Thetas are involved with CASA in many ways. Each year, Theta college and alumnae chapters host fundraisers to support their local CASA chapters. These events raise tens of thousands of dollars annually to support CASA's work. More importantly, Theta members provide personal support by volunteering their time in local CASA offices, making toys or items for CASA children, hostessing events for CASA children, or assisting with CASA fundraisers. Many Thetas complete the training to become CASA volunteers themselves.

Kappa Alpha Theta has aimed to exercise the widest influence for good and to show love to others. These aspirations have given Kappa Alpha Theta a distinguished history of community service and philanthropic involvement. Since 1989, the focus of Kappa Alpha Theta's philanthropic work has been CASA, the Court Appointed Special Advocates program (also known around the country as Guardian Ad Litem and Pro Kids).
