Identifying discrepancies in data is simple. You compare two data sets for the same period of time and look for numbers that don't match up.

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.

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 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 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.

What is the rating scale for learning disabilities?

The seven subscales representing the characteristics of learning disability are difficulties in performance in listening, thinking, speaking, reading, writing, spelling, or math. The items on the LDES are rated on the following 3-point scale: 1 = Rarely or never; 2 = Inconsistently; 3 = All or most of the time.

What is the severe discrepancy formula?

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 method of SLD?

The discrepancy model assumes that if a student has a significant difference between their expected achievement based on their cognitive ability and their actual academic achievement, then they may have a specific learning disability.
