The Individual Growth and Development Indicator (IGDI): Which One Doesn't Belong (WODB) task is an early comprehension screening assessment designed for use in pre-Kindergarten multi-tiered systems of support. This article summarizes the purpose, procedures, and evidence base currently available in the literature to support the WODB task.…

The purpose of this extended commentary article is to frame the set of studies in the first of two issues and recommend areas of inquiry for future research. This special series issue features studies examining the technical qualities of formative assessment procedures that were developed to inform intervention. This article intends to emphasize…

Assessment permeates many aspects of our educational society. With the passage of federal legislation (i.e., No Child Left Behind Act of 2001 and Individuals With Disabilities Education Improvement Act of 2004), assessment in the form of accountability is ever present in our K-12 educational system. Current assessment practices should be used in…

Response-to-intervention (RTI) models incorporate a screening process to identify students who appear to be at risk for learning disabilities (LDs). The purpose of this position article is to incorporate what is known about screening into a flexible, yet comprehensive screening system to help school psychologists and other school administrators in…

This paper addresses several objectives of the special issue on universal screening by addressing gaps in the current research base concerning universal screening for mental, emotional, and behavioral health and by providing a framework for addressing the limitations of extant approaches. Specifically, an adaptive model of behavioral assessment…

The majority of the literature on universal screening in education is devoted to academic screeners. However, research clearly indicates that other aspects of student functioning are closely associated with outcomes inside and outside of school. As a result, there are gaps in the current literature that call for additional research extending…

Treatment validity is a frequently neglected topic of screening instruments used to identify autism spectrum disorders. Treatment validity, however, should represent an important aspect of these instruments to link the resulting data to the selection of interventions as well as make decisions about treatment length and intensity. Research…

Spelling is an important, but often overlooked, component of literacy instruction and development. Although it is related to other aspects of literacy, there are independent theories of spelling development as well as assessment and instructional strategies that align with these theories. This article summarizes the rationale for linking…

Implementing a Response to Intervention (RTI) system could improve overall student achievement and the way in which students with disabilities are identified. In order to evaluate the effectiveness of an RTI system (i.e., "Is our RTI system accomplishing its stated goals?"), a set of data-based indicators are needed. This paper will describe a set…

A new professional credential, the Nationally Certified Educational Diagnostician (NCED), was established in 2006 for assessment specialists known as educational diagnosticians. The first cohort of 511 diagnosticians from 11 states received NCED certificates in January 2008. Discussed in this article are several issues of concern related to…

While formal, standardized assessment instruments provide valuable and necessary information about students' various abilities and skills, the use of informal and qualitative assessment approaches has the benefit of leading directly to instruction based squarely on an individual student's needs, strengths, and existing skills. This article…

Rubrics are an integral part of many writing programs, and they represent elements of good writing in essays, stories, poems, as well as other genres and forms of text. Although it is possible to use rubrics to teach students about the processes underlying effective writing, a more common practice is to use rubrics as a means of assessment, after…

Accurate spelling is a complex act that requires cognitive and linguistic knowledge of the phonological, morphological, syntactical, and semantic principles of our language. Students with disabilities frequently exhibit spelling difficulties related to language learning disorders and inefficient cognitive processing. These difficulties often are…

The intervention validity of cognitive assessment batteries is considered within an historical context to identify what the evidence supports (knowns), what cannot be known (unknowables), and what is not yet known (unknowns). Two ways cognitive batteries could inform intervention are identified: a disordinal (i.e., aptitude-treatment interaction)…

Poor math performance is a major concern leading the current educational reform agenda. Many educational math critics are claiming a math crisis. Researchers and school personnel are trying to resolve this crisis. Some are looking at curriculum-based evaluation (CBE) as a process for solving this problem. CBE and curriculum-based measurement (CBM)…
