The IDA is a comprehensive holistic developmental assessment that results in an Individualized Family Service Plan (IFSP). See our Frequently Asked Questions to learn more.


The IDA is a set of processes and procedures that include the Provence Profile, a measure with eight developmental domains.  The IDA achieves greater depth in the essential psycho-social domains compared with other instruments.  It employs naturalistic observation and incorporates parent reports of the child’s development. The result is a descriptive summary of the child’s developmental competencies that includes a performance age range.


The IDA Institute provides IDA Training through Online or On-site seminars and a range of consultation options.
