# Center Attendance While it is possible to retroactively add and modify center attendance records, the primary purpose of center attendance tracking is to capture real-time data. It allows you to have immediate access to up-to-date attendance information as participants check in and out of your center. It's important to note that only constituents with the persona of "Participant" will have the check-in button available. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
