What school reports don’t show: how to track your child’s true topic mastery

When parents receive a school report, it usually contains two main measures: a target grade alongside a working grade (such as ‘working at grade 5’), plus an effort score.

These reports give a broad snapshot, but they can hide what’s really going on. A single grade for a whole subject, such as ‘grade 6 in science’, combines performance across dozens of topics, from cell biology and organic chemistry to physics calculations.

A student can get a grade 6 overall while having a serious gap in a core area, such as balancing chemical equations or electric circuits. Equally, a student working at grade 4 might have mastered most of the course and struggle with only a few maths techniques.

To support children through KS3 and GCSEs, parents need to look beyond the report grade and see how secure each topic really is.

• A single subject grade averages dozens of topics and can hide serious gaps.
• A test score shows what your child remembered on one day, not what they still know months later.
• Specific questions about recent topics tell you more than “How’s maths going?”
• Knowledge that’s still there months later is the real sign of mastery.
• On Tassomai, the Tree and the weekly progress report show strengths and gaps topic by topic.

School reports rely on periodic tests, such as end-of-unit tests or mock exams. These are necessary, but they have three built-in limits:

• They average away the detail. A student who scores 60% on a paper gets a satisfactory mark, but nobody can see which 40% of the specification they missed.
• They’re a snapshot of one day. A test score shows what a student remembered on one Tuesday morning, not whether that knowledge will still be there three months later.
• They measure the past, not what’s remembered now. Memory fades over time [1]. A student who scored 90% on an algebra test in October may have forgotten key methods by April, but their report still reflects the autumn result.

A report grade tells you where your child stood on a test last month. Following progress topic by topic tells you what they understand today, and where they need help next.

You don’t need to re-mark test papers or tutor GCSE content to spot gaps. Three simple approaches give you a clearer picture.

Instead of “How’s maths going?”, ask about recent topics: “How are you feeling about quadratic equations?” or “Could you explain probability trees to me?” Specific questions encourage teenagers to think about what they really understand, rather than saying “It’s fine”.

Notice whether your child goes back over older topics or only studies what was covered in class this week. Real mastery shows when they can answer questions on a topic from six months ago without re-reading the whole chapter first.

Encourage your child to use study tools that show their knowledge visually. When progress is easy to see, deciding what to revise next becomes simple for both of you.

Tassomai gives families a topic-by-topic view of what their child knows in every Tassomai subject.

• The Tree. Each subject has its own Tree, which grows as your child answers questions. Green leaves are topics they know well, while orange and red leaves show where they’ve been getting questions wrong. Read more about the Tree.
• Weekly progress reports. Every Monday, parents get an email showing how many days their child was active, how many questions they answered, their accuracy and their strongest and weakest topics of the week, with a link straight to the Parent Dashboard.
• Topics that keep coming back. Tassomai’s algorithm spaces and re-tests topics over time, so the picture reflects what your child remembers now, not what they crammed last week.
• Help with weak spots. Mai Explains, our AI tutor, shows why an answer was wrong, and students can open these explanations by clicking the red and orange leaves on their Tree.

If your child uses Tassomai through school, you can find out more on our page for school parents.
