Professional judgment is required
Safety and Accessible Alternatives
Every investigation needs activity-specific review before students begin.
01
The classroom safety gate
Chapter guidance is a planning aid, not a substitute for district policy, an SDS, facility rules, student health plans, or teacher expertise. Run and inspect any adapted investigation before class.
- Identify hazards, PPE, supervision, handling, cleanup, storage, and disposal.
- Check allergies, sensory needs, mobility, ventilation, and emergency access.
- Use only district-approved materials, quantities, equipment, and procedures.
02
Keep the construct; change the access route
Each room includes a low-risk paper, data, model, narrated, tactile, or keyboard-accessible alternative. A safer alternative should preserve the reasoning being assessed rather than simply remove the intellectual work.
Professional review remains essential
Adapt this guidance to district policy, adopted materials, actual learners, available facilities, and current authoritative sources.
