Evidence-based Evaluation of SLD for English Learners

This advanced workshop will outline the critical issues involved in nondiscriminatory evaluation of Specific Learning Disability (SLD) with English learners and will include presentation of a practical framework for assessment, an evidence-based approach for determining test score validity, and a full operationalization of criteria and procedures for determining SLD using a pattern of strengths and weaknesses (PSW) approach. These elements will be presented and described within the context of contemporary tools and research that are supported by use of X-BASS and C-LIM to facilitate evaluation of the validity of test scores and PSW analyses for SLD, as well as supporting evaluation of language with the Ortiz PVAT to address the concept of "difference vs. disorder." Case studies will be used to illustrate procedures, decision points, and integration of these contemporary tools and provide a step-by-step guide for their use in evaluating ELs, regardless of an evaluator’s own bilingual abilities. Overall, participants will receive specific guidance on establishing psychometric, theoretical, and construct validity of test scores, as well as in organizing data for SLD identification within a modern PSW model. Participants are encouraged to bring their laptops to receive hands-on experience in using the X-BASS and C-LIM software.
