Please refer to each test manual to learn about specific test normative samples.  We conduct nationwide standardization projects. Each normative sample usually consists of 1000+ examinees (typically developing), stratified to match the most recent U.S. Census data on gender, race/ethnicity, and region.

Our rating scales can be easily completed online. They include videos of questions as well as online rating forms that are scored automatically online. Our articulation test can be administered from a computer/laptop or tablet. The test is composed of short pre-recorded video segments, which contain 45-55 target words. Individuals are asked to label or name specific items in the videos. The clinician listens carefully to the production of each word and records any distortion, substitution, omission, or lisp of the targeted sounds. The clinician also makes note of any phonological process, such as stopping, fronting, initial consonant deletion, or gliding. The assessment yields a raw score, standard score, percentile rank, interpretation value, and test-age equivalent. The clinician can complete the protocol online or print the PDF to have a hardcopy, and then transfer the results to the “Raw Score” page on the assessment website. The raw scores can then be converted automatically to standard scores, which will also reveal a percentile rank.

All standardization project procedures were implemented in compliance with the Standards for Educational and Psychological Testing (American Educational Research Association, American Psychological Association, & National Council on Measurement in Education [AERA, APA, and NCME], 2014). Additionally, all standardization project procedures were reviewed and approved by IntegReview IRB (Advarra), an accredited and certified independent institutional review board, which is organized and operates in compliance with the US federal regulations (including, but not limited to 21 CFR Parts 50 and 56, and 45 CFR Part 46), various guidelines as applicable (both domestic and international, including but not limited to OHRP, FDA, EPA, ICH GCP as specific to IRB review, Canadian Food and Drug Regulations, the Tri-Council Policy Statement 2, and CIOMS), and the ethical principles underlying the involvement of human subjects in research (including The Belmont Report, Nuremberg Code, Declaration of Helsinki).

Our tests are developed by the Lavi Institute under the guidance of Adriana Lavi, PhD, CCC-SLP (author of the Clinical Assessment of Pragmatics (CAPs) test, the IMPACT rating scales and many more.
