Dyslexia Assessment

The Tests of Dyslexia (TOD) Assessment includes an Early Assessment (ages 5-6) and a Comprehensive Assessment (ages 6-adult). The TOD identifies the risk and probability of dyslexia in individuals ages 5 to 89 years. The TOD also provides instruction and intervention recommendations based on assessment results. The assessments include 9-23 subtests (depending on the individual’s age and the need) to look diagnostically at the individual’s literacy profile. Individuals in grades K-1 will likely participate in fewer subtests, while those in grades 2 to adulthood will participate in more subtests.
