The Communication Complexity Scale (CCS) is a 12-point scale that can be used to describe how a student with minimally verbal skills communicates. The term “minimal verbal skills” is used to describe expressive communication that includes preintentional behaviors (such as gestures, eye gaze, and non-speech vocalizations), intentional communication acts and some symbolic communication including single words spoken, signed or selected in a graphic mode. There is no lower limit. The scale describes the complexity of specific communication behaviors observed, and summary scores can characterize the overall communication level across the observation. The CCS can be used to measure early communication in scripted and naturalistic (e.g., classroom and parent/child interactions) settings. 

CCS Trainings Are Available and Include

-In-person or virtual trainings typically require 1 and 1/2 days.

-Eleven online modules that are viewed ahead of the in-person or virtual training (approximately 9 hours to complete).

-An additional 7 modules on coding in naturalistic settings (approximately 3 hours to complete).

-Follow up training activities required for becoming research reliable in administration of the scripted play assessment or CCS scoring (additional cost).
