These campuses have increased access to higher education among lower-income social groups. Also of note is the National Polytechnic University. Mexico City is also home to the National Center of the Arts, opened in 1994. This architecturally impressive complex houses facilities for students of the fine arts, music, film, and drama and contains a library and concert hall. In Mexico, many university campuses are highly political, and student groups often engage in ideological battles or become actively involved in national political issues.
Universities are often the sites of strikes by university employees.
While nearly all of the children in Mexico City between the ages of 7 and 13 attend elementary school, one-third never progressed beyond the 6th grade. There is a chronic shortage of school space, which is more acute at the secondary level. School space is in short supply partly because so many people have moved to Mexico City from rural areas. Mexico City has a wide range of museums and cultural attractions. The Templo Mayor museum contains artifacts of the city's early history.
