AAC Evaluation Report
Generated by EvAAL — Evaluating Adaptive & Assistive Learning
Assessment Summary
Jordan Reyes is an 8-year-old student in 2nd grade at Riverside Elementary School referred by the IEP team for an AAC evaluation to determine the most appropriate augmentative and alternative communication system to support functional communication across school settings. Jordan presents with a primary eligibility of Autism Spectrum Disorder with limited verbal output, typically using 1–2 word approximations to communicate wants and needs. The EvAAL AAC battery was administered across one session on July 17, 2026. Jordan was engaged throughout the session and demonstrated clear motivational responses to preferred symbol sets.
Evaluation results indicate that Jordan demonstrates reliable direct touch access with no need for switch scanning at this time. Symbolic representation performance indicates an optimal display of 12 symbols per page. Categorization skills are emerging and support the use of a folder-based vocabulary organization. The Device Trial revealed strong engagement with Proloquo2Go, which Jordan independently navigated to request preferred items on 4 out of 5 opportunities. Based on these findings, a robust, core-vocabulary-based AAC system with a 12-symbol-per-page display is recommended.
Subtest Results Summary

Access Methods Performance
Jordan demonstrated reliable direct touch selection across grid targets. Fitts's Law grid performance was consistent at the 12-icon density. Switch scanning was trialed but is not indicated — direct selection is the recommended access method. No alternative input device is required at this time.
Symbolic Representation & Grid Density
Performance across symbol grid sizes confirmed that Jordan navigates most accurately at 12 symbols per page. Accuracy dropped to 54% at the 20-symbol display, indicating that dense layouts should be avoided in the recommended AAC system. Symbol sequencing at 70% suggests emerging understanding of multi-symbol utterances — vocabulary organization should support 2–3 word combinations as an immediate goal.
Device Trial Results
Proloquo2Go
Jordan independently navigated to the "want" core word and selected preferred items on 4 out of 5 opportunities with minimal prompting. Responded positively to the symbol style and page layout.
TouchChat HD
Jordan required full physical prompting during most navigation tasks. Symbol style and page density appeared less intuitive. Did not independently request using this device.
AAC Recommendations
Proloquo2Go — Core Vocabulary Setup
Implement Proloquo2Go with a 12-symbol-per-page layout using a core + fringe vocabulary organization. Begin with basic wants/needs, social closers, and core action words (want, more, stop, go, help). Gradually expand vocabulary pages as Jordan's navigation skills grow.
Primary AAC SystemDirect Touch Access
No mounting system, stylus, or switch interface is required at this time. Standard iPad with protective case and kickstand is sufficient. Re-evaluate access method in 12 months or if motor changes are observed.
Device AccessAided Language Stimulation (ALS)
All communication partners should model AAC use by pointing to symbols on a matching display during natural interactions throughout the day — not just during therapy. A team training session on ALS is strongly recommended prior to device implementation.
Communication Strategy2–3 Word Combination Goals
Based on syntactic performance (70%), Jordan is ready to target 2–3 word combinations: "want + [item]", "more + [activity]", "I + want + [item]". Vocabulary should be organized to make these combinations easy to construct across all communication partners.
Language GoalsSuggested IEP Goal Language
Given access to Proloquo2Go and a trained communication partner, Jordan will independently navigate to and activate a 2-symbol combination (e.g., "want + cookie") to make a request across 3 different settings, with 80% accuracy over 4 consecutive data collection sessions.
Given a modeled prompt and access to Proloquo2Go, Jordan will use a social closer ("bye," "all done," "no thank you") independently in 4 out of 5 naturally occurring opportunities per day, as measured by frequency data collected by the classroom team over 6 weeks.
