Many instructors use a syllabus quiz to ensure that students learn and understand the content of the syllabus. In this project, I move beyond this exercise's primary function and examine students' syllabus quiz scores to see if they can predict how well students perform in the course overall. Using data from 495 students enrolled in 18 sections of an Introduction to Sociology course, I find that students who do not earn a maximum score on the syllabus quiz are more likely to receive a lower final course grade and are less likely to pass the course than their top-scoring counterparts. These findings allow instructors to identify struggling students as early as the first week of the semester and design interventions that will match up with students' particular needs and strengths. Furthermore, this project demonstrates the pedagogical usefulness of the syllabus quiz beyond its initial purpose of testing students' knowledge of course policies and procedures.
