About the LSL Specialist Certification

The AG Bell Academy for Listening and Spoken Language offers Listening and Spoken Language Specialist (LSL Specialist) certification to qualified professionals who meet high standards of education and professionalism in the field of listening and spoken language. After meeting mentorship requirements and passing the LSL Specialist certification exam, professionals can earn certification as either a LSL Specialist Certified Auditory-Verbal Therapist (LSLS Cert. AVT) or LSL Specialist Certified Auditory-Verbal Educator (LSLS Cert. AVEd).

Routes to LSLS Certification

Professionals who wish to pursue certification typically find they are more eligible to pursue one route to certification over another based on their particular work environment(s).

The Listening and Spoken Language Specialist Certified Auditory-Verbal Therapist (LSLS Cert. AVT) designation is usually pursued by professionals who are able to complete the required clock hours providing individual auditory-verbal therapy with children and their parent(s) or caregiver(s).

The Listening and Spoken Language Specialist Certified Auditory-Verbal Educator (LSLS Cert. AVEd) designation is usually pursued by professionals who are able to complete the required clock hours providing auditory-verbal education services in a group environment in which a parent may or may not be present.

Some professionals may work in an environment that lends itself to pursuing either designation. Questions regarding routes to certification should be directed to the Academy.
