The Bracken Basic Concept Scale-4th Edition: Receptive™ (BBCS-4: R™) and Bracken School Readiness Assessment™-4th Ed. (BSRA-4™) are developmental assessments used to assess children’s understanding of a wide range of concepts used in daily classroom conversations, teacher directions, and school curricula. Concept knowledge is a powerful predictor of language development, cognitive functioning, and school readiness. Results of the BBCS-4: R and BSRA-4 are important for psychologists, speech-language pathologists, and early childhood professionals who assess developmental delays, as well as for educators seeking to determine a child's school readiness. This intermediate-level webinar will provide an overview of the development, test administration, and scoring as well as how to integrate BBCS-4: R and BSRA-4 as part of your assessment battery.
