Why is the severe discrepancy model no longer used?

When IDEA was reissued in 2004, it didn't require schools to use the discrepancy model any longer. The discrepancy model doesn't take into account all the factors that may affect a child's academic achievement. Response to intervention and the processing deficit approach are two alternatives to the discrepancy model.

What is wrong with the discrepancy model?

Another limitation of the IQ-achievement discrepancy model is that it does not assess or inform the quality of instruction received by students. Some students may be identified as having learning disabilities when, in reality, they simply have not experienced classroom instruction that meets their learning needs.

What are some issues with the discrepancy model and wait to fail methods?

The major concerns of this group are that IQ tests are a poor index of intelligence, that the IQ–discrepancy approach is a “wait-to-fail” model since students must perform poorly for years before achievement scores are sufficiently below their IQ scores, and that low achievement for many students is actually caused by ...

What is the rationale for replacing the discrepancy model with RTI?

RTI or 'Response To Intervention' is a new approach to the identification of a learning disability which is intended to alleviate the problems associated with the discrepancy model. With RTI, there is no need to formally evaluate cognitive abilities or academic achievement.

Which states do not use the discrepancy model?

The federal regulation requiring a severe discrepancy between intellectual ability and achievement appears in the SLD classifica- tion criteria for 48 of the 50 states. Only two states do not have the discrepancy requirement in their state rules (IA and LA).

What model replaced the severe discrepancy model?

The discrepancy model doesn't take into account all the factors that may affect a child's academic achievement. Response to intervention and the processing deficit approach are two alternatives to the discrepancy model.

Why is the discrepancy formula no longer used to determine if someone has learning disability?

Discrepancy formulas fail to identify children with learning disabilities who show no discrepancy between achievement and intelligence test scores. Discrepancy formulas have never been empirically validated.

How is the severe discrepancy model different from 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.

What is considered a severe discrepancy?

(a) A severe discrepancy is defined as a 50 percent or higher probability of a two standard deviation discrepancy between general cognitive ability and achievement in one or more of the areas identified in ARM 10.16.

What is a drawback to using a discrepancy approach to identifying?

A drawback to using a discrepancy approach to identify children with learning disabilities is: test scores may not represent actual ability.

Why was the discrepancy model is sometimes referred to as the wait to fail model?

In this “wait-to-fail” model, struggling learners do not receive needed services as soon as their difficulties are evidenced, and instead they are set up to fail for several years until their achievement gap is wide enough for them to qualify for special education services.

What are the advantages of the discrepancy model?

Objective and Easy to Understand. The discrepancy model may have limitations, however, it has an advantage over alternative methods in that it is relatively simple. Also, it is an objective measurement and therefore can be applied evenly by many educators across even more students.

Why is RTI bad?

Chief among those concerns is that RTI models as originally conceived are not working to the advantage of students with dyslexia and other learning disabilities. They characterize RTI as a "fad” that lacks sufficient research support or implementation guidance from federal, state, or local agencies.

How many points is a severe discrepancy?

If there is between a 20-22 point difference (1.5 standard deviation), this is a strong indication that the student has a learning disability. The discrepancy must be corroborated by other evaluation information, such as from other tests, scales, instruments, observations, and work samples.

What is the discrepancy model for identifying dyslexia?

The revised discrepancy method described in this study can be used by researchers to identify students in their studies who have dyslexia and that most researchers might agree are prototypical examples of dyslexia (i.e., low reading ability, higher cognitive ability, and a difference of more than 1.0 standard deviation ...

How do you determine severe discrepancy?

Determine if a severe discrepancy exists

Compare the student's age-based achievement score to the criterion discrepancy score. Where the age-based achievement score is equal to or smaller than the criterion discrepancy score, a severe discrepancy is indicated.

Does NJ use the discrepancy model?

Although New Jersey state regulations allow for both the Severe Discrepancy model and Failure to Respond to Intervention as permissible in SLD identification, most school districts employ the Severe Discrepancy model, with wide variability regarding criteria and questionable fidelity and integrity.

What is the primary method used to assess severe discrepancy?

Currently, the process of establishing a severe discrepancy typically involves the administration of individualized ability (IQ) and academic (achievement) tests and a direct comparison of obtained standard scores (generally based upon a student's age rather than grade placement).

What are the two models of RTI?

The two most commonly used RTI approaches are problem solving and standard protocol. Although these two approaches are sometimes described as being very different from one another, they actually have several elements in common.

Why is RTI often erroneously mistaken for special education?

Why is RTI often erroneously mistaken for special education? Because RTI is focused on streamlining the special education referral process.

What does severe discrepancy compare a student's ability with?

Discrepancy analysis compares the student's cognitive ability with the student's academic achievement to determine if a significant difference between ability and achievement exists. This process was used to identify students with disabilities and compares a student's ability scores with achievement scores.

Which model of disability views disability as difference not deficit?

The social model of disability says that disability is caused by the way society is organised, rather than by a person's impairment or difference. It looks at ways of removing barriers that restrict life choices for disabled people.

What are the two methods to identify learning disabilities?

There are two primary methods of diagnosing a child with a learning disability: the severe discrepancy model, and the response to intervention (RTI) model.

What IQ is considered a learning disability?

a) Learning disabilities are heterogeneous conditions, but are defined by 3 core criteria: lower intellectual ability (usually defined as an IQ of less than 70), significant impairment of social or adaptive functioning and onset in childhood. the DSM-IV term 'mental retardation' with 'intellectual disability'.
