Explain a Child's School Report Grading System to a Confused Parent

The report is full of letters and numbers on a scale that changed since you were at school, and parents' evening is in two days. This translates the grading system into plain English, tells you if the marks are actually a concern, and gives you specific questions worth asking instead of a vague how's she doing.

**Explain** the grading system in plain English:

2. Whether the grades shown are age-expected, above, or below, and how to tell
3. What questions are worth asking the teacher based on what the report shows
4. What, if anything, genuinely needs following up versus normal variation
