Comprehensive Test of Phonological Processing (utilized if Dyslexia is suspected)

The CTOPP-2 is a comprehensive instrument designed to assess phonological awareness, phonological memory, and rapid naming. People with deficits in one or more of these areas may have more difficulty reading than those who do not. The CTOPP-2 identifies individuals ages 4 through 24 who may benefit from instructional activities to enhance their phonological skills.

Gray Oral Reading Test (utilized if Dyslexia is suspected)

The GORT-5 provides an efficient and objective measure of ability and growth in oral reading and comprehension. When used in conjunction with other batteries, it is used to identify students with reading difficulties who may need more intensive or explicit instruction in basic reading skills and comprehension.
