In this paper, an analysis is carried out to review the comparison of the mean EEG power between groups of ASD students in terms of duration <3 years, 3 to 9 years and =9 years, so that a significant difference can be seen. In this study, 33 ASD students were observed using EEG, which had a sampling frequency of 500 Hz with eight electrodes at points F3, F4, C3, C4, P3, P4, O1, O2. The results show that the longer the child gets EIBI, the absolute power of the delta and slow theta waves will decrease. Relative power results also show that the longer the duration of the student obtaining EIBI, the higher the percentage of the emergence of alpha waves. So, the comparison of power EEGs based on group division for the duration of the intervention program, shows that EIBI has the potential to improve student quality.
