The AP World History course requires students to engage with the dynamics of continuity and change across the historical periods that are included in the course. Students should be taught to analyze the processes and causes involved in these continuities and change. In order to do so, students and teachers should focus on FIVE overarching themes which serve throughout the course as unifying threads, helping students to put what is particular about each period or society into a larger framework. The themes also provide ways to make comparisons over time and facilitate cross-period questions. Each theme should receive approximately equal attention over the course of the year.
