The ITPA differs in many ways from the IDEAL MODEL.
From the results of the test a teacher can determine the integrity of the modalities for learning, or the processes that may be significantly at fault.
Hence, academically, new information can be provided to the child through the modality that is functioning; and remedial work can be provided to strengthen the faulty language processes of the weak modality.
Still, there are many differences in the structure of the ITPA from our ideal model. For example, there are only two modalities tested instead of three.
The Visual Modality is tested only at the conceptual level; while the auditory modality is tested only at the symbolic level.
The responses of the pupil to the stimuli in the auditory receptive and inner tasks are more complex than would be allowed in our ideal model.
