"I do carpet installation and the first question I ask prospective help is "Can you read a tape measure?""
(The following is not intended to blame the student. The school did it.)
Back in the '80s, I had a high school graduate referred to me for job placement assistance. He'd been trained for two years at the tech center to do siding work, etc.
He could read a tape measure, but nobody would keep him on a job. He measured everything in sixteenths. "That's 53 inches and one, two, three, four, five, six, seven, eight, nine, ten, eleven sixteenths."
He couldn't reduce fractions and couldn't run a saw either.
But the school said he was prepared. (I was a state employee fwiw.)
