According to Google, 3 kinds of phonological processing appear to be needed for mastery of written language: phonological awareness, phonological memory, and rapid naming. 

Phonological awareness (measures an individual’s awareness and access to the phonological structure of oral language), phonological memory (measures an individual’s ability to code information phonologically for temporary storage in working or short-term memory, and rapid naming (measures the individual's efficient retrieval of phonological information from long-term or permanent memory, as well as the ability to execute a sequence of operations quickly and repeatedly). 

A deficit in one or more of these kinds of processes is viewed as the most common cause of learning disabilities and reading disabilities.  Perfect for Speech and Language Pathologist or School Psych or Educational Therapists who don't need the latest version of this comprehensive assessment tool.  Protocols (24 included) are normed for ages 7 to 24.
