The purpose of this study was to identify factors that should be considered in order to determine eligibility and appropriateness of TA(test accommodations) when a student with learning disability(dyslexia) wanted to provided TA to participate in high-stakes test such as KSAT. For this purpose, I conducted a literature review of domestic and foreign studies with students with (learning) disabilities. The results of this study are as follows: First, it is confirmed that legal, clinical, and professional rationale should be supported as to why students should be provided with TA for them. Second, although various types of TA can be provided to students with learning disabilities(dyslexia), it is important that the TA conditions be fair and valid. Third, by confirming the effect of TA(including time extension), that is, ‘differential score boosting’, domestic and foreign researches confirmed the necessity of TA for students with learning disability(dyslexia). Based on the results of the study, I suggested that students with learning disabilities(dyslexia) can be provided various types of TA in addition to the time extension, that examiner must follow professional standards, that the need for a well-designed study to determine the appropriate time extension, and that the need for the construction and operation of a multi-disciplinary committee for the decision-making of the necessity and appropriateness.
