Now, there is a growing movement to pay the students in American schools---in some cases, even just for coming to class.

Students at one school in New Mexico can earn up to three hundred dollars a year for good attendance. In Baltimore, Maryland, high scores in state graduation tests can be worth more than one hundred dollars. And a New Jersey school system plans to pay students fifty dollars a week to attend after---school tutoring programs.

Schools that pay students can be found in more than one---fourth of the fifty states. Other schools pay students with food or other rewards.

Robert Schaefer is a public education director. He says paying students may improve performance in the short term, but students develop false expectations for the future. He sees a lack of long term planning in these programs because of the pressure on schools to raise test scores.

Public schools need to show improvement under the education reform law. Low---performing schools may lose their federal money; teachers and administrators(行政人员) may lose their jobs. Often these schools are in poor neighborhoods where getting students to go to school can be a continual problem.

Critics(评论家) say paying students sends a message that money is the only valuable reward. But some students say it makes school more exciting. And some teachers have reported getting more requests for extra help.

In two thousand four, the city schools in Coshocton, Ohio, launched a program. They wanted to see if paying elementary school students as much as one hundred dollars would help in passing the state exams.

Now, Eric Bettinger of Case Western Reserve University (EUCWRU) has reported mixed results. Math scores increased, but only white students were able to get paid. And there was no evidence of higher scores in reading, social studies and science. Official will decide later this year whether to continue the program.
