What are the four components of an AAC system represented by SATS?

• A. Symbols, Aids, Techniques, Strategies
• B. Signals, Aids, Techniques, Semantics
• C. Symbols, Accessories, Tools, Supports
• D. Signals, Aids, Techniques, Strategies

Answer: (A)

In AAC, the SATS framework organizes a communication system into four parts: Symbols, Aids, Techniques, and Strategies. Symbols are the representations used to convey messages (pictures, letters, words, or spoken output). Aids are the tools or devices that present those symbols, ranging from simple boards to high-tech communicators. Techniques describe how the user interacts with the system to select and send messages, such as direct selection or scanning. Strategies cover the planning and support from partners and the environment to ensure effective communication, including teaching, message organization, and conversational routines. This aligns with the option that lists Symbols, Aids, Techniques, and Strategies. Other options mix in terms like Signals, Semantics, Accessories, or Tools, which are not the standard SATS components.
