The Josephson Institute, a Los Angeles-based ethics institute, surveyed 29,760 students at 100 high schools nationwide, both public and private. The survey found that 35% of boys and 26% of girls admitted stealing from a store within the past year and 64% have cheated on a test, which suggests that today' s young people are less honest than previous generations.

However, Josephson addressed that today's youth are no less honest than their predecessors. "The question is not whether things are worse, but whether they are bad enough to attract concern. This is not a time to complain but to take thoughtful, positive actions. "

Roberta Gerold, superintendent of the Middle Country School District and a leader of the campaign, said parents and school officials need to be more diligent – for example, emphasizing to students the distinctions between original and borrowed work. "Adults are not taking this very seriously," he said. "The schools are not doing even the most moderate thing."

Nijmie Dzurinko, executive director of the Philadelphia Student Union, said the findings were not at all reflective of the inner-city students she works with as an advocate for better curriculum and school funding. "A lot of people like to blame society's problems on young people, without recognizing that young people aren't making the decisions about what's happening in society. "

Riddile, who for four decades was a high school teacher, agreed that more pressure could lead to more cheating, yet he said, "I would take these students over other generations. I found them to be more responsive, more rewarding to work with. We have to create situations where it's easy for kids to do the right things. We need to create classrooms where learning takes on more importance than having the right answer. "
