Nevertheless, in urgent cases according to the nature of the disability, the handicapped students sit in fixed suitable places whether at the front or the back of the class.• Handicapped students sit close to the main exits of the class to be able to evacuate in case of emergencies.Construction Facility: Room number (234 A) is allocated and equipped with the essential educational tools for handicapped students.Academic Support:• Dr. Iman Gamal Morsi is appointed as an academic supervisor for handicapped students.Constant follow ups are done for handicapped students after each assessment to evaluate their academic level of achievement. 7- Student Assessment a- Procedures used 1.
