​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.

​The TOD-E is appropriate for pre-readers or emerging readers and is comprised of six tests. Together with the three tests from TOD-S, the TOD-E provides index scores for determining the probability that the individual has dyslexia. The nine total tests provide further information about the skills relevant to dyslexia.

​Tests of Dyslexia - Screener can be used with individuals in kindergarten through adulthood and is composed of three tests which screen for the risk of dyslexia. TOD-S provides a Dyslexia Risk Index (DRI) which is considered an estimate of dyslexia risk.
