Education policies must stand the test of analysis and comparison to achieve the best results and ultimately help with governance and public service. Universities today have to raise money to supplement insufficient funding. They have to emphasize both teaching and research, ensure quality, update curricula, implement academic exchanges, cope with rising student requests for face-to-face dialogues, provide scholarships and subsidies as well as employment assistance, promote innovation and entrepreneurship, and deal with populism, abuse, politicians, demonstrations, and so forth. AT&T achieved efficiency through applying statistical control, which developed into today's concept of total quality management. Professional accreditation is part of the evaluation of university programs. In addition to professional accreditations, there are rankings based on evaluation results. Evaluation of teaching performance in universities started in the US at the end of the 1960s. Teaching and research are the primary mission of the university.
