Designed for professionals with foundational CASLLS knowledge, this intermediate-level training offers a deeper exploration into using the CASLLS (Cottage Acquisition Scales for Listening, Language & Speech) for targeted language intervention. Participants will strengthen their ability to interpret language samples, identify complex grammatical structures, and map these to the appropriate CASLLS strands. Through interactive practice and real-world examples, attendees will enhance their ability to use CASLLS for effective goal setting and ongoing language development support. This session is ideal for speech-language pathologists, educators, and interventionists ready to expand their CASLLS skill set and apply it more confidently in daily practice. Indicators 1, 4, 5, and 7 of the TEA Special Education Self-Assessment will be addressed.
