A COMPARISON OF WISC-R SCORES WITH WAIS-R SCORES FOR MENTALLY HANDICAPPED STUDENTS WITH IQS BELOW 70 AND FOR REGULAR EDUCATION STUDENTS Kimberly A. Brennan, Ed.S. Western Michigan University, 1987
The purpose of the present study was to investigate the utiliza­ tion of WISC-R scores as a basis for placement and continuation of services for mental retardates in special education classes through­ out their school careers. A comparison of the WISC-R Verbal, Performance, and Full Scale IQs with the WAIS-R counterparts and a statistical analysis was conducted. Regular education students were also tested to determine if the two scales were equal.
The WAIS-R was found to yield higher Verbal and Full Scale IQ scores, but comparable Performance IQ scores. These results suggest that the differences between the two instruments for children of subnormal intelligence are educationally and statistically signifi­ cant, presenting the possibility of differential classification based on the intelligence test used. Future research should be con­ ducted to determine the full impact of this difference on vocational success and adjustment of the affected group, and in subjects of above-normal Intellectual functioning.

INFORMATION TO USERS
This reproduction was made from a copy of a docum ent sent to us for microfilming. While the m ost advanced technology has been used to photograph and reproduce this docum ent, the quality o f the reproduction is heavily dependent upon the quality of th e material submitted.
T he following explanation o f techniques is provided to help clarify markings or notations which may appear on this reproduction.
1. The sign or “ target” fo r pages apparently lacking from the docum ent photographed is “Missing Page(s)” . If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity.
2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials th a t should n o t have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame.
3. When a map, drawing or chart, etc., is part o f the m aterial being photographed, a definite m ethod o f “ sectioning” the material has been followed. It is customary to begin filming at the upper left hand com er of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again-beginning below the first row and continuing on until com plete.
4. For illustrations that cannot be satisfactorily reproduced by xerographic means, photographic prints can be purchased at additional cost and inserted into y o u r xerographic copy. These prints are available upon request from the Dissertations Customer Services D epartm ent.
5. Some pages in any docum ent m ay have indistinct print. In all cases the best available copy has been filmed.
