I agree with that, but would you say that the "trend", if there is one, is towards providing that through AI, or more humans?

If I recall, they had computers grade the GMAT essays for at least 10 years, but they had to have a human in the loop because that is the ultimate measure for whether a computer is "correct" in terms of grading an essay.

The trend is towards neither, I'd say. The biggest trend has been towards online automatically graded multiple choice & short answer questions that aren't really open ended.

The automated essay grading stuff typically looks at writing style more than content, but it's true that it's a problem that tons of people have worked on and there's been some cool progress there as well. We're not really working on bringing AI to essay grading ourselves though.
