Nearly four dozen public and private schools in Indiana are offering Chinese language instruction for credit as part of an effort to make Mandarin Chinese the next world language.

Many of the programs are taught by Chinese educators through a collaboration between the College Board and Hanban, a government-funded organization affiliated with the Chinese Education Ministry.
