A clear, balanced breakdown of ASHA's guidance, the controversy, and how to respond ethically in practice
ASHA’s position statement flatly warns against the Rapid Prompting Method and Spelling to Communicate. Yet for Andrea Palerino’s nonverbal daughter, a letterboard opened the door to academic coursework and testimony before the New York State Assembly.
That split between institutional caution and family testimony forces speech-language pathologists to weigh published evidence against the deeply personal outcomes they see in clinical practice. This is not simply a methodological dispute; it goes to the core of authorship, autonomy, and how we define trustworthy communication.
As the 2026 re-examination of these methods intensifies, the profession faces an uncomfortable gap between what the research can currently prove and what some autistic individuals and their families say they have achieved. For SLPs on IEP teams and in private practice, the pressure to take a side is mounting.
In 2018, the American Speech-Language-Hearing Association (ASHA) issued a formal position statement titled ASHA Warns Against Rapid Prompting Method or Spelling to Communicate.1 The statement advises speech-language pathologists (SLPs) against using Rapid Prompting Method (RPM) and Spelling to Communicate (S2C), two approaches that involve a facilitator supporting a non-speaking individual's hand, arm, or a letterboard during spelling tasks. The guidance does not apply to all forms of spelling instruction or to augmentative and alternative communication (AAC devices) used independently.
ASHA's position statement identifies five specific concerns about RPM and S2C:
ASHA reaffirmed these concerns in a 2026 letter to the Vermont legislature,2 stating that information obtained through RPM should not be assumed to be the communicator's own.
It is important to clarify the boundaries of ASHA's warning. The statement is not a blanket rejection of spelling as a communication tool. ASHA supports the use of letterboards and other AAC strategies when they enable independent expression. The concern is specific to approaches where a facilitator physically supports the person's hand or holds the letterboard in a way that may influence the message. ASHA's position statement does not prohibit speech-language pathologists from holding, stabilizing, or positioning an AAC device to ensure proper access, a distinction that sometimes creates confusion among practitioners and families.
Since its initial release, ASHA has refined its language to emphasize that it is not opposed to spelling or AAC, but only to methods that introduce unclear authorship. The core message, however, has stayed the same: RPM and S2C lack the scientific evidence needed to be considered valid, reliable tools in speech-language pathology practice. As highlighted in a July 2026 piece in Autism Spectrum News by Andrea Palerino, these nuances matter deeply to families and clinicians navigating the complex landscape of communication support.
As speech-language pathologists face growing demand for alternative communication methods, the debate over spelling-based approaches has become one of the most heated in the field. Understanding the distinctions between these methods is critical, because ASHA’s 2026 position statement groups several techniques under the umbrella of “spelling methodologies” and issues firm warnings. Below, we define each approach as described by ASHA, the International Association for Spelling as Communication (I-ASC), and other authoritative sources, and highlight how they diverge in practice.
FC carries decades of controversy, with multiple controlled studies demonstrating facilitator influence. While RPM and S2C proponents emphasize that they do not involve physical hand-over-hand support, ASHA places them in the same family because each method introduces another person into the message-production process. The central worry is that even non-physical support, such as holding a board, offering pacing cues, or providing verbal prompts, can shape the communication output, a significant concern for SLPs providing autism speech therapy.
I-ASC’s best-practice guidelines stress presuming competence, understanding cognitive-motor balance, and ensuring proper board positioning.2 However, ASHA’s position remains that until methods can reliably rule out facilitator influence, they cannot be recommended. The organization specifically notes that a simple way to reduce potential bias is to place the alphabet board on a table or mount instead of having an aide hold it.1 This distinction underscores the practical line between supported and independent communication.
In 1880, the Milan Conference banned sign language in schools, mandating oral-only instruction. Just as spelling methodologies face skepticism today, sign languages were dismissed for decades before being formally recognized as full languages, with the 2010 rejection of the Milan resolutions affirming their legitimacy.
In 2020, researchers Jaswal, Wayne, and Golino conducted an eye-tracking study with nine nonspeaking autistic adults who communicated using a letterboard. The participants, ranging in age from 15 to 26 and mostly male, had at least 2.25 years of experience with the method. Using head-mounted eye-tracking glasses, the team recorded gaze during naturalistic lessons at a specialized center. Each session involved an assistant reading a text in seven sections, after which participants answered one to six novel questions by pointing to letters on a board.
The findings were striking: participants consistently looked at a letter about half a second before their finger touched it. Their pointing speed averaged roughly one letter per second, with very few spelling errors. These timing and gaze patterns closely resembled those of fluent typists, suggesting that the individuals were actively selecting letters under their own control rather than being physically guided by the assistant.
Critics of spelling methodologies have long argued that the messages produced are actually generated by the facilitator through subtle, unconscious cues. The Jaswal study directly challenges this claim. The rapid eye fixations on letters prior to pointing are difficult to reconcile with an assistant manipulating the speller's hand. If the facilitator were driving the output, we would expect the speller's gaze to lag behind or drift, but the data show a proactive search for the next letter. Additionally, the low error rate and consistent speed point to a practiced, independent motor plan. While the study did not rule out all forms of influence, its authors argued that the gaze evidence is inconsistent with simple cueing.
Despite its intriguing results, the study has significant limitations. The sample size of just nine participants from a single center limits generalizability. The naturalistic setting, while ecologically valid, made it impossible to control for every potential cue. Skeptics point out that the assistant reading the text could have provided auditory or visual hints, and that unconscious facilitator movements might still escape detection by eye tracking.1 Crucially, no independent team has replicated these findings, and no subsequent systematic review has endorsed spelling-to-communicate as an evidence-based practice. ASHA's position statement draws on broader reviews that find insufficient evidence for Rapid Prompting Method and Spelling to Communicate. The evidence base remains fiercely contested, with families and some clinicians pointing to studies like Jaswal's as proof of concept, while ASHA and other professional bodies await more rigorous, controlled research.
SLPs walk a fine line between honoring families’ lived experiences and upholding evidence-based practice. The ASHA Code of Ethics requires you to fully inform families about the lack of evidence and risks of spelling methodologies, even when they passionately advocate for them. This creates genuine ethical tension.
ASHA's official guidance creates a noticeable double standard: it permits speech-language pathologists to hold or stabilize an augmentative and alternative communication (AAC) device, but the same type of physical support, holding a letterboard, is viewed as a red flag in rapid prompting method (RPM) and spelling to communicate.
ASHA's AAC Practice Portal explicitly states that SLPs may hold, stabilize, or position an AAC device to facilitate access.1 The association emphasizes that such support should be provided in collaboration with physical and occupational therapists, and ideally the device is placed on a stable surface or mounted rather than hand-held. The rationale is that these actions compensate for motor challenges without influencing the user's selection; the communication partner assists with positioning, not with pointing or choosing symbols.
In its position statement on RPM and spelling to communicate, ASHA warns that an alphabet board should be placed on a table or mount "instead of holding it in the air."2 The statement condemns RPM as lacking scientific support and FC as a discredited technique.2 While ASHA does not explicitly forbid all physical support during spelling, it treats hand-held letterboards as inherently vulnerable to facilitator influence, even though the reasoning closely mirrors the motor-support justification used for AAC.
The perceived double standard stems from contrasting ASHA's acceptance of positioning and mounting as legitimate access support with its rejection of hand-held boards as facilitator-contaminated. Critics, including the author of the Autism Spectrum News article, argue that both scenarios involve a communication partner providing motor scaffolding. Proponents of spelling methodologies point out that, like AAC, letterboard communication can be assessed through eye-tracking research and structured practice protocols, and that rejecting any touch-based support while allowing it for devices creates an inconsistency that confuses families and limits options for individuals with severe motor challenges. ASHA itself recommends interdisciplinary teams evaluate communication supports based on individual needs, a principle that some say should apply equally to all methods.
The conversation around spelling instruction for minimally verbal children has shifted considerably, with a growing body of research affirming that structured, phonics-based approaches can build real spelling skills. Moving beyond contested methods, speech-language pathologists now have a clearer picture of what actually works.
For nonspeaking learners, spelling development starts with the same foundational skills as for speaking children: phonological awareness, letter-sound knowledge, and print exposure. Research emphasizes explicit, systematic instruction in phonemic features, even for children who do not produce speech. Activities like sorting pictures by initial sound, using manipulatives to segment and blend phonemes, and engaging in word-building games with letter tiles or a touchscreen lay the groundwork. These practices do not require vocal responses, making them accessible through pointing, eye gaze, or AAC selection.
Several literacy programs have been successfully adapted for minimally verbal autistic children. The freely accessible ABRACADABRA web-based program, evaluated with children ages 5-11 with autism, improved foundational spelling when combined with AAC modeling and visual scaffolds.1 A modified Words Their Way intervention, implemented with five students with autism in grades 5-7, produced gains in taught words and moderate improvement for untaught words,2 and has been further adapted for an adolescent AAC user through symbol cards and switch access.3 While multisensory synthetic phonics approaches such as Orton-Gillingham-derived All About Spelling show promise,4 rigorous autism-specific trials remain limited. The underlying principles, structured, sequential, and multisensory, align well with adaptations using letter tiles, touchscreens, and AAC.
AAC for nonverbal autism is not just a communication tool; it is a literacy platform. SLPs can embed spelling instruction into AAC use by modeling words on the device during shared reading, encouraging invented spelling with feedback, and selecting apps that support phonics-based practice.7 Code-focused computer-assisted instruction, with four studies including autistic participants, has shown gains in spelling and allows for non-verbal responses.5 Techniques like cover-copy-compare, word boxes for phoneme-grapheme mapping, and matrix training for generative spelling all translate smoothly to AAC environments.6 What matters is that the learner independently selects letters or targets, without physical prompting that could mask the source of the communication.
Start by presuming competence and providing abundant literacy exposure. Incorporate picture-word pairing, a strategy highlighted in Autism Speaks' tips for teaching nonverbal children, to build sight-word recognition alongside phonics. Incorporate phonological awareness games into each session and offer multiple response modes: eye-gaze frames, keyboarding, or selecting from an array. When adapting programs like Words Their Way, break down sorts into smaller sets and allow for switch scanning or partner-assisted scanning. The goal is always genuine, independent authorship. By centering evidence-based literacy instruction, SLPs equip nonspeaking children with durable skills that open academic and social opportunities, without relying on unproven methods.
ASHA's official warning against the Rapid Prompting Method (RPM) and spelling to communicate (S2C) carries significant weight in school-based settings, where speech-language pathologists often serve as the communication experts on Individualized Education Program (IEP) teams. When a parent requests that a letterboard or similar spelling-based method be used with their child, the SLP's response is shaped not only by clinical judgment but also by the professional guidelines that districts look to when making decisions.
ASHA does not recommend RPM due to a lack of scientific validity, concerns over facilitator influence, and questions about who is truly authoring the messages. However, it explicitly states that it does not oppose spelling, letterboards, or augmentative and alternative communication (AAC) in general. Instead, its objection targets facilitator-dependent communication where another person may subtly or overtly guide the speller's hand or hold the board in a way that could introduce bias. This nuanced stance means that an IEP team cannot simply say "ASHA says no"; they must evaluate the specific implementation proposed, the level of facilitator involvement, and the available evidence for that particular student.
In 2026, the only known state-level legislative action touching on this issue was Vermont's Joint Resolution 9, which prompted ASHA to submit a formal letter on April 8, 2026, to the House Committee on Human Services.1 The letter reiterated that ASHA's concern is not with the alphabet board itself but with the potential for the facilitator to influence the message, framing the issue as one of authorship rather than motor support. Testimony continued during the week of April 6, and some legislators questioned whether ASHA should reconsider its position, but no contrary policy or law was enacted.2 Beyond Vermont, no other state education departments have issued formal guidance specific to spelling-based methods as of mid-2026.2
When a parent requests a spelling-based methodology in an IEP meeting, SLPs can take several steps to maintain both ethical integrity and collaborative relationships:
Ultimately, IEP teams must make individualized decisions, and while ASHA's position statement is not law, it functions as a strong professional touchstone that districts use to guide practice. SLPs who approach these conversations with clarity, compassion, and a commitment to authentic communication will be best positioned to serve both the student and the team.
The 2020 eye-tracking study shows that spellers look at each letter before pointing and exhibit timing patterns like fluent typists, but until these findings are replicated in larger, more diverse populations, the evidence remains too limited to settle the controversy.
Navigating the divide between ASHA’s evidence-based cautions and the lived experiences of families seeking communication options can be challenging. The list below offers starting points from both sides of the conversation, so you can review the science, policy positions, and the practical frameworks used by families and spelling practitioners.
