Session
Information:
This workshop is designed for practitioners with beginning and intermediate level knowledge in Cross-Battery Assessment (XBA) procedures, as supported by use of X-BASS and C-LIM to assist in identification of specific learning disability in both native-English and English learner populations. The session will outline the issues involved in Specific Learning Disability (SLD) evaluation and present a comprehensive, research-based method for determination based on a Pattern of Strengths and Weaknesses (PSW) approach known as the Dual-Discrepancy/Consistency model which is operationalized within X-BASS software to ensure a systematic, defensible, and nondiscriminatory approach for SLD identification. Participants will be given instruction in a step-by-step manner covering the foundations of the Cattell–Horn–Carroll (CHC) theory that underlies XBA principles, the basic psychometric rules that govern construction of composites that adequately represent desired theoretical constructs, guidelines for integration, analysis, and interpretation of test scores, and instruction on the use of the various modules within X-BASS in conducting evaluations that meet requirements for a processing strengths and weaknesses approach. The process of evaluation will be further illustrated via the use of two, guided case study examples, one with a native-English speaker and one with an English learner. The knowledge and skills gained will assist practitioners at the beginner or intermediate level in conducting comprehensive, organized, reliable, and efficient (CORE) evaluations of SLD that constitute current best practice.
