The oldest modern school in Nepal, the Durbar High School, and the oldest college, the Tri-Chandra College, are both in Kathmandu. The largest (according to number of students and colleges), the oldest and most distinguished university in Nepal the Tribhuvan University, located in Kirtipur. The second largest university, Kathmandu University (KU), is in Dhulikhel, Kavre on the outskirts of Kathmandu. It is the second oldest university in Nepal, established in November 1991. Not surprisingly the best schools and colleges of Nepal are located in Kathmandu and its adjoining cities. Every year thousands of students from all over Nepal arrive at Kathmandu to get admission in the various schools and colleges. One of the key concerns of educationists and concerned citizens is the massive outflux of students from Nepal to outside Nepal for studies. Every year thousands of students apply for ''No Objection Certificates'' for studying abroad. Consultancy firms specializing in preparing students to go abroad can be found in all prominent locations. The reason for such an outflux range from perceived low quality of education, political instability, fewer opportunities in the job market, opportunities for earning while learning abroad and better job prospects with an international degree.
