ITS supports two types of item imports:
-
IAT-compatible imports: These imported items can be modified in our proprietary Item Authoring Tool (IAT).
-
Non-IAT-compatible imports: These imported items cannot be modified in IAT.
In general, items in QTI format are supported in IAT. Any other format is evaluated and determined during the initial phase of the process.
Most vendors’ stimuli are always compatible with IAT, but Educational Testing Service (ETS) stimuli are not.
