Impact of Early Intervention on Children with Autism Spectrum Disorders as Measured by Inclusion and Retention in Mainstream Schools



To follow up the school/educational status of children with a primary diagnosis of Autism Spectrum Disorders (ASD), who had been enrolled in an Early Intervention (EI) program for 1–3 y, before the age of 6.


Data was collected through a questionnaire covering three specific areas—the families’ success in following the recommendation given on completion of the EI program, issues in schooling and feedback on the EI program. The contact modes included email, post, telephonic interviews and face-to-face interviews.


One hundred and two of the 296 children responded to the questionnaire. The responses were analyzed to identify, the number of families who had completed the program and were able to follow through with the recommendation given on completion of the EI program, difficulties faced if any, family feedback on the program and the additional help that they would have liked to receive. The reasons for failure to comply with the recommendations were analyzed. Of the 102 children who responded seven had dropped out midway through the program and 10 had discontinued after one year. Of the remaining 85 who completed the program, 71 were advised mainstreaming (83.5 %) and 14 were advised special school (16.5 %). Sixty-five of the 71 children, who were advised to enroll their child in the mainstream, were in regular school. 76.5 % of the children who completed the EI program were integrated in regular schools, 2 to 7 y after having completed the program.


EI helps in enrolment and retention of substantial numbers of children with ASD in mainstream schools.
