What are the advantages of the discrepancy model?

The Severe Discrepancy model allows educators to determine if a student's inadequate progress is commensurate with his or her cognition and whether the student is working to his or her potential.

What is an advantage of the IQ discrepancy model?

Advantages of the IQ-Achievement Discrepancy Model

A teacher does not have to spend a great amount of time in the identification process because a certified diagnostician or school psychologist conducts the IQ and achievement tests.

What is the discrepancy model used for?

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 they're making in school (academic achievement).

What is a discrepancy definition of reading disability What are the advantages and disadvantages of a discrepancy definition?

The discrepancy model lets educators determine whether a child requires special-education services. It basically measures how far a particular child has fallen behind his peers. Schools generally set their own criteria for how far a child must fall behind before special-education services are recommended.

What is the discrepancy model of the RTI model?

The RTI model utilizes evidence- based data. 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.

Jim Crawford: Comparison of the RTI and Discrepancy Model Approaches

What does the discrepancy model focus on the difference between?

The second method, the Discrepancy model, uses tests to determine if a significant discrepancy or difference exists between an intelligence (IQ) test and academic tests and performance (Marchant, n.d.).

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 ...

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 is a drawback to using a discrepancy approach?

A drawback to using a discrepancy approach to identify children with learning disabilities is: test scores may not represent actual ability. A major reason why students with learning disabilities do poorly on memory tasks is: strategy use deficits.

What is a discrepancy model may be used to quizlet?

The discrepancy model utilizes a difference between a student's intellectual ability and his or her achievement with which to identify learning disabilities.

What is the difference between PSW and discrepancy model?

A pattern of strengths and weaknesses (PSW) is one approach for determining specific learning disabilities (SLD). As opposed to the old-school discrepancy model, which tells clinicians if a student is performing more poorly than expected, PSW seeks to determine why a student is performing more poorly.

What is the traditional discrepancy model of learning disability assessment?

The discrepancy model: Through the traditional discrepancy model, a learning disability has been determined primarily through a combination of cognitive (intellectual) and academic (achievement) testing.

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.

What is the discrepancy model of a needs assessment?

Three models of needs assessment are described along with examples of each. The discrepancy model evaluates gaps between expectations of experts and the outcomes of the target population. The marketing model evaluates the fit between the consumer's desires and the ability of agencies to deliver services.

What is the difference between IQ discrepancy model and RTI?

The pros of the RTI model are that teachers do not wait until a child is failing before doing something different than general education, like they often did under the discrepancy model. RTI is a much more proactive, preventative model. Many schools begin RTI services as early as pre-school and kindergarten.

Does Texas use the discrepancy model?

Texas Guidelines for SLD

Consistent with the federal guidelines, the Texas guidelines require formal documentation of the provision of adequate general education instruction. The Texas guidelines are also flexible, permitting either a process based on RTI or one based on a discrepancy model.

What is the difference between pattern of strengths and weaknesses and discrepancy model?

Rather than using a discrepancy model contrasting intellectual and achievement test results, assessment specialists now incorporate a variety of methods to identify specific learning disabili- ties, including response-to-intervention, cognitive processing approaches, and the determination of a pattern of strengths and ...

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 response to intervention?

RTI benefits many students in the classroom and implementing it in your school can help students make progress. A huge benefit of RTI is that it helps students who may need intervention to be identified early so that they can get the support they need before they fall further behind.

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.

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 ...

What are three potential advantages of RTI?

Potential benefits cited by RTI proponents include (1) earlier identification of students with LD using a problem-solving approach rather than an ability–achievement discrepancy formula with the expectation of minimizing “wait to fail,” (2) reduction in the number of students referred for special education, (3) ...

What are the four components of the RTI model?

The National Center on RTI says the four essential components of a research-based framework for RTI are: universal screening, continuing progress monitoring, multi-level prevention system, and data-based decision making.
