The processes used in identifying/diagnosing specific learning disabilities (SLDs) vary across settings and classification systems. Moreover, the theoretically and mathematically derived identification models (i.e., discrepancy model) have thus far not demonstrated adequate reliability and validity. The present study explores the utility of…

Although scholars have suggested that cognitive errors may plague school psychologists' decisions, there is little research documenting these effects or the extent to which school psychologists are trained to spot these biases. I conducted a study using experimental vignette methodology (EVM) in conjunction with a survey of knowledge, attitudes,…

Given the literature review on over and under representation of ELL students in Special Education, this research aimed to study how teachers identify between ELL students who present with language proficiency learning difficulties and students who might exhibit learning disabilities. This qualitative study added to existing literature on…

The aim of this study was to explore the variation in student behavior across the ED, LD, and OHI disability categories and to examine demographic, behavioral, and academic factors that may place students at risk for negative outcomes. This study used teachers' rating of students' in-class behavior to identify latent classes of students in the ED,…

This dissertation explores how federal education policies affect outcomes for special populations and their teachers. The first study uses a differences-in-differences design and data from the Stanford Education Data Archive to determine if "No Child Left Behind" (NCLB) waivers reduced district-level white-black and white-Hispanic…

The "Response to Intervention Guidance for New York State School Districts" (2010) document indicates Response to Intervention (RTI) is a mandated general education process intended to provide early interventions to struggling at-risk students. The multi-level RTI framework is structured to include targeted evidence-based interventions…

The passing of the Education of the Handicapped Act (EHA) of 1970, as well as subsequent education policy, including the Individuals with Disabilities Education Act (2004), have been pivotal to ensuring that both the civil and educational rights of students with disabilities continue to be promoted and protected within educational settings. In…

Psychoeducational assessment, and specifically cognitive testing, is important to the role of school psychologists; however, the utility of such testing has been called into question, and its future is unclear. Researchers are divided into two camps. One side grew disenchanted with cognitive testing after the failure of the discrepancy method to…

This disability category study was created to examine the relationship between the effects of inclusion with co-teaching methodologies on mathematics and language arts scores recorded from TCAP scores for 7th grade students who were found eligible for Special Education as having either a Specific Learning Disability or an Intellectual Disability.…

There is a great deal of research supporting Reading Recovery as a successful reading intervention program that assists below level first graders readers in closing the gap in reading at the same level of their average peers. There is a lack of research that analyses the cost-effectiveness of the Reading Recovery program compared to the cost in…

Previous "selective" meta-analyses of the literature relating to the IQ-achievement discrepancy model of specific learning disability identification have concluded that "underachieving" and "low-achieving" poor readers do not differ in any educationally meaningful way. Underachievers are those poor readers who qualify as learning disabled using an…

This study provides a description of the academic functioning levels and performance gains of adolescents (n = 423) attending a residential school over a seven year period using secondary data. Students ranged in age from 12 to 18 and represented a wide range of cultural and linguistic backgrounds. The vast majority of the sample were males (68%).…
