This project aims at investigate the effects of an educational program- based on Art Education, on developing the vitality (libido) of the Mild Mentally Retarded Children, who are assumed to be studying in Mental Education Center, in Al Ahsaa. To achieve the aim of the project, the researcher has applied an experimental approach by comparing the performance and behavioral manifestations of the experimental and control samples in addition to compare the statistical differences between the performance of the experimental group in pre- posttests and measurements. The researcher used a set of tools and standards to test the validity of all the hypotheses and has reached the following results: 1. In posttests, there was statistically significant differences in development of sensory-motor activities apparent between experimental and control groups, reflected positively among the experimental group. 2. Measurements proved statistical significance for improvement in intelligence among experimental group, which confirms the effectiveness of the program. 3. The Statistical significant in post measurements did not show any improvement in the level of attention among the experimental group, confirming failure of the third hypothesis of this study.
