High school students are increasingly likely to cheat their way to the top, according to the latest data from a nationwide survey about teenage ethics.

In 2006, more than six in 10 of about 34,000 high schoolers admitted to cheating on at least one exam in the past year. For 2008, data to be released in early November shows a slight increase, said Michael Josephson, founder of the Los Angeles-based Josephson Institute, which publishes the Report Card on the Ethics of American Youth.
