At Yale University, enrollment in basic Chinese in 2005 grew rapidly, and for the first time professors can remember, large numbers of freshmen were arriving with enough knowledge of the Chinese language to start in second- or third-year Chinese language class, rather than basic Chinese.

The American interest in China is not just at the university level. In the 2006 school year, high-school students will be offered an Advanced Placement test, which is one of the national exams American students take for university admission, in Chinese. This is the first time Chinese is offered in the Advanced Placement test, which is usually limited to the most important subjects that high school students take.

What is surprising is that earlier last year, an organization that tracks university students surveyed high schools throughout America, asking if they planned to offer the language courses that prepare students for the language Advanced Placement test. They expected that only a hundred high schools, mostly in California, New York, and a few other places with large immigrant populations, would show interest in each of the new language programs. Although that was true for the courses in Italian, Russian and Japanese, it was not true for the Chinese language course. There were thousands of American high schools that indicated that they planned to build their Chinese programs to levels where students could take the Advanced Placement exam for Chinese language. The demand for courses in Chinese is rising so rapidly that it is rapidly overtaking all other foreign languages except Spanish.
