“…For example, economists routinely use achievement test scores as indicators of student learning, understanding that the scores are not perfect as indicators of learning but are the best quantitative measures available for statistical analyses (e.g., Rivkin, Hanushek, and Kain, 2005). Achievement test scores, in particular, have been found to be correlated with other outcomes, such as high school completion, college enrollment and completion, job status, future earnings, and other measures of success (e.g., Carnevale, Fry, and Lowell, 2001;Chiswick, Lee, and Miller, 2002;Jencks et al, 1979;McIntosh and Vignoles, 2001;Sewell, Hauser, and Featherman, 1976;Tyler, Murnane, and Willett, 2000).…”
