Alexandria allows you to import and export item Lexile measurements, regardless if Alexandria's Lexile module has been licensed. Furthermore, even if you're not licensed to use Alexandria's Lexile module, you can apply an item Lexile measurement (0 – 2000) via the Lexile field in the Study Programs tab.

If a Lexile measurement has been applied to an item, and you are licensed to use the Alexandria Lexile module, it will be displayed in the Current Item section of the Circulation window.

As shown in the example below, the item has its Lexile measurement (860) displayed in Current Item pane of the Circulation window.
