Education Standards

I’m a new student here and feel as I’m speaking out of turn. I’ve completed some fairly technical tests. In the essay writing section, my issue is, are we really only holding ourselves to the communication skills of a 4th grader. That’s all the test requires.
Now I’m not saying we should be college professors, but shouldn’t the essays
require at least high school level writing skills as do most states require a high school diploma to be certified.
Not putting anyone down, just a question.
