Nineteen boys aged 6 through 8 years were pretested with the preliminary edition of the Sensory Integration and Praxis Tests (SIPT) (Ayres, 1984). They subsequently received 6 months of twice weekly occupational therapy with sensory integration intervention in a school setting and were then posttested with the preliminary edition of the SIPT. Significant improvement was seen in scores of grouped data on tests of praxis, somatovestibular functioning, and bilateral integration and sequencing. Individual improvement was visible in the Western Psychological Services ChromaGraphs of 17 of the 19 boys. Although preliminary, these findings suggest that the SIPT, unlike the Southern California Sensory Integration Tests (Ayres, 1972a), may be used to document improvement in children who have received occupational therapy with sensory integrative techniques.
