The pilot questionary consisted of 15 items and was applied to 180 teachers and school authorities, the V-AIKEN method reveled 90% to 100% of reliability of the 15 items. The accuracy showed by Cronbach’s alpha measure was 0,960 in the same way, two components were determined in the variance corresponding to each fact. The first component constitutes 69% of variance and the second component the results gives 32 % of variance. Thus, the first component nominated Inclusion of students with Intellectual Disability integrates 8 items and the second called Learning Development involves 6 items, this generated an interaction of interface of 0,76 and 0.64. This revealed a moderated positive correlation of both components. In conclusion the Validating Search Processes is continuous. Therefore, this process demonstrated that the questionary is appropriated to learn about the teacher’s perception on intellectual disability and the learning process.
