Check the qualification and the teaching fit
If you want a school-trained teacher, ask which teaching qualification and status the tutor holds and where these apply. Then ask about their experience teaching A-level Chemistry: a credential alone does not tell you how they will explain a calculation or respond when an explanation has not clicked.
- Qualified teacher status (QTS)
- QTS is a professional teaching status in England. If it is important to your choice, ask the tutor to confirm that they hold it; do not treat every qualification title as another name for QTS.
- Postgraduate certificate in education (PGCE)
- A PGCE is an academic qualification in education. Teacher-training courses can lead to QTS, a PGCE, or both, so check the actual award and status rather than assuming they always come together.
- Chemistry knowledge and course experience
- Discuss the tutor’s subject background, the A-level specifications they teach and how they would work through your marked answer. Look for an explanation you can follow, including why a tempting wrong answer fails.
