DUO Week was started in 2019 as a part of Mrs. Scott's Bible class project by three sophomores.  Mrs. Scott, an alumni of OCA and her Bible class wanted to "give back" to both OCA and their community, to spark school pride but also something that would make a lasting difference beyond themselves. They witnessed the incredible successes of Swine Week at Edmond Memorial and Balto, at Edmond North, and wanted to begin a similar week that would positively impact student culture at OCA. DUO Week, named "do unto others", OCA'S first philanthropy week, was born.

   DUO quickly worked and planned food nights, fundraisers, dress up days, get out of uniform days, and many more events for the recipient in 2019, Peppers Ranch. Peppers Ranch is a foster care community in Guthrie, OK that aims to provide a community for children and parents dealing with the foster care system. DUO Week's goal for the first year was $15,000, and through various efforts and the passionate generosity of the students and families at OCA, DUO Week raised over $25,000 dollars all for the children at Peppers Ranch. During our final assembly, we were informed that an anonymous donor had matched our amount taking the total up to a little over $50,000! We were so blown away by the impact our students had made considering the size of our school, and it being our first year. We quickly realized how God was going to work in this week both for OCA and in our community and our prayer is that it continues for years to come.
