HGSE professor Heather C. Hill cites a CEPR study in her Education Week op-ed on teacher practices and student test scores.

Many schools also instituted standardized “interim” assessments, claiming that this periodic, low-stakes testing could help teachers identify difficult content and struggling students before the state assessment, giving both teachers and students a chance to catch up. Over time, educational testing and data companies including the Achievement Network, NWEA, and McGraw-Hill’s Acuity began to sell interim assessments to schools and states, making such assessments (and their cousins, test-item banks that support formative assessment) a billion-dollar business.

Currently, a large number of teachers report they regularly get together to analyze student assessment results. In a 2016 survey by Harvard’s Center for Education Policy Research, 94 percent of a nationally representative sample of middle school math teachers reported that they analyzed student performance on tests in the prior year, and 15 percent said they spent over 40 hours that year engaged in this activity. Case-study research suggests that in many Title 1 schools, this activity is a cornerstone of teachers’ weekly or monthly collaborative time.
