Properties
The Properties section applies to all item types. 
NOTE: To see all of the available properties, ensure that the white and green triangle icon in the upper right corner of the section is pointing upwards.
Properties allow for the classification of items (Item category, Linguistic Scale level, Task), their configuration (Allotted time to answer) and their status (Approved Item or to Recalibrate).
A user can only modify properties within the limits set by their assigned role. Some properties (Item category, Linguistic Scale level, Task, Indicator, Allotted time to answer) are entered by the editor when adding items, as specified in the original documentation provided by content specialists. Difficulty levels, Discrimination and Chance are added either manually by an approver from the data provided by an adaptive test specialist following the statistical analysis of a representative sample of respondents or automatically when the TPLS administrator proceeds to calibration. The Approved item and to Recalibrate properties can only be used by an approver.

There are ten possible properties:
- Item category: Select the item's category from the list. The categories are determined in the administration module and cannot be modified or deleted.
- Linguistic scale: Select the item's proficiency level on the linguistic scale.
- Indicator: Enter the specific indicator of the proficiency level.
- Allotted time to answer: If the question requires a time limit with a counter to be displayed during the test, select the Yes option and enter a value (in seconds) in the field. This field remains inactive until the Yes option is selected.
NOTE: If the item includes sound or video, the timer starts when the media finishes playing. The Allotted time to answer should not be used to increase the level of difficulty of an item. It only serves to encourage respondents to answer as quickly as possible, without searching for the answer on the Internet or asking the opinion of others. The Allotted time to answer should be long enough for a respondent to read and answer the question, even if the respondent’s reading skills aren’t advanced. - Difficulty, Discrimination and Chance: Only authorized persons (approval role) can add or change the value of these fields according to the specifications of an adaptive test specialist. These values can also be added automatically by the TPLS calibration process. They are primarily used for the adaptive algorithm of the test. Only approved and calibrated items (with at least one value in the Difficulty field) are used by the test in Adaptive mode.
- Recalibrate: Only authorized persons (approval role) can recalibrate items. Select the Yes option to recalibrate the item. Only approved items can be recalibrated. The item will then be recalibrated during the next calibration initiated in the administration module.
- Approved item: Only authorized persons (approval role) can approve items. Select the Yes option to approve the item. Only approved items are used in the test, whether in Adaptive or Non-adaptive mode.
- Task: n/a
