A proposed federal regulation on testing students with disabilities provides details on the flexibility available to states and schools for meeting the requirements of the No Child Left Behind Act. While state education officials have generally welcomed the flexibility, representatives from advocacy groups for people with disabilities say they are concerned about potential erosion of academic standards for such students. The Department of Education announced a proposed regulation that would accompany a policy announced in the past. The proposed rules spell out in detail how states could allow certain students to be tested on modified achievement standards that are not as deep or broad as regular grade-level content. Opinions on this proposal are shared in this article.
