The present study aims to identify the effectiveness of a counseling program based on the use of the Montessori method on the environmental adaptive behavior in a sample of children with mild intellectual disabilities, identifying also the differences in the level of behavioral adaptation in a sample of children on the adaptive behavior scale pre/post application of the program. The researchers define a sample of (40) items, applied to a sample consisting of (40) children with mild intellectual disabilities, aged between (10-12) years, selected from boys, divided equally to (20) experimental samples and (20) control samples, from Al-Ghafir Foundation for people with special needs. The researcher has used the (experimental) method and applied the scale of adaptive behavior. The research has come to several results, the most important of which is that there is a statistically significant correlation between the average scores of the control group and the experimental group, regarding the post application of the total adaptive behavior scale. There are statistically significant differences between the average scores of the experimental group, regarding the post/ follow up application of the adaptive behavioral scale. There are statistically significant differences between the average scores of the control group and the experimental group regarding the post-application of the total behavior scale, in favor of the experimental group. The research reached a set of recommendations, the most important of which are: the necessity of providing the necessary tools for developing skills for children with disabilities within government institutions, setting a special budget
