Rule 31.10 Preservation of anonymity

When you take the Iowa bar exam, you get assigned a random number before the test starts. This number is used to identify your exam instead of your name. You'll use this same number throughout the entire testing and grading process.

The point of this system is to keep your identity hidden from the people grading the exams. Graders only see your number, not who you are. This helps make sure your test gets scored fairly, based only on how you answered the questions, without any chance of bias affecting the result.
