Massachusetts, like Connecticut, has long boasted top-performing public schools (“Massachusetts Is Like Connecticut, But Does a Better Job Educating the Poor,” Dec. 11, 2017). Students in both states scored at or near the top on national tests before the start of high-stakes testing. But then, as now, there have been huge differences in academic outcomes linked to race, income, language and disability. These gaps mirror the two states’ large (and growing) gaps in wealth and opportunity, as well as glaring inequities in school funding between rich and poor districts. … Rather than follow Massachusetts’ lead and impose more tests, Connecticut should implement an assessment system using projects and portfolios that promote and measure deeper, broader learning.
