Secondary teaching:
During the 1990s most state governments in the U.S. adopted requirements for the teaching of world history in public middle schools and high schools. This expansion in teaching world history led to a demand for textbooks, teaching materials, and professional development workshops for teachers.

In other countries teaching of world history has expanded, though usually not as a result of mandate by the state. Canada, Turkey, South Africa, Australia, and India are countries in which world history instruction in secondary schools is expanding. Private schools, especially English-language international schools, have given attention to the teaching of world history.

The AP World History course, sponsored by the College Board (New York) is a college-level course taken by high school students, with a single exam scored each year for students worldwide. (Students may receive college credit for the course.) Nearly 50,000 students took the exam in May 2004. This high-level course is important in building ties between high school and college levels of world history teaching.

Organizations of teachers of world history include the World History Association and, in the U.S., the National Council for the Social Studies.

College and university teaching:
Undergraduate surveys of world history have been taught in a growing number of universities since the 1970s, especially in the U.S. In the U.S. world history is taught as commonly as Western Civilization. Courses on world history are now taught in many countries (is this diffusion or independent invention?).

Materials for world history survey courses include textbooks, source books, synthetic and topical works, electronic resources, and print maps.

The discussion goes on: in some courses, "world history" is a succession of histories of separate regions, and in others "world history" is an overview of the interactions of regions and interactions among areas of human experience.

In addition to introductory surveys, a growing number of advanced undergraduate courses is appearing.

College and university teachers of world history tend to congregate at the World History Association.

Graduate teaching and Professional Development:
The preparation and development of teachers of world history is an issue of high priority in this era when world history teaching is expanding and promises to expand further. In some cases, governments have provided support for teacher preparation: the state of California has been exemplary in this regard. In other cases, professional associations and organizations have sponsored teacher workshops: for instance, the World History Association and the College Board. University programs at a few key institutions provide formal preparation for new teachers of world history.
