     A study involving 8 ,500 teenagers from all social backgrounds found that most of them are ignorant

when it comes to money. The findings ,  the first in a series of reports from NatWest that has started a

five-year research project into teenagers and money, are particularly worrying as this generation of young

people is likely to be burdened with greater debts than any before.

      University tuition fees (学费) are  currently  capped  at ￡3 , 000 annually, but this will be reviewed

next year and the govemment is under enormous pressure to raise the ceiling.

       In the research, the teenagers were presented with the terms of four different loans but 76 percent

failed to identify the cheapest. The young people also predicted that they would be eaming on average

￡31,000 by the age of 25, although the average salary for those aged 22 to 29 is just ￡17 ,815. The

teenagers expected to be in debt when they finished university or training, although half said that they

assumed the debts would be less than ￡10 , 000. Average debts for graduates are ￡12 ,363.

    Stephen Moir, head of community investment at the Royal Bank of Scotland Group which owns

NatWest, said, "The more exposed young people are to financial issues, and the younger they become

aware of them, the more likely they are to become responsible, forward-planning adults who manage

their finances confidently and effectively. "

      Ministers are deeply concemed about the financial pressures on teenagers and young people because

of student loans and rising housing costs. They have just introduced new lessons in how to manage

debts. Nikki Fairweather, aged 15 , from St Helens,  said that she had benefited from lessons on

personal finance, but admitted that she still had a lot to learn about money.
