     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.
