在分班考试中的糟糕表现使许多追求STEM（科学，技术，工程，数学）职业的美国学生无法直接进入大学微积分。相反，他们必须参加微积分预科课程，目的是更好地为以后的微积分课程做准备。在美国，两年制和四年制大学微积分预科课程的入学人数持续增长，这些课程的学生中有很多已经在高中学习过微积分预科的学生。我们研究学生在大学微积分的表现，使用回归不连续性，以估计采取大学预科微积分或没有的影响，在美国全国样本的5507名学生在132所院校。我们发现，学生谁采取大学预科微积分不赚取更高的微积分成绩。
Poor performance on placement exams keeps many US students who pursue a STEM (science, technology, engineering, mathematics) career from enrolling directly in college calculus. Instead, they must take a pre-calculus course that aims to better prepare them for later calculus coursework. In the USA, enrollment in pre-calculus courses in two- and four-year colleges continues to grow, and these courses are well-populated with students who already took pre-calculus in high school. We examine student performance in college calculus, using regression discontinuity to estimate the effects of taking college pre-calculus or not, in a national US sample of 5507 students at 132 institutions. We find that students who take college pre-calculus do not earn higher calculus grades.
