The scope and depth exam speak to the fact that educational priorities have changed since the 1930s. Science and math, for example, are emphasized much more today. Other subjects are emphasized less. Does this constitute a regression?

Many of the questions reek of rote learning and propaganda. Being able to give the "official" reasons for America's "wonderful growth in its 155 years of existence is not necessarily a sign of intelligence or worldly knowledge.

Are there things that 1930s education did well? Undoubtedly. But this test is poor evidence either way.
