Is the discrepancy model still used?

But a 2018 study found that about one third of school psychologists were still using the discrepancy model to screen students for learning disabilities.

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 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 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 ...

Why do many educators want to move away from the discrepancy model for the determination of a specific learning disability?

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.

IQ/Achievement test and the discrepancy model and explaining the Independent Evaluation process

What is wrong with the discrepancy model?

Often referred to as patterns of strengths and weaknesses or by Odegard as “discrepancy 2.0,” this method continues to rely heavily on cognitive tests and still calls for significant gaps between ability and performance for a student to qualify as having a learning disability.

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 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.

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.

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.

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?

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

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.

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 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 discrepancy model of dyslexia?

The method for diagnosing dyslexia, known as the discrepancy model, was relatively straightforward: test a child's IQ and their reading age, and if there was a discrepancy between the two – average-to-high IQ, low literacy – that child was dyslexic.

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 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 does the discrepancy model determines whether or not a child should receive special education services based on what?

The discrepancy model is an approach used in special education to determine whether a student has a specific learning disability (SLD). This model compares a student's cognitive ability or IQ to their academic achievement in specific areas such as reading, writing, or math.

What are the applications of discrepancy theory?

Applications for discrepancy theory include: Numerical integration: Monte Carlo methods in high dimensions. Computational geometry: Divide-and-conquer algorithm. Image processing: Halftoning.

What is the severe discrepancy method?

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 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 IQ range for SLD?

A Specific Learning Disorder will refer to all those whose difficulties satisfy the DSM - 5, and ICD-10 criteria - of significant and persistent academic underachievement that begin during school, including that of having a measured IQ of 70 and above.

What are the models to determine SLD?

Current identification approaches can be classified into three broad models: (a) discrepancy approaches, (b) response-to-intervention (RTI) and problem solving approaches, and (c) the processing deficit approaches.

Are states free to prohibit discrepancy models from being used at all?

States are free to prohibit discrepancy models from being used at all. Statewide achievement tests could be considered to be examples of sweep screenings to assess academic performance levels. The 2006 federal regulation clarifies that child find and referral obligations do not include students with passing grades.
