Special education during the early years is not about an intervention system or a special curricular model. Special education during the early years is about children who have special needs. Such children cannot be categorized, or thought of, as an homogeneous group. Children with special needs vary tremendously. Not only do they have the same type of variances as the general population (e.g. different interests, likes, dislikes, temperaments, abilities), they also vary by type and extent of disability.
