LinguiSystems Articulation Test Normative Update (LAT-NU)
Assesses individuals aged 3-21 who have abnormal articulation patterns. Screens for apraxia of speech, assesses consonant sounds and can be used to monitor progress.
Easy to administer, score and interpret, yet provides a thorough examination of all sounds/blends by presenting several sounds more than once in the same position.

Identifies children and young people with abnormal articulation patterns, ensuring a thorough assessment of sounds and blends by presenting several sounds more than once in the same position. All positions at the word level are tested.
This assessment tool allows examiners to rate the severity of the speech-sound disorder, rate the intelligibility of speech and evaluate stimulability. Also allows examiners to screen for apraxia of speech that impairs precision and consistency of speech.
Provides a comprehensive articulation proficiency score which represents an individual's overall speech sound ability. The record booklet provides space to record speech-sound errors by substitution, omission or distortion.
LAT-NU can screen for apraxia via evaluation of sequential productions of twelve multi-syllabic words. Intelligibility and stimulability can also be assessed. Rating is by noting the type and frequency of errors in a picture description task. Stimulability is assessed immediately after incorrect production occurs and determines if the individual is able to imitate a correct production.
Record booklets have a two-page summary allowing facilitators to visually analyse speech errors by word location, type and stimulability. All phonemes tested in the LAT-NU are included in the Speech Sound Error Analysis section.
The examiner's manual explains the assessment tool's theoretical and research-based foundation, item development, standardisation, administration and scoring procedures, normative tables and guidelines for using the test resources. Reliability and validity studies were conducted with typically developing students and students who had previously been diagnosed with an articulation disorder.
The average coefficient alpha is .92 for the Articulation Proficiency Score. New validity studies demonstrate the test’s ability to differentiate students with an articulation disorder from typically developing students. The results demonstrate that an Articulation Proficiency cutoff score of 94 resulted in a sensitivity of .77, a specificity of .85, and a receiver operating characteristic/area under the curve of .89.
Includes: Examiner's Manual, Picture Book, 25 Examiner Record Booklets in a storage box. (2018)

We can also bring in via air freight which will take around 1-2 weeks at an additional cost that will vary according to weight, volume etc. Please contact our sales team if you would like to obtain an air freight quote. Any products ordered in this manner are non-returnable.
(From 1st June 2019) To purchase this resource, please download our Assessment Tool Purchase & Agreement Form or contact our sales team if you would like this emailed or sent in the post to you. We must maintain proper test security to protect professionals and end users, and therefore it is essential for us, as distributors, to prevent the sale or disclosure of tests and assessments to people who are not trained in their use.
