This chapter focuses on children’s experiences taking part in the standardized testing that was designed to measure the effects of the interventions enacted by teachers and educators with the children in the Enhancing Children’s Attention (ECA) project. Critics of standardized testing usually describe it as an objectifying practice, where the children have little or no chances of affecting the practices. This critique is often presented in sweeping terms, as something problematic in general, thereby leaving the locality and the specificity of particular test situations out of the story. By analyzing video recordings of children and adults during the pre- and posttesting situations in the ECA project, this chapter investigates the concrete, local, material, relational, and other specific circumstances of what it might mean, as a young child, to take part in standardized testing.
