“Fast Fast Sandwich Shop” – We’ll have that sandwich to you in an hour.

Airline Pilot on intercom – “Hello folks. Copilot and I need a bit of extra time to figure out the weight and balance of the airplane, our takeoff distance calculations and our navigational charts. We’ll be departing in 2 hours, so just hold tight and our wonderful cabin staff will be by with a drink cart in the meantime.”

Assembly Line Worker Bob – “Hey, I know we’re trying to produce 5,000 of these shiny new electric horseless carriages a week…..but I’m going to need another 20 minutes to figure out how to install this part I’m supposed to bolt on to every one as they come by down the line.”

I’m going to have to disagree with you Gasman. True depth of knowledge does mean a person can quickly and accurately perform a task. Never mind the business need for celerity in nearly every profession.

Level the playing field, by giving everyone enough time that the clock will not impact anyone’s final score.
Example: Write an exam expected to be finished by most students in 60 minutes, and schedule 2 hours. Those with 50% extra get three hours. Since everyone had vastly more time than necessary, neither the ‘neurotypical’, nor ‘disabled’ students are rushed. The exam will reflect what the student knows, and less so how fast any student can convey their knowledge.
