What to measure
| Measure | How it is seen |
|---|---|
| Safety practice | Observation, incident log and drill participation |
| Readiness of experiments | Faculty remarks and practical class records |
| Stock accuracy | Register against physical stock |
| Equipment condition | Breakage and repair records |
| Care of chemicals and waste | Labelling, storage and waste log |
| Student support | Faculty and student feedback |
Evidence to bring
- Issue and return register
- Stock check sheets
- Breakage log
- Safety drill record
- Instrument calibration record
Questions to ask in the review
- Which experiment is hardest to prepare?
- What is missing or running low?
- What breakage happened and why?
- Did you see unsafe handling by students?
- How do you label and store chemicals?
- What training would help?
- What do faculty ask for at short notice?
- What would improve the lab layout?
Pitfalls
- Treating lab assistants as helpers and giving no safety training
- Blaming the assistant for missing items without checking the register
- Surprising the assistant with practicals not on the plan
- Never visiting the store until an inspection
