The purpose of this study was to investigate variables related to the professional identity and career path of school-based vs. non-school-based doctoral-level school psychologists. Two hundred seventy-three psychologists trained as school psychologists completed a questionnaire developed to investigate their training, experience, and perceptions. Respondents differed little by employment setting (school-based vs. non-school-based) in reports of their training or experiences. However, significant differences were found among groups in two areas: ratings of relative importance of characteristics of employment setting, and perceived identity as a school psychologist.  相似文献

Many studies examine the development of infants born at risk for medical and developmental problems during the early years of life, but far fewer follow these children into their school years. This project compared high-risk vs. low-risk children in their performance on the WPPSI at pre- and postkindergarten levels. In general, both groups of children demonstrated increases in performance; however, their patterns of performance were different. The high-risk children showed increases predominantly in the Performance areas of the test, whereas the low-risk children demonstrated increases predominantly in the Verbal areas.  相似文献

A common method used to interpret raw scores is to convert them into percentile rank. The broad application of percentile rank in almost all norm-referenced tests, and the exclusive use in some tests, requires the conversion of raw scores. Because percentile rank is not a linear transformation of raw scores, percentile-rank transformation in the lower and upper part of the raw-score distribution relates percentile rank and raw scores differently than in the center of the raw-score distribution. This paper describes the popularity of using percentile rank and offers an interpretation of the use of percentile rank with normal and skewed score distributions.  相似文献

When a crisis occurs in the school setting, school officials must be prepared to handle the situation effectively and efficiently. One of the ways school officials can handle a crisis situation is through the use of crisis intervention teams. The steps in establishing a crisis intervention team in a school setting include: determining goals, performing a needs assessment, finding model programs, developing a membership pool, developing a training program, preparing and maintaining a list of resources and plans for support services, establishing a communication network, designating a base of operations, planning team meetings, keeping records, and implementing the phases of debriefing. A crisis management scenario is presented and discussed in terms of the steps.  相似文献

One hundred thirty-eight fifth-grade students from three upstate New York school districts were administered a 1930s version of the Pintner General Ability Tests: Verbal Series. Scores from this test were compared and correlated with scores from current IQ and achievement tests. The Pintner means were similar to those of the current IQ tests; the correlations of the Pintner with the other tests were of the same order as those typically reported among contemporary measures; and item difficulty, as indicated by rank order, appeared similar for the current sample and the 1930s norm groups. The findings are discussed with reference to research that has shown sharp increases in IQs of Americans since the 1930s and questions concerning changes in mental ability measures.  相似文献
