Tests of Dyslexia -Comprehensive

​The TOD-C provides a comprehensive dyslexia assessment for individuals in early elementary school through adulthood. Together with two of the tests from TOD-S, and six from the TOD-C are combined to create the Dyslexia Diagnostic Index (DDI). The DDI is the primary score in the TOD-C for determining the probability that the individual has dyslexia.
 
An additional 14 tests allow for further assessment of skills related to dyslexia yielding additional composite scores. These domains include reading and spelling, linguistic processing, and vocabulary and reasoning.
