From Milwaukee Public Schools, 2006-7 School Report Card (click to see full report card). When value added is implemented in MMSD, we can expect similar reporting. Note that the gray areas are “error bands,” indicating 95% confidence intervals.
From an email sent by a DPI employee to Peter Sobol of the Monona Grove Board of Education.
… The WKCE is a large-scale assessment designed to provide a snapshot of how well a district or school is doing at helping all students reach proficiency on state standards, with a focus on school and district-level accountability. A large-scale, summative assessment such as the WKCE is not designed to provide diagnostic information about individual students. Those assessments are best done at the local level, where immediate results can be obtained. Schools should not rely on only WKCE data to gauge progress of individual students or to determine effectiveness of programs or curriculum.
From the WCER Value Added Research Center (contracted with MMSD and MPS).
Benefits of Value-Added Methods
Value-added methods “get the story right” by correcting for errors in the test scales, identifying and adjusting for bias in the administration of the test, in student participation, or in classroom treatments. In addition, one of the overriding goals of the work is to be transparent and fair. It is in everyone’s interest for schools to be as productive as possible for all students.
All teachers should be able to deeply understand and discuss the impact of changes in practice and curriculum for themselves and their students. Leaders should be able to make resource allocation decisions (money, staffing, etc.) informed by the best available data. Value-added methods can both showcase high levels of achievement as well as reward those who have mastered the art of improvement.
The MMSD value added analysis will rely on WKCE tests.
Anyone see a problem?
I’ve been working on a long post about the basics, benefits and limits of Value Added Analysis. Still a lot of work to do on that. Till then, here are two recent stories from Education Week (registration may be required).
