A meta-analysis of 128 studies of the relationship between self and achievement/performance measures reported correlations in the range of -.77 to .96 with an "average" correlation of .21. This average relationship was modified by several variables, including, among others, grade level of subjects, socioeconomic status, ethnicity, and…

A study involving 30 Argentineans with autism evaluated the validity of the Autism Diagnostic Inventory-Telephone Screening in Spanish (ADI-TSS). The final version of the ADI-TSS could be assessed in 20 to 40 minutes and demonstrated a high validity, high interrater reliability, and high internal consistency. (Contains references.)

Considers the development of an inter-rater reliability correlation comparing the judgments, or scores, or each judge to see if their observations are similar. Presents a case study of the Northville Public Schools' data for the 2000 MEAP (Michigan Educational Assessment Program) Writing Test. Concludes that in this case study the state fails both…

The meanings of reliability and validity as they apply to standardized measures are used as a framework for applying the concepts of reliability and validity to authentic assessments. This article sees reliability as scorability and stability, whereas validity is seen as students' ability to use knowledge authentically in the field. (DB)

An examination of the extent to which scores on the Stuttering Severity Instrument (SSI) for Children and Adults, Third Edition, accurately reflect 10 judges' observations of stuttering behaviors found that SSI scores obscured the wide range of judges' raw counts and did not accurately reflect the observational data from which they were derived.…

The behavior of each of 120 students in grades 9-12 was rated by 2 of the student's teachers using the Revised Behavior Problem Checklist. Results indicated a generally low to moderate degree of relationship among teacher ratings. It is recommended that clinicians collect behavioral ratings from many raters before reaching diagnostic conclusions.…

Forty-seven young children, 15 with disabilities, were observed 4 times for types and levels of engagement. Results indicated that engagement is difficult to measure through molecular data collection techniques because of error in dependability measures. The number of observed sessions could be increased to achieve generalizability, but increases…

Education remains heavily shackled by punitive, test-driven reform. Despite reasonable alternatives, testing increasingly drives educational accountability and reform. Standardization of direct writing assessments promotes scoring reliability and facilitates educational comparisons and rankings. However, standardized writing is not good writing,…

This study assessed the interrater reliability of a Swedish version of the Childhood Autism Rating Scale (CARS), an instrument for screening and diagnosis of autism. The CARS was used for rating autistic behavior by two investigators in 25 children. Results indicated fair to excellent agreement. Aspects of validity and reliability are discussed.…

The use of anti-epileptic medications (AEDs) is much higher in individuals with intellectual disabilities than in the general population. As many of these individuals rely on such medications, clinicians should consider psychometrically sound instruments for assessing adverse side effects of these medications as one aspect of routine clinical…

This paper reports on a case study which identifies and illustrates sources of difference in agreement in relation to reliability in a context of quantitative content analysis of a transcript of an online asynchronous discussion (OAD). Transcripts of 10 students in a month-long online asynchronous discussion were coded by two coders using an…

The research literature reveals that there are many factors that influence the consistency of assessors' or examiners' judgements. One issue that has not been considered is whether National Vocational Qualifications assessors' consistency of judgement is affected by different types of evidence. In this article, 15 Customer Service and 12 Assessor…

Purpose: To explore the utility of time-interval analysis for documenting the reliability of coding social communication performance of children in classroom settings. Of particular interest was finding a method for determining whether independent observers could reliably judge both occurrence and duration of ongoing behavioral dimensions for…
