@Kendodd If some kids take longer to do the same work, is it that they never finish?
Some finish but take longer (and what longer is varies individual to individual - hence differing amounts of extra time given) and some wouldn’t finish even with an unlimited amount of time.
So if the length of time to do an exam was doubled say, so it was more than enough time for everyone to answer all the questions are you saying some kids would still need extra time on top otherwise it's unfair?
Some DC need more than 100% extra time. See the example another poster mentioned of 200% extra time. This is because their additional needs means they need significantly longer. That can be for a multitude of reasons.
But also, if you give everyone else the opportunity to write for say 3 hours rather than the current 1hr30, then someone who has extra time at the moment is disadvantaged because their reasonable adjustment is removed. A pupil who doesn’t need extra time might still write for 3 hours so the pupil with extra time currently doesn’t have a reasonable adjustment compared to that.
Are you saying some kids will never finish and never answer all the questions?
Yes, some DC don’t answer all the questions.
