Autism is an extensively multifaceted clutter. The core deficits in the areas of communication, social behavior, and excessive repetitive behavior could incline children with autism spectrum disorders to present problem behavior. Children with autism are misdiagnosed in Pakistan and majorities are placed in schools for children with mental retardation. Special education teachers are not fully trained to teach children with autism according to their needs. The objectives of the study were to develop language and social skills of children with autism in Pakistan and to measure the efficacy of Teaching Learning Resource (TLR) for children with Autism in Pakistan. Researchers have developed a TLR package which focused on visual based learning and applied with Pre –Post design (ABA) to determine the effectiveness of its usability. Researchers have selected two groups (experimental group N=5, control group N=5). Only the experimental group took three months (15 hours per week) training. The qualitative research methods such as portfolio assessment and case study method were used to report developmental changes while paired samples t-test was applied to measure the effectiveness of TLR package with regards to performance of the children with autism. The results of the study showed significant improvement in the socialization and communication skills of children in the experimental group. This study concludes that after proper adaptation, TLR package is likely to be successful in training autistic children in particular and children with developmental disabilities in general at various situations like home, in a classroom situation and in distance training program.
