Ask a child who has just been handed a marked paper what they learned. Most will tell you their score. Almost none will tell you what they now understand that they did not understand a week ago.
That is not a failure of the child. It is exactly what the instrument was designed to produce.
What a number actually does
A grade is a compression algorithm. It takes weeks of thinking, struggling, revising, collaborating and occasionally breaking through, and it compresses all of it into a single symbol. Compression always loses information. The question is whether what was lost mattered.
In our experience, three things get lost every time.
The direction of travel
A 62 tells you nothing about whether a child arrived there from 40 or fell there from 85. Those are opposite stories about the same number, and only one of them warrants concern.
The nature of the difficulty
Two children can score identically for completely different reasons: one misunderstood a foundational concept, the other understood it perfectly and ran out of time. A number treats them as the same child. A teacher's observation notes do not.
Everything that was not measured
The child who spent three days helping a struggling teammate, who changed their mind publicly when shown better evidence, who asked the question that reframed the whole investigation: none of that appears anywhere on a mark sheet.
When the number becomes the goal, the learning becomes the obstacle standing between a child and the number.
The behaviour grades encourage
This is the part that concerns us most. Grades do not merely fail to capture learning. They actively shape behaviour, and often in the wrong direction.
A child optimising for marks learns, quite rationally, to avoid difficulty. They choose the essay topic they already understand. They avoid the experiment that might fail. They stop asking questions that reveal confusion, because revealed confusion feels like exposure.
This is the opposite of what we want. Every meaningful intellectual achievement in history began with someone admitting they did not understand something and choosing to sit in that discomfort.
What we do instead
There are no marks in Primary at Infinia. There are four instruments in their place, and together they tell you considerably more.
Portfolios
A curated body of your child's actual work across the year: early drafts alongside finished pieces, photographs of projects, and the child's own written reflections on what changed. Growth you can hold in your hands and see with your own eyes, rather than infer from a column of numbers.
Documented observation
Teachers record what they see as it happens: anecdotal notes, learning logs, the questions a child asked during a unit, photographs and short videos of thinking in progress. The IB calls these monitoring and documenting, and places more weight on them than on measuring.
Three-way conferences
Child, parent and teacher, in a room together, with the child leading. They present their own work, name their own goals, and explain their own reasoning. It is a conversation with your child about their learning rather than a report delivered about them in their absence.
Student-led conferences and exhibitions
Children from Nursery to Grade 5 guide their parents through a set of activities that show what life inside their classroom is actually like. And in Grade 5, the Exhibition puts a child in front of a public audience to defend an inquiry they designed themselves. Standing up and answering an unscripted question is the most honest examination we know of.
Twice a year, in writing
Formal written reports go out twice a year, at the end of each semester, through Toddle. They include teacher comments with the next step in learning, subject outcomes whether integrated with a unit or taught standalone, approaches to learning, the child's own reflection, and the goals the child set for themselves.
From Grade 6, MYP criterion-based assessment introduces detailed subject-specific achievement levels benchmarked internationally. Children meet formal assessment when they are ready for it, and by then they have five years of self-knowledge behind them.
The aim is not to hide performance from parents. It is to give you a far more accurate picture than a number ever managed.
Parents sometimes worry that without marks a child will not know where they stand. In practice the opposite happens. Ask an Infinia Grade 4 student what they are working on improving and you will get a specific, articulate answer. Ask a graded child the same question and you will usually get a number.
