All students are expected to participate in accountability systems and multiple options exist for students with disabilities, including taking the general large-scale assessment with and without accommodations and taking an alternate assessment. Using a secondary analysis of the National Longitudinal Transition Study-2 (NLTS2), the researcher…

Although federal regulations require testing students with severe cognitive disabilities, there is little guidance regarding how technical quality should be established. It is known that challenges exist with documentation of the reliability of scores for alternate assessments. Typical measures of reliability do little in modeling multiple sources…

Little research has precisely defined the population of students participating in alternate assessments based on alternate academic achievement standards (AA-AAAS). Therefore, the purpose of this article is twofold: (a) explicate the findings of a multistate study examining the characteristics of the population of students participating in…

Students with disabilities have traditionally achieved to a lesser degree than have their nondisabled peers. Since the 1950s the federal government has enacted laws to provide free, appropriate public education to students with disabilities. In the first decade of the 21st; Century the government has produced legislation requiring schools to be…

The study of measurement invariance in polytomous items that targets individual score levels is known as differential step functioning (DSF; Penfield, 2007, 2008). DSF methods provide specific information describing the manifestation of the invariance effect within particular score levels and therefore serve a diagnostic role in identifying the…

According to the amendments of the Individuals with Disabilities Education Act of 1997, students with severe cognitive disabilities could no longer be omitted from standards-based reform but an alternate assessment needed to be administered (Arnold & Johnson, "Validating an Alternate Assessment," 2007, p. 266). The purpose of the…

This study is examining student eligibility for and participation in alternate assessments, the technical quality of the alternate assessment instruments and implementation procedures, the alignment of assessments with content and achievement standards, and the use and effectiveness of alternate assessments in measuring student outcomes. The…

The National Study on Alternate Assessments (NSAA) was mandated by the Individuals With Disabilities Education Improvement Act of 2004 (IDEA). Specifically, the law called for a "Study on Ensuring Accountability for Students Who Are Held to Alternative Achievement Standards" to examine: (1) the criteria that states use to determine…

This report describes one approach toward setting standards to determine performance level cut scores for an alternative assessment for students with disabilities. First, it considers requirements for inclusion of students with disabilities in educational assessments under the Individuals with Disabilities Education Act. The proposed methodology…

Accountability for students with disabilities who receive special education services is now a result of policy requirements in the Individuals with Disabilities Education Improvement Act (IDEA) of 2004 and the No Child Left Behind Act (NCLB) of 2001. Together these pieces of federal legislation require that students participate in statewide…
