> The increase is driven by more young people getting diagnosed with conditions such as ADHD, anxiety, and depression, and by universities making the process of getting accommodations easier.
I think these disabilities are more complex than the broken hand and blindness examples for reasons I commented on elsewhere in this thread. In your example, a student with depression or clinical anxiety presumably only needs the same 10 minutes to write/type the answers as all the other students. Which means the extra time is added for them to "think about and solve problems." That seems fundamentally different to me than the broken hand example.
For real mental disabilities, extra time is actually necessary because a person's brain isn't able to work at the same rate as a healthy person under that situation.
I'm bipolar and have personal experience with this. My brain can lock up on me and I'll need five minutes or so to get it back. Depressive episodes can also affect my memory retrieval. Things come to me slower than they usually do.
I also can't keep track of time the way a healthy person does. I don't actually know how much time each problem takes, and sometimes I don't know how much time is left because can't remember when the test started. I can't read analog clocks; it takes me 10~20 seconds to read them. (1)
Extra time isn't giving me any advantage, it just gives me a chance.
1: I'm not exaggerating here. I've have dyslexia when it comes to numbers.
Here's what I need to do to figure out how much time is left:
- Dig through my brain to find what time it's started. This could remember something was being heard, something I saw, or recalling everything I know about the class.
- Hold onto that number and hope I don't flip the hour and minutes.
- Find a clock anywhere in the classroom and try to remember if it's accurate or not. While I'm doing this I also have to continuously tell the start time to myself.
- Find out the position of the hour hand.
- Tell myself the start time.
- Look at the dial, figure out the hour and try to hold on to it.
- Tell myself the start time.
- Tell myself the hour number.
- Tell myself the start time.
- Find out the position of the minute hand.
- Tell myself the start time.
- Hour forgotten, restart from the hour hand.
- Hour remembered, start time forgotten, restart from the top.
- Both remembered.
- Look at the dial, figure out minute and try to hold to it.
- Hour and start time need to be remembered.
- Combined hour and minute from analog clock.
- Figure out what order I should subtract them in.
- Remember everything
- Two math operations.
Now that I have the time and I don't remember what I needed it for.
- Realize I'm taking a test and try to estimate how much more time I need to complete it.
I could probably use a stopwatch or countdown, but that causes extreme anxiety as I watch the numbers change.
I don't have this kind of problem at my job because I'm not taking arbitrarily-timed tests that determine my worth to society. They don't, but that's what my brain tells me no matter how many times I try to correct it.
Let's take Alice and Bob, who are both in the same class.
Alice has clinical depression, but on this particular Tuesday, she is feeling ok. She knows the material well and works through the test answering all the questions. She is allowed 30 minutes of extra time, which is helpful as it allows her to work carefully and checking her work.
Bob doesn't have a disability, but he was just dumped by his long term girlfriend yesterday and as a result barely slept last night. Because of his acute depression (a natural emotion that happens to all people sometimes), Bob has trouble focusing during the exam and his mind regularly drifts to ruminate on his personal issues. He knows the material well, but just can't stay on the task at hand. He runs at out of time before even attempting all the problems.
Now, I can imagine two situations.
1. For this particular exam, there really isn't a need to evaluate whether the students can quickly recall and apply the material. In this situation, what reason is there to not also give Bob an extra 30 minutes, same as Alice?
2. For whatever reason, part of the evaluation criteria for this exam is that the test taker is able to quickly recall and apply the material. To achieve a high score, being able to recall all the material is insufficient, it must be done quickly. In this case, basically Alice and Bob took different tests that measured different things.
Put another way, if my brain works at a slower rate than the genius in my class, is it then unfair if my grades don't match theirs?
In general these seem like reasonable differences to consider when hiring someone for a job.

One Problem is, that we first have to clearly define the construct that we want to measure with the test. That is not often clear and often underdefined. When designing a test, we also need to be clear about what external influences contribute to noise / error and which are created by the actual measurement. There never is a test that does not have a margin of error.
A simple / simplified example: When we measure IQ, we want to determine cognitive processing speed. So we need to have fixed time for the test. But people also may read the questions faster or slower. This is just a typical range, so when you look at actual IQ tests, they will not give a score (just the most likely score) but also a margin of error, and test theorists will be very unhappy if you don't take this margin of error seriously. Now take someone who is legally blind. That person will be far out of the margin of error of others. The margins of errors account for typical inter-personal and intra-personal (bad day, girlfriend broke up) etc occurrences. But this doesn't work here. So we try to fix this, and account for the new source of error differently, e.g. by giving more time.
So it highly depends on what you want to measure. If you are doing a test in CS, do you want to measure how well the student understood the material and how fast they can apply it? Or do you want to measure how fast the student could do an actual real-live coding task? Depending on what your answer is, you need a very different measurement strategy and you need to handle sources of error differently.
When looking at grades people usually account for these margins of errors intuitively. We don't just rely on grades when hiring, but also conduct interviews etc so we can get a clearer picture.
