (for adaptive testing). The collection could also be for commercial reasons only.

QTI Test

This is the XML structure, defined in QTI, that represents the actual online test. In QTI 2.1 and later versions, a QTI Test MUST be composed of one or more QTI Test-Parts and each QTI Test-Part MUST contain at least one QTI Section. A QTI-Item MUST not be a direct child of a QTI Test or QTI Test-Part.

QTI Test-Part

This is the XML structure define in versions 2.1 and later of the QTI specifications. A QTI Test is composed of one or more QTI Test-Parts.  Each QTI Test-Part MUST contain at least one QTI Section. Typically, QTI Test-Parts are used for administrative purposes e.g. the full test may have several separately scheduled delivery sessions and so each session would be expressed as a QTI Test-Part.

Question & Test Interoperability (QTI)

Question and Test Interoperability (QTI)- the exchange of item, test and results data between authoring tools, item banks, test construction tools, learning systems and assessment delivery systems, including accessible assessments.

Example: We will be able to move our digital assessments to the new platform because both systems use the QTI standard. 

1EdTech has developed two tightly connected standards that the assessment community worldwide is using to improve learning. The first is QTI (Question and Test Interoperability) and the second is APIP® (Accessible Portable Item Protocol®). QTI enables the exchange of a wide range of rich questions and tests. QTI enables testing from formative quizzes to formal summative high stakes tests. And it allows all kinds of data to be transmitted between authoring tools, item banks, test construction tools, learning systems, and assessment delivery systems, and scoring administrative systems. 

test iconQTI provides an easier way to administer fully accessible digital assessments, both formative and summative, that provide actionable data in a more timely manner to teachers, students and parents to inform personalization of learning. For more information see 1EdTech's E-Assessment initiative and Question and Test Interoperability Project Group Activity. State and large district assessment leaders may be interested in participating in the State Assessment Leaders Innovation Leadership Network, for more information see the K-12 Innovation Leadership Networks.

There is also a full QTI Terms & Definitions document which defines QTI specific terminology.
