Don't be deceived.

I actually think that Kohn's argument is pretty good. He talks about how the opposing side just relies on SAT scores, and elite university student grades.  "First, it is difficult to argue that a standardized test taken in high school and grades for college course work are measuring the same thing. "this quote says that the opposing people don't consider whether what high school they went to where the curriculum they were taught helped them achieve the A's in college and get better SAT scores, The opposing side doesn't take notice into whom has took the SAT's, there are bad test takers, people that don't study, and people who don't even take the SAT's at all, so there are not even counting the whole population. It sounds like Kohn even noticed that there argument is not even a argument  they are begging the question. Their claim is "Grades are inflated because teachers are too lenient in grading" basically, this is begging the question because every teacher has a different curriculum, syllabus, grading system and teacher style so with their argument they are not really going to get far. The author mentions that it also depends on the type of test their taking, because when you take multiple choice questions, it doesn't really get into depth of what you should know it just covers the surface of the topic. The author then explains the reasons for grade inflation such as getting into good graduate schools (where experience matters more than grades) and special awards look good on resumes. His argument was successful because he poked holes through his opposing argument, stated why the topic was relevant and gave some support of from his own research.
