TACOMA, Wash. (AP) - A new study shows the number of homeless students in Washington schools is continuing to grow. The News-Tribune reports the advocacy group Columbia Legal Services has analyzed data reported by local school districts over five school years, ending with 2010-11. The state's large urban counties - Pierce, King, Snohomish, Spokane and Clark - educate more than half of the more than 26,000 homeless Washington students counted during the 2010-11 school year. But the researchers also found that almost a third of the state's homeless students lived in rural areas. Seattle had the most homeless students, with 1,324, followed by Tacoma, with 1,273.
