What is the discrepancy model for identifying learning disabilities?

The discrepancy model is a way to capture and compare a student’s scores on different types of tests. It compares assessments of a child’s intellectual ability ( IQ ) with how much progress he’s making in school (his academic achievement).

What is the difference between the discrepancy model and RTI?

The Discrepancy Model is a more traditional method used to identify a learning disability through cognitive and academic achievement testing. RTI focuses on the student’s inability to respond to interventions and/or instruction within the classroom setting.

How is eligibility for special education determined?

Students determined eligible for special education services must meet all three of the following criteria: The student must have a disability or disabilities. The student’s disability/disabilities adversely affect educational performance.

Why is it still considered best practice to determine a students IQ score in the identification of a learning disability?

Why is it still considered best practice to determine a student’s IQ score in the identification of a learning disability? For some students with intellectual disabilities, the cause of the disability is unknown.

What is IQ-achievement discrepancy model?

The IQ-achievement discrepancy model is the traditional method used to determine whether a student has a learning disability and needs special education services. The discrepancy model is based on the concept of the normal curve (click here for a review of the normal curve).

How do you calculate severe discrepancy?

To find out how large the discrepancy between your child’s test scores must be, multiply the standard deviation (15) by the multiplier (1.5), for a total of 22.5 points. Then, add the standard error points (4) for a total of 26.5.

What is the wait to fail approach?

A diagnosis of dyslexia in school is primarily based upon a “wait-to-fail-approach.” This approach requires a child to demonstrate a significant struggle to learn to read over a prolonged period of time before more intensive (quality and quantity) interventional strategies are discussed and eventually put into place.

What are the 3 questions that need to be answered when determining eligibility for special education?

In general, to qualify for special education in California, (i) the child must have one or more eligible disabilities; (ii) the disability must negatively affect her/his educational performance; and (iii) the disability must require special education and related services.

What is IQ-achievement discrepancy?

The IQ-achievement discrepancy model assesses whether there is a significant difference between a student’s scores on a test of general intelligence (e.g., an IQ test such as the WISC-IV) and scores obtained on a test of academic achievement (e.g., the Woodcock-Johnson Achievement Test).

What is the severe discrepancy model for special education?

Severe Discrepancy model for special education eligibility is the difficulty associated with the definition of “adequate progress” within each tier of the RTI model (Zirkel & Thomas, 2010). Using this method stipulates that if a student does not make adequate progress he or she would then be referred for a special education evaluation in

When did the discrepancy model become a law?

The discrepancy model was part of the Individuals with Disabilities in Education Act (IDEA) when it became law in 1975. It was created so that schools would have a way to figure out which students were eligible for special education. For decades, schools were required to use the discrepancy model.

What are the state regulations for special education?

While the definition of SLD remains unchanged, state special education regulations provided expanded options for determining SLD eligibility in 2007. These regulations address the eligibility determination for SLD ( WAC 392-172A-03045 through WAC 392-172A-03080) that provide for the use of: 1.

What is the severe discrepancy regression formula for SLD?

Appendix A provides the severe discrepancy regression formula, and Appendix B contains an updated recommended list of tests and subtests for use within severe discrepancy eligibility determinations. II. Required Components for Initial SLD Eligibility Determination
