This article argues that school psychology programs must prepare future school psychologists to address the needs of our increasingly diverse society. Providing training and field experiences that are grounded in multicultural practices, research, and advocacy will foster greater competence in addressing diverse schools', students', and families'…

Many contemporary learning disabilities (LD) experts advocate a multitiered service delivery system. Included in this formulation is the obligation to deliver for each struggling student increasingly sophisticated and intensive services before special education is considered. For students who evidence failed response to intervention, an…

The articles in this special Practitioner's Edition of "Psychology in the Schools" share the application of sound educational and behavioral practices in real school and classroom contexts. Given this emphasis in these articles on the applied use of behavioral practices, the purpose of this brief commentary is to highlight and comment on some of…

Based on observations of the Chinese educational system in the summer of 2002, I argue that comparisons of the performance of students in the United States and China, and by implication, of students in the United States and other East Asian countries, have been too homogeneous. I discuss four variables that could be included in future research…

In this commentary, we examine the articles in this special issue in terms of a continuum of research to practice strategies currently used in school psychology. On one end of the continuum is the "publish and hope" approach, and at the other end is the "change the organization to fit the innovation" approach. We present the concept of innovation…

We argue that the existence of the gap is perhaps a result of an overallegiance to the medical model and the lack of measurable criteria regarding the definition of an educated and psychologically healthy student. Further, an additional and equally daunting problem for school psychological practice is that it is influenced by general education…

The authors were asked to respond to the shortage of school psychologists from the perspective of the Division of School Psychology of the American Psychological Association and the American Psychological Association (APA), and also chose to address the larger issue of the shortage and lack of accessibility of mental health services for children…

In this paper, we respond to the criticisms and concerns raised by D.V. Cicchetti, A.S. Kaufman, & S.S. Sparrow (this issue) in their review of the PCB literature, with particular attention to our own research in Michigan. We agree that multiple comparisons and functional significance are issues that would benefit from more discussion. However,…

This paper comments on a critical review of cohort studies on PCB-related neurodevelopmental deficit in young children by D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (CKS). Major points of criticism of CKS, namely alleged violation of statistical principles, presumed lack of clinical significance of findings, and alleged insufficient control of…

The aim of the review of D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (funded by the General Electric Company; this issue) is to "evaluate [the] literature relating the effects of prenatal and postnatal exposure to polychlorinated biphenyls (PCBs) upon neurobehavioral, health-related, and cognitive deficits in neonates, developing infants,…

D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) use six criteria to evaluate the published findings from seven different studies of PCB exposure and neuropsychological function. They point out a number of weaknesses or flaws in each study and conclude that these weaknesses make the overall conclusion that PCB exposure negatively…

The seven cohort studies of the relation between prenatal and postnatal exposure to polychlorinated biphenyls (PCBs) to cognitive, neuropsychological and behavioral development have suggested that exposure to PCBs can cause persistent changes in cognitive functioning. D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) apply six scientific…

D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) examine various technical issues related to six studies of perinatal PCB exposure and neurodevelopment and one study of adult PCB exposure and motor function. They raise questions about possible imperfections of the studies, but many of their assertions are unsupported or frankly…

This invited response to the paper by D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (CKS), and the responses by the investigative teams of the studies criticized by them, addresses specific errors of logic and interpretation by CKS, and integrates comments made by the study investigators. CKS provide a flawed analysis of the literature on the…

In this paper we address the points raised by groups of scientists who were invited to respond to our initial critique of polychlorinated biphenyl (PCB) research in this special issue. In that article, we applied six objective criteria to more than two decades of published PCB research and concluded that much of the research was badly flawed. The…
