Several higher education groups and policy organizations are opposing the planned sale of Walden University, an online institution, from one for-profit college operator to another, they wrote in a letter to U.S. Education Secretary Miguel Cardona this week. The organizations called out Adtalem Global Education, which plans to acquire Walden, for its record of running an online university accused of engaging in misleading and aggressive recruiting practices. They also expressed concerns with Adtalem seeking "unrestricted ability" to expand programs and enrollment levels at Walden and are asking the department to instead put caps on both.
