The problem with benchmarking is that it assumes all students are more or less equal. A measure that finds repeatable success for, say, 2/3s of the students will be model that will be emulated through the entire system to the detriment of the remaining 1/3 of students who do not learn under that environment. Students are not a commodity. What works well for one person does not necessarily work well for another. Without focusing on the individual, you are always going to leave a group needlessly behind.
