The Provence Profile



  • Achieves greater depth in the essential psychosocial developmental domains than other measures, employs naturalistic observation, and incorporates parent reports of the child’s development.


  • Is Criterion Referenced


  • Builds a graphic portrait of the child’s competencies and concerns by evaluating eight developmental domains.


  • Features the traditional domains that assess developmental skills: gross motor, fine motor, cognition, language/communication, and self-help/adaptive plus psychosocial skills in the relationships to persons, emotions and feeling states, and coping developmental domains.


  • Includes the Developmental and Behavioral Concerns List with notation of potential ‘red flags’ in psychosocial areas that may need further evaluation.


  • Provides Guidelines for percentage delay calculation.



Service Plan


The IDA findings result in a descriptive summary of developmental competencies that includes a performance age range in each domain resulting in a Service Plan.





IDA forges partnerships among professionals for gathering and integrating information from multiple sources integral to the assessment process thereby eliminating duplication of effort, information, and fragmentation. The IDA results in an efficient and informed Service Plan with referral recommendation(s).
