Brian Jacob study about test scores cited in Washington Post

Tags: jacob, test scores

A study by Brian A. Jacob on how student test scores are determined and why the process may be misleading to many people was the focus of a recent Washington Post article titled “Student test scores: How they are actually calculated and why you should care.”

Jacob’s study is titled “Student Test Scores: How the Sausage is Made and Why You Should Care.”

“Contrary to popular belief, modern cognitive assessments — including the new Common Core tests — produce test scores based on sophisticated statistical models rather than the simple percent of items a student answers correctly,” Jacob wrote. “While there are good reasons for this, it means that reported test scores depend on many decisions made by test designers, some of which have important implications for education policy.”
