The LinguiSystems Articulation Test NU(LAT:NU) App for iPad can be used only by certified/licensed speech-language pathologists to assess articulation disorders. Paraprofessionals, support personnel or guardians cannot adequately administer, interpret, and score the test.
The app includes a digital version of the complete ExaminerÃ¢â‚¬â„¢s Manual and the five picture plates needed for administration, as well as a screen for automatically calculating standard score, age equivalency, and percentile rank based on the studentÃ¢â‚¬â„¢s chronological age and raw score. Test items are administered by touching the screen to visually isolate target words within the picture scenes. Original, printed LAT:NU test forms must be used to administer this test to meet the requirement of having original documentation in the client's/student's permanent folder.
Please Note: Reliability studies to confirm that administrating the test via app maintains the validity of the LAT:NU print version are in process and will be concluded and reported in early 2013. Subjects ages 3.0Ã¢â‚¬â€œ8.11 are included in this study.
The LAT:NU App is designed to identify children and young adults with abnormal articulation patterns. It ensures a thorough examination of all sounds and blends by presenting several sounds more than one time in the same position. All positions at the word level are tested. The vocalic /r/ is tested in multiple contexts.
Test results, in combination with the stimulability and Childhood Apraxia of Speech Screening included with the LAT:NU App, allow the SLP to make appropriate recommendations regarding type and length of service. The assessment can be completed in about 15 minutes.
The LAT:NU App can also be used to measure progress in therapy.
