Preserve the learning goal while offering multiple ways to understand instructions, contribute to the design, and show knowledge. Provide captioned demonstrations, high-contrast diagrams, keyboard-accessible templates, physical samples, step cards, vocabulary support, adjustable group roles, and alternatives to fine-motor file work. A student can lead measurement, testing, documentation, or critique without being the machine operator.
Plan access with the learner and relevant school staff before the lab session. Do not assume that a disability automatically excludes someone, and do not improvise around guards, interlocks, ventilation, supervision, or required clearances. If a task creates a barrier that cannot be safely removed, provide an equivalent route to the same academic evidence.
