Ever wonder how a question ends up on a state test? Who writes, edits and approves it? There’s a nice peek behind the scenes of the $1.1 billion-dollar standardized test business, courtesy of stateline.org. CTB/McGraw-Hill, Educational Testing Service, Harcourt Assessment, Pearson Educational Measurement and Riverside Publishing create and score the tests, and together control about 90 percent of the state-testing business. Stateline’s Pauline Vu also examines the wide chasm in test quality and rigor from state to state. Good stuff.
