Some models use psychometric approach- use individual's achievement score and compare it with a sample of same aged peers. According to CHC model, weakness is defined as performance below average range. Flanagan and Alfonso (2015) revised CHC in form of DDC or X-BASS and program uses statistically significant critical values for cognitive weaknesses. D/CM model defines cognitive weakness as a combination of intraindividual and normative appraisals. ]]> 2021-02-16 01:14:57 UTC https://padlet.com/ltipton38/7lscxlow3qd3/wish/1205209987 Pauline https://padlet.com/ltipton38/7lscxlow3qd3/wish/1205231541 Miciak et al (2015) found that using different assessemnt measures in C/DM model resulted in low agreement of diagnostic decisions.

(2016) highlight existing literature, which revealed that high diagnostic specificity was found across all models with only 1-2% of the population meeting SLD criteria. The high specificity contributed to an inflated error rate. Readers are reminded that multidisciplinary evaluation teams must remember that there is going to be some degree of decision error when cut-scores are used to diagnose SLD. https://padlet.com/ltipton38/7lscxlow3qd3/wish/1209110987 2021-02-16 23:59:22 UTC https://padlet.com/ltipton38/7lscxlow3qd3/wish/1209110987 Verenice https://padlet.com/ltipton38/7lscxlow3qd3/wish/1213903726 There is a need for users to integrate multiple sources of data in order to enhance the ecological and treatment validity of diagnostic decisions.]]> 2021-02-18 05:55:09 UTC https://padlet.com/ltipton38/7lscxlow3qd3/wish/1213903726 Ruby https://padlet.com/ltipton38/7lscxlow3qd3/wish/1221876784 PSW model begins at 8:30]]> 2021-02-20 18:45:32 UTC https://padlet.com/ltipton38/7lscxlow3qd3/wish/1221876784 Ruby https://padlet.com/ltipton38/7lscxlow3qd3/wish/1221896182 School psychologists must
have advanced training and preparation in the theory of cognitive abilities, causal cognitive–achievement relationships,
and advanced psychometrics and test interpretation for PSW to be implemented with fidelity in educational settings (Fiorello, Hale, & Wycoff, 2012; Weiner, 1989). But Decker, Hale, and Flanagan (2013) argued that school psychology training programs do not adhere to evidence- based assessment practices due to (a) an overemphasis
of interpreting the FSIQ score, (b) a gradual decline in the breadth and scope of the cognitive assessment training
sequence as a result of RTI implementation, and (c) poor training in linking cognitive test results to evidence-based
interventions. As a result, Decker et al. conclude that the cognitive assessment training sequence in many school psychology
programs must be overhauled if the promise of cognitive testing is to be realized with contemporary measures,
