Toward Defining Discrepancies for Specific Learning Disabilities: An Analysis and Alternatives.
Algozzine, Bob; And Others
Three investigations examined the effects of IQ and chronological age (CA) on the calculation of severe discrepancy levels of 102 hypothetical and 125 actual severely learning disabled students (5 to 17 years old). Results indicated that IQ was highly influential on obtained severe discrepancy levels (SDLs) and related percentage discrepancies; that CA acted more as a moderator than as a predictor of the SDL and percent discrepancy levels; and that high levels of error can be expected if the SDL is calculated without regard to its discrepant level and used as a placement or evaluation criterion against which to measure achievement differences. A formula is proposed to obtain 50% discrepancy levels at various IQ and CA levels. (CL)
