Elevate your speech therapy practice with the Articulation Assessment Toolkit Plus (AAT Plus)—the most comprehensive, dynamic, and intuitive criterion-referenced articulation assessment designed specifically for Speech-Language Pathologists. Whether you are determining baselines, monitoring progress, or writing highly targeted IEP goals, the AAT Plus transforms complex speech sound data into clear, actionable clinical insights. Moving far beyond simple raw scores, this tool provides a multi-dimensional analysis of your student's speech sound production, right from your iPad. KEY CLINICAL FEATURES Comprehensive Assessment Modules Quick Consonant Screener: Rapidly assess all English consonants in initial, medial, and final positions. Full Assessment: Evaluate all consonants plus a comprehensive Vowels Analysis (Singletons, Diphthongs, Tongue Advancement/Height, and Lip Rounding). Specialized R-Screener: Tackle the complex /r/ phoneme with a dedicated module targeting prevocalic /r/, vocalic /r/ (ar, er, ear, etc.), and R-blends. Features specialized visual badging for distortions ("dis") and gliding ("gl"). Sentence Screener: Evaluate connected speech to identify coarticulation errors and patterns that only appear in continuous dialogue. Advanced Analytics Dashboard Instantly view detailed color-coded breakdowns of your student's speech sound breakdown across six critical categories: Position in Word: Initial, Medial, and Final. Manner of Articulation: Fricatives, Plosives, Nasals, Glides, etc. Place of Articulation: Bilabial, Alveolar, Velar, Palatal, etc. Voicing Features: Differentiates voiced vs. voiceless consonant accuracy. Word-Level Breakdown: A complete phonetic transcript of target words, highlighted errors, and clinical notes. Error Types & Phonological Processes: Automatically identifies active error patterns (e.g., Final Consonant Deletion, Cluster Reduction) and provides built-in developmental suppression ages. Dynamic Stimulability Testing Automatically imports all missed targets from your assessment into an interactive stimulability dashboard. Test isolated sounds and specific word positions with built-in auditory/visual modeling prompts. Watch target statuses update in real-time (Untested, Stimulable, Not Stimulable) to effortlessly select your next therapy targets. Developmental Sound Profile Instantly overlay your student's assessment data onto standard developmental acquisition norms (adapted from Sander, 1972). Perfect for parent consultations to visually demonstrate whether an error is developmentally appropriate or requires intervention. Professional Reporting & Exporting Generate beautiful, multi-page PDF clinical reports with a single tap. Capture subjective Intelligibility Ratings (Single Word & Conversational) via intuitive sliders. Add custom clinical recommendations directly to the final report. Seamlessly share via Apple AirPrint, Email, or export directly to the Smarty Ears Therapy Report Center (TRC). Why SLPs Love AAT Plus: While standardized tests are required for initial eligibility, the AAT Plus is your essential companion for functional treatment planning. Because it is a criterion-referenced tool, you can use it continuously for progress monitoring, dynamic assessment, and baselining without the validity restrictions of standardized tests. Empower your clinical decision-making and streamline your report writing with the AAT Plus!
