Overriding can be done at both the analysis level and/or the LIC level.

To override tags:

Select the Statistics Tag icon
The Statistics Tag modal displays
- The Criterion Score Analysis is the first row displayed followed by LIC(s) listed in alphabetical order
Clicking on the Analysis row will display any tag selections that are inherited from the tags selected in the analysis template (all checkboxes will be disabled)

NOTE: If items are shared between LICs, and more than one LIC has tag overrides applied, the last LIC in the list will take precedence and the selected tags for that LIC will be applied to the item.

Select Apply after all tag selections have been made
If Cancel is selected no selections will be saved

3. Use Equate Item Statistics (optional)

Within an Item Analysis - Classical template, you're able to use a reference univariate frequency distribution (CUSFDS) to be used for equating item statistics purposes.

This analysis should only be performed using a scaled score frequency distribution
If Compare Deltas has been selected in the analysis template, this option will not be displayed for the test in Test Settings.

Select the checkbox next to 'Use Equate Item Statistics' to open a modal where you'll select a request to use.

Enter a valid request number and select Search
A list of request/analysis sequence numbers will display including the following context information:
- Request ID is the combination of program, request number, and analysis sequence number

LIC - a single-select drop down that lists all LICs configured for the selected test

- Once a row is added, there is a Delete icon enabled next to each row.
- At least one row needs to be included to be able to save successfully
