In this interview Jessica Bimba, Virginia Lighe, Sudacious Varney, and Veekie Wilson explain the process used to remove ghost workers from Liberia's teacher payroll, review qualifications, and test functional literacy in English and math. This exercise began in 2015 with a pilot project and concluded in 2017. The interview briefly discusses the creation of a project implementation unit and then outlines the steps taken to explain the process, identify "ghosts," check qualifications, administer the test, and issue a biometric id. The participants explain the rationale behind several important decisions. They also talk about some of the challenges they faced and how they addressed them.
