Coding of alt text was needed to allow test developers to define when image was construct relevant. – Particularly important in mathematics to avoid interpreting graphs and charts. Lesson #1

[1] not construct-relevant and can be eliminated (e.g., it is only there for engagement purposes). [2] construct-relevant and can be represented using accompanying textual description. [3] construct-relevant and can be represented using accompanying textual description together with a tactile representation or physical manipulative. Addition of Alt Text Coding

Key, dashed line represents Roller Rink A, solid line represents Roller Rink B. The x- axis is labeled number of people. The y- axis is labeled cost in dollars. The dashed arrow starts at zero people, sixty dollars and points to a little less than sixteen people, midway between one hundred and one hundred ten dollars. The solid arrow starts at zero people, a little less than ten dollars and points to a little more than fourteen people, a little less than one hundred ten dollars. [2]

Key, dashed line represents Roller Rink A, solid line represents Roller Rink B. The x-axis is labeled number of people. The y-axis is labeled cost in dollars. [3] Note: Type 3 alt texts may be less lengthy than type 2 alt texts.
