The Infant-Toddler Developmental Assessment–Second Edition (IDA-2) is a comprehensive, multidisciplinary, family-centered six-phase process designed to identify children birth to 3 years of age who are developmentally at risk. The IDA-2 includes the Provence Birth-to-Three Developmental Profile, a criterion-referenced measure of development in eight areas: (1) gross motor, (2) fine motor, (3) relationship to inanimate objects, (4) language/communication, (5) self-help, (6) relationship to persons, (7) emotions and feeling states, and (8) coping behavior.
IDA-2's team-based approach helps determine the need for monitoring, consultation, intervention, or other services for the child and family and may be used to develop an initial Individualized Family Service Plan (IFSP). The assessment process takes into account the complexity and interdependence of health, family, and emotional/social factors that influence a child's development.
IDA-2 has six phases, the procedures for which are explained step-by-step:
Scoring and Interpretation
The IDA-2 is criterion-referenced. Throughout the IDA-2 process, practitioners gather information from multiple sources, integrate that information in a meaningful way, and create a plan of action. Duplication of effort and information is eliminated. This saves time and money, reduces the stress created by more fragmented approaches, and yields more complete information. The IDA-2 process leads to efficient, informed decisions.
IDA-2 meets the assessment criteria required by IDEA and is consistent with the National Task Force on Screening and Assessment of the National Early Childhood Technical Assistance System (NECTAS) guidelines.
Reliability coefficients for the Provence Profile domain scores are generally quite high, ranging from .90 to .96 for ages 1 to 18 months and .78 to .96 for ages 19 to 36 months. Inter-rater reliabilities range from .91 to .95 for seven of the eight domains and .81 for the remaining domain.
