The most common testing accommodation you may see on student plans is either 50% or 100% extra time.
If a professor decides to provide the entire class with additional time to complete a test that is believed to take less time, a student with a 50% or 100% extra time accommodation should still be provided with their accommodated time on top of the time provided to the rest of the class. For example, if the professor creates a test that they believe should take the class 1 hour, but wants to provide all students with 2 hours to complete the test, a student with an accommodation for extra time should still receive their accommodated time in addition to the 2 hours provided to the rest of the class. A student with a 50% extra time accommodation should receive 3 hours to complete this test and a student with a 100% extra time accommodation should receive 4 hours.*
