When implementing schoolwide PBIS in secondary schools, creating effective acknowledgment systems for expected student behavior can be challenging. To overcome this challenge, it is helpful to understand acknowledgement preferences from the student point of view. In this study, we surveyed students in three middle, two traditional, and two alternative high schools to understand their preferences. When presented a list of options, most students endorsed positive notes sent home, free time/fun activity, and snacks. Few students endorsed eating lunch with an adult, wearing something fun, earning a special job in class, and public recognition. School leaders are encouraged to engage students directly by asking them their acknowledgement preferences and adjusting their practices to fit the preferences of their students.
