Child advocates say inadequate school funding and a lack of family support are causing poor performance in some Illinois schools.
The 2004 Illinois Kids Count report says that 40 percent of Illinois' public schools did not meet state learning standards last year. The poor performance can be attributed to major spending gaps among school districts.
The report says the state should reduce its reliance on property taxes and increase income taxes to improve the education system.
The report also says more than 46 percent of students are being raised in impoverished or low-income families. These students often have trouble concentrating on their studies.
