Online, adaptive testing for Common Core

Let's see. These "tests" are meant to be used to determine the success or failure of students, effectiveness (of lack thereof) of teachers, rank and sort schools, decide school closures, and who knows what else they'll pile on. But, it didn't work properly. How are the kids supposed to maintain composure, keep from panicking, and do their best when the damned thing glitches and hiccups during testing? Can you imagine remaining calm during a medical diagnostic test gone awry? How valid would the findings be? And better, I want to know why we shouldn't go back to pencil and paper. At least there is a minimum of shit to hit the fan that way.
