Some schools attended by children with severe disabilities are being sanctioned under NCLB for poor attendance that educators say is tied more to students' fragile health than truancy. "We know that there are legitimate reasons for [students] to be home," said Tina Shrewsbury, coordinator for a Maryland school that serves many children with physical and cognitive disabilities. "They're going to [medical] specialists. ... They're having lab tests done. They're being hospitalized."
