a) is not primarily the result of:
▸ impairment of vision;
▸ impairment of hearing;

c) may be associated with one or more conditions diagnosed as:

❑ Giftedness *(IG)
An unusual advanced degree of general intellectual ability that requires differentiated learning experiences of a depth and breadth beyond those normally provided in the regular school program to satisfy the level of educational potential indicated.
❑ Mild Intellectual Disability *(IMD)
A learning disorder characterized by:
a) an ability to profit educationally within a regular class with the aid of considerable curriculum modification and supportive service;

❑ Developmental Disability *(IDD)
A severe learning disorder characterized by:
a) an inability to profit from a special education program for students with mild intellectual disabilities because of slow intellectual development;
b) an ability to profit from a special education program that is designed to accommodate slow intellectual development;
c) a limited potential for academic learning, independent social adjustment, and economic self-support.
❑ Physical Disability *(PD)
A condition of such severe physical limitation or deficiency as to require special assistance in learning situations to provide the opportunity for educational achievement equivalent to that of pupils without exceptionalities who are of the same age or developmental level.
❑ Blind and Low Vision *(PV)
A condition of partial or total impairment of sight or vision that even with correction affects educational performance adversely.
❑ Multiple Exceptionalities *(M)
A combination of learning or other disorders, impairments, or physical disabilities, that is of such nature as to require, for educational achievement, the services of one or more teachers holding qualification in special education and the provision of support services appropriate for such disorders, impairments, or disabilities.
