Language is the system someone uses to communicate with another person. This covers the origins and construction of words, their definitions, and the use of language in various contexts. In normally developing children, receptive language skills are typically much more advanced than expressive language skills. However, some studies found that toddlers and kids with ASD had a relatively greater impairment in receptive language skills than in expressive language skills. The study will evaluate the ABLLS-R (Assessment of Basic Language and Learning Skills test) and Portage guidance and compare their effectiveness in developing the Receptive Language Skills in children with Autism Spectrum Disorder (N=12).

The study will follow the Randomized control trial study design and a purposive sampling technique will be used. Data will be collected from a special education centre BASES (Behaviour and special education services), Lahore. Children with autism spectrum disorder with mild to moderate severity level will be included in the study. The age range of the children will be from three years to seven years. Children with other neurological disorders or any comorbid conditions will be excluded from the study. The consent form will be filled out by parents of children who meet the inclusion criteria. The autism screening tool will apply by the speech and language pathologist. Half of the total number of children will receive therapeutic intervention under ABLLS-R protocol and other will receive Interventions under portage guide protocol. The data will be analysed by using SPSS 22 statistical software. The results of the study of both the groups will be compared and conclusion will be made on the basis of results. Receptive language skills are crucial for communication and social interaction. Research comparing these assessment tools can contribute to the development of more effective early intervention programs for children with ASD. By identifying the most appropriate assessment tool and intervention strategies, these programs can be better designed to support early language development and promote better long-term outcomes. By understanding the strengths and limitations of each assessment tool, professionals can create more individualized treatment plans for children with ASD
