Concentration Declaration Day (CDD) is a new campus-wide tradition which began last year, aimed at celebrating an important milestone in the life of every Brown undergraduate--declaring a concentration and formally joining an academic community.
During Spring 2017, 42 concentrations hosted an event in April or May, either in a space in their department building or elsewhere on campus.
The CDD events ranged in format (casual drop-in or formal program with speakers). However you choose to run it, your event should focus on bringing together new concentrators, professors, and upperclassmen for one-on-one mixing a mingling, and giving new concentrators a chance to learn more about pathways for engagement within the concentration (research opportunities, seminars, etc.).
