Lake Wobegon has nothing on the UW-Madison School of Education. All of the children in Garrison Keillor’s fictional Minnesota town are “above average.” Well, in the School of Education they’re all A students.
The 1,400 or so kids in the teacher-training department soared to a dizzying 3.91 grade point average on a four-point scale in the spring 2009 semester.
This was par for the course, so to speak. The eight departments in Education (see below) had an aggregate 3.69 grade point average, next to Pharmacy the highest among the UW’s schools. Scrolling through the Registrar’s online grade records is a discombobulating experience, if you hold to an old-school belief that average kids get C’s and only the really high performers score A’s.
Much like a modern-day middle school honors assembly, everybody’s a winner at the UW School of Education. In its Department of Curriculum and Instruction (that’s the teacher-training program), 96% of the undergraduates who received letter grades collected A’s and a handful of A/B’s. No fluke, another survey taken 12 years ago found almost exactly the same percentage.
A host of questions are prompted by the appearance of such brilliance. Can all these apprentice teachers really be that smart? Is there no difference in their abilities? Why do the grades of education majors far outstrip the grades of students in the physical sciences and mathematics? (Take a look at the chart below.)

The UW-Madison School of Education has no small amount of influence on the Madison School District.
