What Do We Actually Want to Measure?
Start by identifying the construct being measured: reading, or understanding the idea? Math, or writing? If reading speed isn't the goal, extra time or an audio-read version may be appropriate for some students.
Avoid changing a core element of the task without documentation, since that can change the meaning of the result and make it harder to compare progress.
What Are the Practical Options for Adapting an Assessment?
You can adjust the exam's time, location, question format, or response method, and use large print, a screen reader, or short breaks. The accommodation should be familiar to the student before assessment day.
Use multiple assessments over the term: observation, a work sample, a performance task, and a short test. A single source doesn't always give a sufficient picture of learning.
How Do You Document the Quality of an Adapted Assessment?
Record the goal, the accommodation, why it was used, and the result. Check whether the adjustment removed the barrier without providing help with the content being measured.
Discuss the results with the student, family, and team, and adjust the plan if it turns out the assessment method itself is still preventing learning from being shown.
