Skills ladder
Stage 1
New joiner
- Prepares samples and cleans equipment
- Runs basic tests as per method
- Records results neatly
Stage 2
Independent
- Performs routine tests independently and checks results
- Calibrates instruments as scheduled
- Raises out-of-limit results quickly
Stage 3
Senior or lead
- Investigates deviations and complaints
- Trains analysts and reviews results
- Validates new methods with the head
Training path
First weeks
- 1
Lab safety and housekeeping
The quality head shows chemical handling, waste, PPE and labelling. The joiner demonstrates safe preparation and signs.
- 2
Test methods
A senior analyst teaches each routine test from the written method. The joiner repeats tests on known samples and the senior compares results.
- 3
Records
Teach the lab notebook, result sheet and signing rules. The head reviews entries daily and corrects them in front of the joiner.
First year
- 1
Calibration and instrument care
Teach balance, pH meter and other instrument checks. The analyst keeps the calibration log and the head audits it.
- 2
Out-of-limit response
Teach how to retest, report and hold material when results fail. The head reviews the response in each case.
- 3
Microbial and stability basics
Where relevant, teach sampling, plates and incubation or stability test routines. The analyst follows the method and the senior checks readings.
Towards senior
- 1
Deviation investigation
The analyst learns to trace a failed batch to cause with production. The head reviews investigations.
- 2
Training junior analysts
The senior analyst trains and checks newcomers' results. The head compares results to reference samples.
- 3
Method improvement
The analyst proposes method changes with data. The head approves and updates the written method.
Performance review
A monthly 1-to-1 with the quality head using records and audits, plus a half-yearly written review with a blind sample exercise.
What to measure
| Measure | How it is seen |
|---|---|
| Result accuracy | Reference sample or repeat tests |
| Record quality | Notebook and sheet audits |
| Instrument calibration | Calibration log review |
| Speed of reporting failures | Time from result to notification |
| Safety practice | Observation and waste handling |
| Investigation quality | Written deviation reports |
Evidence to bring
- Lab notebook
- Calibration log
- Out-of-limit register
- Blind sample results
- Training sign-off
Questions to ask in the review
- Which tests are you least sure about?
- What out-of-limit results did you report?
- Were you pressed to change a result?
- How are your instruments?
- Where did records have gaps?
- What lab safety worries you?
- What would you like to learn?
Pitfalls
- Letting production push lab staff on release decisions
- Not training on why limits exist
- No blind sample checks
- Letting calibration lapse during busy periods
