WEST LAFAYETTE, Ind. (WOWO): Gallup has partnered with Purdue University for the largest representative study of college graduates in U.S. history. The Index will measure the most important outcomes of higher education, which Gallup says are “great careers and lives that matter,” and it will give education leaders insights for meaningful performance improvements. The initiative aims to create a national movement toward a new set of measures for higher education. Purdue will be the first university to contract for a simultaneous sampling of its graduates, to find out how they are faring in life and at work.
