In the two years Madison has collected and shared value-added numbers, it has seen some patterns emerging in elementary school math learning. But when compared with other districts, such as Milwaukee, Kiefer says there's much less variation in the value- added scores of schools within the Madison district.
"You don't see the variation because we do a fairly good job at making sure all staff has the same professional development," he says.
Proponents of the value-added approach agree the data would be more useful if the Wisconsin Department of Public Instruction were to establish a statewide value-added system. DPI is instead developing an assessment system to look at school-wide trends and improve instruction for individual students.

But some question whether value-added data truly benefits all students, or is geared toward closing the gap between high- and low-performing students.
"Will the MMSD use new assessments...of students' progress to match instruction levels with demonstrated learning levels?" asks Lorie Raihala, a Madison parent who is part of a group seeking better programming for high-achieving ninth- and 10th-graders at West High School. "So far the district has not done this."
Others are leery of adding another measurement tool. David Wasserman, a teacher at Sennett Middle School and part of a planning group pushing to open Badger Rock Middle School, a green charter (see sidebar), made national news a few years ago when he refused to administer a mandatory statewide test. He still feels that a broad, student-centered evaluation model that takes multiple assessments into account gives the best picture.
"Assessment," he says, "shouldn't drive learning."
