This article presents the results of a comprehensive review of 128 studies on teaching reading to individuals with significant cognitive disabilities. The review compared these studies against the National Reading Panel's components of reading; although it revealed an inadequate consideration of the components of reading, it found strong evidence for teaching sight words using systematic prompting and fading. The reviewers considered not only the number of studies, but also indicators proposed for evidence-based practice and effect size. This study identified some high quality studies with strong effect size for comprehension and fluency, but only one phonics study was strong in both quality and effects. Additional research is needed to promote broader skills in literacy for this population.

This article reports on a comprehensive literature review and meta-analysis of 68 experiments on teaching mathematics to individuals with significant cognitive disabilities. Most of the studies in the review addressed numbers and computation or measurement. Within the computation studies identified, most focused on counting, calculation, or number matching. For the measurement studies, nearly all focused on money skills. Of the 54 single subject design studies, 19 were classified as having all quality indicators for research design (13 representing the National Council of Teachers of Mathematics Measurement standard and 6 representing the Numbers and Operations standard). These studies offer strong evidence for using systematic instruction to teach mathematics skills and for using in vivo settings.

For students to have full access to the general curriculum, they need the opportunity to learn academic content that links closely to the standards for their grade level. In this article, we synthesize what we have learned through our research on aligning instruction for students with significant cognitive disabilities with state's academic content standards. In finding these links between state content standards and instruction for students with significant cognitive disabilities, we have discovered that it is important to understand (a) the implications of current federal policy; (b) the evidence for academic learning by this population; (c) the nature of national and state standards; (d) the importance of starting with universal design and general education collaboration; and (e) the concept of alignment.

The purpose of the study is to determine the comprehensive knowledge base of national secondary principals related to special education issues. Using a survey developed from the empirical and conceptual literature for assessing fundamental and current issues in special education, data were collected from a national sample of secondary school principals. Overall, principals report being well informed in fundamental issues. Although the relationship between demographics and knowledge produced mixed results, principal practices have a positive relationship with knowledge of special education issues.

Current federal policy requires that students with disabilities participate in large-scale assessments and be included in schools' scores for adequate yearly progress. Students with significant cognitive disabilities may participate in an alternate assessment with alternate achievement standards, but these standards must be linked to grade-level content and promote access to the general curriculum. Because most research with this population has focused on nonacademic life skills, few guidelines exist for teaching and assessing skills that are linked to grade-level content. One challenge to developing research and practice in grade-linked academic content for students with significant cognitive disabilities is the absence of a clear conceptual framework. This article—developed by a team of special education, curriculum content, and measurement experts—proposes a conceptual definition and criteria for linking instruction and assessment to grade-level academic content.
