Matrix Labeling

Matrix labeling items contain a grid in which elements are in rows, and the labels are column headers. Depending on the item, labels may be used more than once. Users select a label for each element by filling in answer bubbles at the intersections of rows and columns.

Matrix items are also accessible with audio and switches in the online format and can also be represented in paper-and-pencil and braille formats.
