The Rossetti Infant-Toddler Language Scale




World-renowned 0-3 development scale!

The Rossetti Infant-Toddler Language Scale is designed to provide the clinician with a comprehensive, easy-to-administer, and relevant tool to assess the preverbal and verbal aspects of communication and interaction in the young child.

The Rossetti Infant-Toddler Language Scale is a criterion-referenced instrument that assesses Interaction-Attachment, Pragmatics, Gesture, Play, Language Comprehension, and Language Expression.

Behaviors can be directly elicited from the child, directly observed, or reported by parent or caregiver to credit the child's performance. All carry equal weight when scoring the scale. Results reflect the child's mastery of skills in each of the areas assessed at three-month intervals across developmental domains tested.

The test items guide you in directing and structuring observations in order to monitor the child's progress in language developmental areas. The items are based on a compilation of author observation and descriptions from developmental hierarchies and behaviors recognized and used by leading authorities in the field of infant-toddler assessment. Only items considered discriminating and representative of a skill at an age were included.

Severity rating guidelines help you interpret the results and confidently communicate the severity of the child's delay.
