What are the pros 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.

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 are the disadvantages of the discrepancy model?

Cons: The discrepancy model can be rigid and inflexible, and may not accurately identify students who have learning difficulties that do not fit neatly into the model's criteria. The model relies heavily on standardized testing, which may not accurately capture a student's abilities or needs.

What is the significant discrepancy model?

The discrepancy model is what some schools use to determine whether kids are eligible for special education services. The term “discrepancy” refers to a mismatch between a child's intellectual ability and their progress in school. Some states now use other methods to determine who is eligible for services.

What are 4 benefits of using an RTI approach with struggling students?

Jim Crawford: Comparison of the RTI and Discrepancy Model Approaches

What are the benefits of using an RTI model?

An RTI approach has been suggested as a way to reduce referrals to special education by providing well-designed instruction and intensified interventions in general education, thereby distinguishing between students who perform poorly in school due to factors such as inadequate prior instruction from students with LD ...

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 discrepancy model and response to intervention?

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.

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 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.).

How is the discrepancy model different from patterns of strengths and weaknesses?

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 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.

What are the pros and cons of IQ tests?

For example, an IQ test may help to identify a child who is gifted, but who also has dyslexia or difficulties with visual processing (dual exceptionality). There are also limitations to IQ tests that professionals need to be aware of. The tests provide a 'snapshot' of a child's responses at the time of taking the test.

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 a drawback to using a discrepancy approach to identifying?

As a result, too few students are being identified as having learning disabilities. In summary, the discrepancy approach to identifying learning disabilities is limited by its wait-and-fail approach, lack of accuracy in test scores, and objectivity, leading to too few students being identified as learning disabled.

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.

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 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 the disadvantages of response to intervention?

One of the major disadvantages of RTI is that children who are performing at grade level are not identified. In the discrepancy model, a very bright child who was receiving a “C” could qualify for service because he/she was not performing at expectancy level.

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 discrepancy evaluation?

Share button. in evaluation research, the search for differences between two or more elements or variables of a program that should be in agreement. Reconciling these differences may then become a major objective in the program's development.

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).

How does RTI improve teaching overall?

RTI is designed to aid in the identification of learning disabilities and other learning and behavior problems and learning disabilities, improve instructional quality, and provide students with academic opportunities.

What is a drawback to using a discrepancy approach to identifying children with learning disabilities quizlet?

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.
