Andreas Schleicher recently blogged in response to my Ed Next article, “The International PISA Test,” but his response fails to deal with important issues I raised in my article: the quality of PISA’s analysis and the degree to which PISA’s reports ignore the limits of the data in support of conclusions that seem to have been determined in advance of the analysis. Another issue I raised is how PISA should fit into the U.S. system of testing and data collection.
