According to the American Psychological Association (APA):
"Because the Publication Manual provides guidelines for writers submitting manuscripts to scholarly journals, it is silent on the topic of tables of contents...Style preferences for undergraduate writing can vary by discipline, university, and instructor. Instructors should provide their preferred formatting guidelines if they require tables of contents; if guidelines are not included with the assignment or syllabus, students can request them."
Students in the MSA program can find a sample Table of Contents in "Part 1 The Student Guide to the MSA Capstone Project" (July 2016).
If you are uncertain how your Table of Contents should be formatted, please check with your instructor for guidance.
