interventions; and use of these measures of student progress to inform instruction and make
educational decisions. A student is identified as having a Specific Learning Disability if he or she
displays insufficient response to scientific, research-based intervention as well as insufficient
progress toward grade-level standards (IDEA, 2004)
Discrepancy models and the Response to Intervention model are currently the primary
ways a student can be identified as having a specific learning disability (SLD). In Kentucky, if
schools use the discrepancy model, school psychologists must use the State-provided reference
tables, based on the cognitive assessment and achievement assessment pairings and their
correlations (Kentucky Department of Education, 2017, Reference Tables).
In contrast to the discrepancy and RTI models, Jenson (1998; 2006) gives credence to an
“information processing model,” which is becoming increasing popular (McGill, Styck,
Palomares, & Hass, 2016; Flanagan, Alfonso, Costa, Palma, & Leahy, 2018). The processing
model may also be referred to as “processing strengths and weaknesses” (Carmichael, Fraccaro,
Miller, & Maricle, 2014, p. 11). Sotelo-Dynega, Flanagan, and Alfonso (2018) state that
traditional identification of SLD relies on strengths and weaknesses, in relation to one’s
cognitive abilities (Flanagan, Alfonso, Costa, Palma, & Leahy, 2018, p. 608). The “processing
disorder causes academic deficits, and that it is not due to another disability or disadvantage”
(Hale & Fiorello, 2004, p. 179). When using this approach, the child is considered a
mini-computer. The examiner controls what the input to the computer and how it is presented,
either visually, verbally, by touch or in combination (Baum & Plata, 1976). The amount of
information the subject can reproduce allows for measurement of the central processing
functions compared to the normative sample. Dehn (2006) reported that identifying the
