“Who qualifies for an SGD?” If you’ve asked yourself that question, you’re not alone. It’s one of the most common questions SLPs face, and the answer is rarely a simple yes or no.
SGD candidacy isn’t a single checkbox. It’s a process: screening for functional communication needs, determining whether current supports are meeting the individual’s needs, and documenting your findings in a way that supports next steps. That’s exactly what this guide is designed to help you do. It includes a downloadable SGD Device Screener you can start using with your caseload this week, along with documentation tips and sample language for your evaluation reports.
What “Qualifies” Means in Practice and Why It’s Often Confusing
One of the biggest sources of confusion around SGDs is understanding the difference between candidacy and funding approval. These are two separate things, and knowing the difference is key.
Candidacy vs. Funding and Coverage Criteria
As an SLP, you determine candidacy based on the individual’s communication needs, functional limitations, and response to current supports. The payer (Medicaid, private insurance, school district) determines funding approval based on their own documentation requirements. Some payers require a formal physician face-to-face visit, as outlined in ASHA’s Medicare SGD coverage policy overview. Others may require device trial data.. The good news? There are key documentation pieces you can control: thorough evaluation data, documented response to current supports, usage observations, and a clearly written rationale.
When to Consider an SGD Evaluation
Even though specific criteria differ by payer, certain signs consistently point toward the need for an SGD evaluation. You might notice the person struggles to participate in daily activities, experiences frequent communication breakdowns, has a reduced ability to express a range of communication functions, and evidence that current AAC supports aren’t meeting the individual’s needs. When you’re seeing these patterns, it’s worth digging deeper.
SGD, AAC, and “Speech Device” Terminology
Using accurate terminology in your reports can make a real difference in how payers interpret your recommendations.
Where SGDs Fit Within AAC
AAC encompasses all the tools and strategies that support communication, from low-tech picture boards to mid-tech devices to high-tech speech generating devices with dynamic output. SGDs fall within the high-tech category and are classified as durable medical equipment (DME) by most payers. For a deeper look, check out How High-Tech AAC Devices Transform Lives on the QuickTalker Freestyle blog.
Why Terminology Matters for Documentation
Payers look for specific language like “speech-generating device” and HCPCS codes such as E2510 when reviewing claims. A helpful rule of thumb: use “speech-generating device” or “SGD” when you’re referring to the actual equipment, and “AAC” when you’re talking about the broader range of communication support.
The SGD Screener: What It Is and When to Use It
Here’s what to expect from the downloadable screener and how it fits into the bigger picture.
What It Is
The SGD Screener is a one-page tool that helps you identify potential SGD candidates and structure your next steps. It covers six core areas of functional communication and takes about two to five minutes to complete. Think of it as a way to organize what you’re already observing into a consistent framework that supports team communication and documentation planning. It is designed to help you decide whether a full AAC evaluation is the right next step and gives you a head start on organizing the data you’ll need.
When to Use It
The screener works best at natural decision points: when reviewing new referrals, during caseload reviews, pre-evaluation planning, or team conversations (MTSS, IEP, team staffing). It also serves as a documentation tool to organize your findings into evaluation-ready language.
How to Use the Screener in Your Workflow (2 to 5 Minutes)
The screener is designed to fit into what you’re already doing, not add another layer of paperwork.
Recommended Use Points
Try using the screener at decision points you’re already working through: intake and referral review, pre-evaluation conversations with families or team members, MTSS or IEP case reviews, and team consultations. In each setting, the screener gives everyone a shared starting point and keeps conversation focused on functional communication data.
What to Have on Hand
Gather whatever you have available: therapy notes, language sample data, teacher or team input, intelligibility observations, and participation concerns from caregivers or staff. You don’t need all of this to get started. Even partial data will help you identify gaps and plan next steps.
Screener Walkthrough: What Each Item Tells You
The following sections walk through each of the six items on the SGD Device Screener. For each item, you’ll find why it matters, what to document, and what a “Yes” suggests for next steps.
1. History of Spoken Language Development Difficulties (Despite Intervention and Modeling)
Why it matters: Limited progress in spoken language development despite consistent intervention is one of the strongest indicators that an individual may benefit from a high-tech speech system. This applies when spoken language has plateaued or where generalization has been minimal.
What to document:
- Response to intervention over time, including duration and intensity of services
- Patterns of plateau or limited generalization to functional settings
- Functional spoken communication output, such as types of communicative functions expressed through speech alone
What a “Yes” suggests: Move forward with a comprehensive AAC/SGD evaluation to assess whether a high-tech speech generating device could give the person more ways to express themselves or could expand communicative functions beyond what spoken language alone has achieved.
2. Meeting Needs and Wants
Why it matters: Functional communication is about whether someone can express their needs, wants, preferences, and feelings in daily life. When an individual consistently struggles to communicate basics like hunger, pain, or refusal, it limits their ability to participate and be understood.
What to document:
- Communication functions currently achieved and those that remain unmet
- Frequency and context of breakdowns related to unmet needs
- How the individual attempts to communicate (gesture, vocalization, behavior, existing AAC) and whether attempts are understood
What a “Yes” suggests: Target specific functional outcomes in your evaluation, with device usage observation data focused on expressing needs and wants with greater success.
3. Intelligibility of Speech
Why it matters: When partners regularly can’t understand what someone is saying, the individual may reduce communication attempts, lean on familiar interpreters, or withdraw from interactions. This limits participation across school, social, and community settings.
What to document:
- Speech samples in structured and spontaneous contexts
- Intelligibility estimates with familiar and unfamiliar listeners
- Degree of listener dependence and impact on participation
What a “Yes” suggests: Consider AAC supports to reduce breakdowns and increase independence across partners and settings. See Presume Competence: 5 Key Strategies for Engaging AAC Users for more.
4. Frustration and Communication Breakdowns
Why it matters: Frequent breakdowns reduce willingness to initiate communication, limit participation, and can lead to behaviors that are often misinterpreted. Documenting them shows the real-world impact of insufficient communication support.
What to document:
- Breakdown frequency, context, and partners involved
- Type of breakdown (not understood, can’t express message, limited vocabulary)
- Repair attempts and whether they succeed
- What the individual was trying to communicate and what happened when it didn’t work
What a “Yes” suggests: Device usage observations should target breakdown reduction, improved repairs, and increased initiations.
5. Communication Across Environments
Why it matters: Communication doesn’t just happen in the therapy room. If it only works in one setting or with one partner, overall participation and independence are limited.
What to document:
- Where and with whom the person communicates successfully (a simple chart or matrix works well)
- Participation barriers in specific settings
- Differences between environments (e.g., effective at home but not at school)
What a “Yes” suggests: Device observations should happen across multiple environments with different partners, and implementation planning should be a core part of the evaluation. The Getting Started with High-Tech AAC: SLP Beginner Guide offers practical guidance.
6. Current Use of Low-Tech or Mid-Tech Solutions
Why it matters: Existing AAC supports are data, not disqualifiers. Multimodal communication is expected and beneficial. This item asks whether current tools are truly meeting the individual’s communication demands or whether gaps remain.
What to document:
- What AAC supports are in place and how they’re being used
- Specific limitations: restricted vocabulary, reduced ability to generate novel messages, lack of portability, or access barriers
- Situations where the current tool can’t keep up with the individual’s needs
What a “Yes” suggests: Look into what an SGD offers that the current system doesn’t: expanded vocabulary, dynamic message generation, symbol prediction, portability, and more.
Interpreting Screener Results: A Clear Decision Pathway
The screener isn’t a scoring tool with rigid cutoffs, but the pattern of responses gives you practical guidance for determining when a SGD may be beneficial.
If 0 “Yes” Responses
Current supports appear to be meeting functional needs. Document your findings, set a monitoring timeline (e.g., re-screen at the next IEP review or quarterly caseload review), and note what would indicate a re-screening.
If 1 to 2 “Yes” Responses
Look into AAC evaluation questions and begin structured device observations in the areas the screener flagged. This is also a good time to start conversations with the team and family about AAC as a support option.
If 3 or More “Yes” Responses
Move forward with a comprehensive AAC/SGD evaluation. The screener data gives you a head start on structuring that evaluation, including hands-on device trials, real-world usage observations, and documentation of functional outcomes.
A Simple If/Then Framework for Your Notes
If functional communication limitations appear across multiple screener areas, then a comprehensive AAC/SGD evaluation is the best next step.
If emerging concerns appear in one or two areas, then targeted data collection and structured observations are recommended.
If current supports are meeting needs, then document current status, set a monitoring timeline, and define re-screening criteria.
Next Steps After Completing the Screener: Building Your Evaluation Plan
If the screener identifies communication gaps or limitations, the next step is a comprehensive AAC evaluation.
Planning Your Device Usage Observations
Build a structured observation plan that includes:
- Clear communication goals for the observation period
- Which communication partners will be involved
- The environments where the device will be used
- A data collection plan and defined success criteria
What to Measure
Focus on outcomes that show real functional communication change:
- Independence: Less reliance on partners to communicate their messages
- Rate: Communicative acts per session or time period
- Communication Functions: Requesting, commenting, protesting, asking questions, sharing information
- Breakdowns: Frequency decreasing, repairs more successful
- Generalization: Communication transferring across environments and partners
What to Consider During the Evaluation
As you complete the evaluation, think through key areas such as:
- Access method (direct selection, switch scanning, eye gaze)
- Vocabulary organization and representation needs
- Portability and durability requirements
- Level of partner support available

Documentation Tips: Turning Your Data into Medical-Necessity-Ready Language
Strong documentation connects your evaluation findings to the individual’s functional needs. The ASHA Practice Portal on AAC and the ASHA medical necessity resource page are great foundational resources. Below are tips tailored to this screener workflow.
What to Include in Your Evaluation
Your evaluation report should address these four areas, each of which maps to common payer requirements:
- The functional impact of the communication disorder on daily participation
- The specific participation barriers the individual experiences
- The limitations of current communication methods and supports
- The outcomes observed during device usage observations
Documentation Checklist
Make sure your evaluation report covers:
- Baseline communication profile, including current methods and their effectiveness
- Environments affected, with specific examples
- Communication partners affected (familiar and unfamiliar)
- Frequency and impact of breakdowns, supported by data
- Summary of device usage observations: device tested, duration, settings, and outcomes
- Rationale for recommended features and device type
Sample Language for Evaluation Reports
Adapt these practice-ready, non-payer-specific statements to fit your evaluations:
“[Name] presents with a communication disorder that significantly limits their ability to express needs, wants, and ideas across daily environments. Current communication methods, including [describe current supports], are insufficient to meet their functional communication demands as evidenced by [cite specific data].”
“During structured device usage observations with [device name], [Name] demonstrated [specific measurable outcomes, e.g., increased communication initiations, reduced breakdowns, expanded range of communication functions]. These outcomes support the medical necessity of a speech-generating device to address documented participation restrictions.”
“A speech-generating device with [specific features, e.g., dynamic display, symbol-based vocabulary, direct selection access] is recommended to support [Name] in achieving functional communication across [environments]. Current low-tech and mid-tech supports do not provide [specific limitations, e.g., sufficient vocabulary, message generation flexibility, portability for community access].”

Frequently Asked Questions
Does this Screener Guarantee Coverage?
No. The screener identifies candidates for further evaluation. Coverage is determined by the payer based on their documentation and eligibility requirements.
What’s the Difference Between an AAC Evaluation and an SGD Evaluation?
An AAC evaluation considers the full continuum of communication supports. An SGD evaluation is a focused piece that specifically assesses the need for a speech-generating device, includes device usage observations, and produces documentation supporting a device recommendation. In practice, these are often done together.
Do Individuals Need Specific Cognitive Skills to Benefit from an SGD?
No. There are no cognitive prerequisites for determining who qualifies for an SGD. Research consistently shows that individuals across a wide range of cognitive profiles benefit when the device is appropriately matched and adequate support is provided. For more, see Why Speech-Generating Devices Should Be Accessible to All.
How Do I Justify an SGD When Low-Tech AAC Is Already in Place?
Document the specific limitations of the current system: insufficient vocabulary, inability to generate novel messages, limited portability, access barriers, or slower communication rate. Your data from the evaluation directly supports this argument.
What Role Do Device Usage Observations Play in Documentation?
They provide the data showing whether the individual benefits from the device in real-world settings. Many payers require a defined observation period, and documented data significantly strengthens your recommendation.
