Thinking of engineers here, and the clamoring for more engineering degrees, anyone teaching the discipline would as a rule be imparting knowledgeof no practical use.
The technology revolution increased the need for people with knowledgeof science, mathematics and engineering, but the number ofdegrees granted in these hard majors is roughly stagnant.
Critics ofthe idea also point out that, unlike America, Britain already has a reasonably standardised exam system, which is designed to instil the sort of specialist knowledge that British undergraduate degrees tend to require.
