The Evolution of Core Vocabulary Instruction
The concept of "core vocabulary" is foundational to AAC intervention. Unlike fringe vocabulary, which consists of words specific to a particular topic or environment (such as "hamburger" or "volcano"), core vocabulary comprises the small set of high-frequency words that account for approximately 80% of what individuals say on a daily basis. These words—such as "go," "more," "stop," "in," "out," and "that"—are versatile and can be used across multiple contexts, activities, and communication partners.
The initiative to curate monthly resources began as an effort to combat the common challenge of inconsistent AAC modeling. Research in speech-language pathology has long suggested that aided language stimulation—where communication partners model the use of AAC devices while speaking—is a primary driver of language acquisition. However, many educators and parents often struggle with knowing which words to target and how to plan activities that naturally incorporate these words. The "Year of Core Vocabulary" series was developed to bridge this gap, offering a structured, month-by-month roadmap that provides consistency and predictability in instruction.
Chronology of Development
The development of these resources has been a multi-year project involving various contributors. The chronology of the project highlights the expansion of the curriculum to meet the needs of different age groups:
- Initial Phase (The Foundation): The project launched with the "Year of Core Vocabulary Words," focusing on a manageable list of high-frequency words for each month. This phase established the efficacy of using monthly themes to guide instruction.
- Expansion (Building Capacity): Following the success of the initial list, a second set of resources was introduced to diversify the vocabulary and introduce new activity calendars. Key contributors, such as Rachael Langley, an AAC SLP and co-founder of Talking AAC, played a pivotal role in designing practical, classroom-ready activity calendars that integrated these words into daily routines.
- Specialized Curricula (The School Year Series): Recognizing that the needs of a preschooler differ significantly from those of a middle or high school student, the project expanded in 2020. The "School Year of Core Vocabulary Words" was launched, with guest contributions from Michaela Sullivan, Alisa Lego, and Beth Lytle. This series provided more sophisticated instructional strategies tailored to the academic environment.
- Secondary Education Focus (2023–2024): Most recently, the initiative expanded to include lessons specifically for older students. Developed by Michaela Sullivan and Lindsay Dougherty, this series addresses the communication needs of adolescent and teenage AAC users, focusing on vocabulary that is socially and academically relevant to their peer groups and transition goals.
Data-Driven Approaches to AAC Implementation
The emphasis on core vocabulary is not merely pedagogical preference; it is rooted in linguistic data. Studies on communication frequency consistently demonstrate that a small percentage of words are used with high frequency across settings. For an individual using AAC, gaining proficiency in this core set is essential for achieving communicative competence.
According to industry benchmarks, users who focus on core vocabulary demonstrate faster rates of acquisition compared to those who focus solely on specific noun-heavy vocabulary. The PrAACtical AAC resources provide quantitative support for this by organizing activities that target specific core words, allowing for repeated practice and generalization. By utilizing the February-specific resources, for instance, a therapist can track the frequency of word usage during structured activities, providing a baseline for monitoring progress throughout the month.
Official Perspectives and Expert Contributions
The project’s longevity is largely attributed to the collaborative nature of its development. Carole Zangari, the lead behind PrAACtical AAC, has consistently emphasized the importance of community-sourced expertise. The guest contributors—Sullivan, Lego, Lytle, and Dougherty—bring diverse clinical experiences that reflect the reality of working in various settings, from private practice to public school systems.
These contributors have noted that the primary hurdle in AAC implementation is not the technology itself, but the consistency of the human interaction surrounding the device. "The goal is to move from sporadic use to intentional, high-frequency modeling," an expert associated with the program noted. By providing pre-planned, age-appropriate materials, the project removes the burden of lesson planning from the practitioner, allowing them to focus on the quality of the interaction.
Impact on Educational Settings
The implementation of these monthly resources has had a measurable impact on classroom environments. In schools, the "School Year of Core Vocabulary" has helped create a universal language of communication. When teachers, aides, and SLPs all focus on the same set of core words, the student receives consistent reinforcement, which is critical for language learning.
Furthermore, the "Older Student Lessons" have addressed a significant gap in the field. Historically, many AAC resources were designed with a primary school focus. By pivoting toward age-appropriate, complex social scenarios for older students, the program has helped ensure that communication remains a priority for AAC users as they progress toward graduation and adulthood. This inclusion is vital, as it empowers older students to advocate for their needs, participate in academic discussions, and foster social relationships—all of which are facilitated by a strong core vocabulary.
Broader Implications for the Future of AAC
As we enter 2026, the continued relevance of these resources speaks to the enduring need for structured, accessible AAC support. The shift toward digital accessibility, including printable PDFs and cloud-based resources, has ensured that these materials can be utilized globally. The implications for the future are twofold:
- Standardization of Care: By providing a structured framework, these resources help move the field toward a more standardized approach to AAC instruction. This reduces the variability in the quality of service students receive, regardless of the individual practitioner’s level of experience.
- Parental and Family Engagement: A significant advantage of the PrAACtical AAC model is that the materials are designed to be accessible to families. By extending the classroom core word focus into the home environment, parents are empowered to become active partners in the communication process, which significantly improves long-term outcomes for AAC users.
Accessibility and Resource Access
For those seeking to utilize these materials, the PrAACtical AAC portal serves as a centralized hub. The resources are categorized by complexity and age, ensuring that a user can find content appropriate for a wide range of developmental stages. The February materials, in particular, include:
- Set 1 & 2 Resources: Targeted at early learners, focusing on foundational high-frequency words and basic sentence construction.
- School Year Resources: A middle-tier set of materials that bridge the gap between early language development and more complex academic communication.
- Older Student Lessons: Advanced resources that focus on pragmatics, social nuance, and academic vocabulary.
By maintaining these resources as public, open-access tools, the initiative ensures that financial barriers do not prevent individuals with complex communication needs from receiving high-quality, research-based intervention. As the AAC community continues to grow, the commitment to sharing, refining, and updating these materials remains a cornerstone of the professional effort to improve communication outcomes.
In conclusion, the February Year of Core Vocabulary Resources represent a decade of iterative improvement and collaborative expertise. By providing a clear, evidence-based roadmap for communication instruction, these materials continue to support the essential goal of giving every AAC user a robust, versatile, and functional vocabulary. Whether in a classroom, a therapy room, or at home, the systematic application of these core words remains one of the most effective strategies for fostering communicative independence.
