  1. Graphics

Graphics such as pictures, charts, and diagrams can be used to help students understand item text by depicting information in an item or a set of items. Graphics can be very effective in supporting text, illustrating mathematical concepts in the text, and increasing item access with minimal cost. If used improperly, however, graphics can add substantial confusion and distract test takers from what items are asking students to do. When using graphics,

  • use visuals that mirror and parallel the wording and expectations of the text.

  • illustrate only necessary information in the graphics.

  • represent each important part of the item in the visual images.

Example 25 is an item that illustrates only necessary information and parallels the expectations of the text.
