There’s a lot of language development that happens during the school years.

Children with cochlear implants show delays learning that language.

Those delays are largest for phonologically based language functions, complex syntax, and writing.

During the School Years

• Provide ample opportunity to discover phonological structure

• Emphasize reading instruction

What can we do as a profession?Advocate for adequate and appropriate intervention

Expand training programs for professionals serving school-age children with hearing loss

Translational research on effective interventions
