     When we hear the words "college student", we usually think of a young person between 18 and 22 years

old. But in the USA today, a college student often is much older. In fact, educators say in the next few years

colleges and universities may have more older part-time students than traditional full-time younger students.

     Educators report a big increase in the number of Americans who attend college and university classes in

the evening or at night or weekends. Most of them are older than 25 years old and more have full-time or part-

time jobs. Many are in their thirties or forties.

     Why are so many people deciding to spend their time and money in order to continue their education? Most

are doing it because they believe more education will help them to get a better job. Some are industrial workers

whose factories have closed. They are learning new skills to prepare for other kinds of work. Some of the part-

time students are not pleased with the jobs they have. They are studying for new ones. Some have retired (退休)

and are looking for new kinds of jobs. Two of every three of the students older than 35 are women. Many of

them are returning to school after years of staying at home to care for children.

     Are older students good students? Most teachers say yes. They say older students really want to learn. They

ask difficult questions and are not pleased with simple answers. They often get high grades.
