This paper considers an unavoidable feature of the school environment, class rank. What are the long run effects of a student's ordinal rank in elementary school? This research shows that students with a higher third grade academic rank, conditional on achievement and classroom effects, have higher subsequent test scores, are more likely to take AP classes, to graduate from high school, enroll in college, graduate from college, and ultimately have higher earnings 19 years later. This research studied the classroom rank of 3rd grade public school students in Texas for students between 1995 and 2008. Classroom rank is constructed using standardized test scores for students who took the exams in English. Academic achievement and rank are highly correlated.
