Research by Brian Jacob appears in a Wall Street Journal article titled "Students' Regents Test Scores Bulge at 65." Jacob's research—commissioned by the Wall Street Journal—statistically analyzed data from the New York State Regents Exam, a series of five tests students must pass in order to graduate from high school. The goal of Jacob's analysis, with co-investigators Thomas S. Dee and Justin McCrary, was to determine if teachers were "scrubbing" the test scores of students close to failing—bumping up their scores to a passing grade of 65 percent.
The paper, "Manipulation in the Grading of New York's Regents Examinations," can be downloaded from Jacob's website.
