Such information about the differences could help educators to identify which types of students are more likely to be successfully mainstreamed. Also information about possible differences between the two groups could help educators in making decisions regarding how to plan for a successful mainstreaming program. The results of the study, presented in a table, show that there is a significant difference between the groups in seven areas: verbal quotient, cognitive, attentional enhanced, attentional reduced, motoric enhanced, motoric reduced, and global. Overall the basic difference is found in the area of verbal skills. This study indicated that a student's verbal composite quotient on the DTLA was the single most powerful factor that differentiated between being successful or not in the mainstreaming program. Therefore, educators need to plan mainstreaming programs which provide educational alternatives for the verbal deficiencies as well as on the resolution of the aggressive behavior. 1 table and 11 references (Author abstract modified)
