Which AAC layout is dynamic and may require multiple alphabetical boards?

• A. Chronological Grid
• B. Schematic/Activity Grid
• C. Alphabetical Grid
• D. Taxonomic/Category Grids

Answer: (C)

An Alphabetical Grid is dynamic and often split across multiple boards to spell words. When users are composing messages, they select letters one by one to form the desired word. Because there are many letters to access, the interface usually shows only a subset of letters on any given screen and moves to another board or page for the next set of letters. This dynamic, multi-board approach lets the user continue spelling without overcrowding a single screen with all 26 letters plus punctuation and common letter combinations. Other layouts organize symbols by time, activity, or category, which are typically accessed within one board rather than switching between multiple alphabet pages, so they’re less about spelling through sequential letter boards.
