The national assistance system for poor college students is getting more effective as proved by fewer phone calls to the hotline of the National Center for Student Assistance Administration.

     "Poor college students and their parents are getting more satisfied with the national assistance system," said Ma Wenhua, deputy director of the administration, on Saturday. Over the past three years, the hotline received 8,488 calls. Statistics show 62 percent of the calls were made to ask about the funding policy, while 38 percent (3,200 calls) complained local colleges had failed to abide by the rules to support the students.

     Complaints were seen a year-on-year decrease from 2006 to 2008. Ma said some poor families might still overlook what they should do to get support for their child. To ensure education equality, the government has introduced a set of favorable policies to help poor students, such as scholarships, grants, student loans, tuition waivers(学费全免) and the work-study programs under which poor students are helped out in libraries, teachers' offices or service departments to earn money.

    Statistics show the government spent 29.3 billion yuan last year to aid college students, up 7.6 percent from the previous year. Around 40 million persons of college students received the national aid.

    The Ministry of Education of the government would ensure that no students drop out of colleges or universities because of poverty.

    Among the 20 million students in the country's public and private universities and colleges last year, about 20 percent came from poor backgrounds, official figures show.
