Autism
Autism means a developmental disability significantly affecting a child's social interaction and verbal and nonverbal communication, generally evident before age 3, that adversely affects learning and educational performance. Other characteristics often associated with autism are engagement in repetitive activities and stereotyped movements, resistance to environmental change or change in daily routines, and unusual responses to sensory experiences. The term does not apply if a child's educational performance is adversely affected primarily because the child has an emotional disturbance.

Significant Developmental Delay
Significant Developmental Delay is a disability area for children ages 3 through 9 who experience major delays in physical, cognitive, social emotional, communicative or adaptive development that is not otherwise specified in another disability area. SDD stands alone as a disability area. Therefore, if a child is determined to have a disability in the area of SDD, then no other area of educational disability would apply concurrent with SDD. (see more on SDD & S&L)
