Schools in isolated rural areas and inner cities are the hardest to staff, particularly those
serving minority or low-income students, according to recent data. Teachers in special education, math, science and foreign languages are especially needed. Shortages are greatest in the Southeast, Southwest and the West. With No Child Left Behind putting greater emphasis on having "highly qualified" teachers in every classroom, the competition among districts for teachers is likely to intensify the problem and present a challenge for rural districts.
