ABSTRACT

For students with severe dyslexia, developing a dyslexia assessment tools which can highlight strengths and weaknesses of students with dyslexia is necessary to provide efficient intervention. That is the reason why this study developed and standardized a dyslexia assessment tools. Thus, the dyslexia assessment tools composed of 11 testlets including variables related to reading achievement and reading cognitive processing ability was developed. Followings are the results of standardization of 121 students with reading disabilities. As a result of examining the reliability of the assessment tools, inter-item consistency was high at .985 and standard error of measurement was showed from .937 to 12.291. In terms of validity, content validity was established by domestic and overseas preceding studies. As a result of conducting correlation analysis, confirmative factor analysis, regression analysis and analysis comparing differences among groups, the developed assessment tools turned out to be appropriate. Concurrent validity and predictive validity were also quite high. This study suggests diagnosis criteria for dyslexia based on examination of reliability and validity. A summary of the study and some suggestions were discussed for further studies.
