IDA Research
Scoring
Scores that can be generated by using the IDA include percentage delay.
The eight developmental domains of the IDA can be hand-scored. Complete instructions are provided in the IDA Administration Manual.

Interpretation
Methods to evaluate the results obtained from the Infant-Toddler Developmental Assessment are described in the IDA Administration Manual.
It is important to note the differences between the performance age obtained by the IDA and an age equivalent. Unlike the Provence Profile performance age ranges, age equivalents provide no information about which items were passed or missed, nor do they provide information about whether a given combination of passes and misses are at all typical of children at the indicated age. The performance age that is obtained by using the Provence Profile is obtained by applying carefully established scoring criteria for age-level item sets, whereas an age equivalent is obtained by looking up the age level for which the child’s raw score was the average in a norming sample.
