Each student’s learning journey is shaped not just by what they know, but by how they compare to expected patterns of progress over time. In a real classroom, teachers are constantly making judgments:

Yet these decisions are difficult to make when raw scores alone offer limited context.

To address this, education research often uses a statistical measure known as the z-score. At its core, a z-score describes how a student’s performance compares to the average performance of a group. It shows whether a learner is progressing at a similar pace to most students, ahead of them, or falling behind. While precise, the term itself is technical and unintuitive, especially outside academic or assessment settings.

At Scribo, we refer to this concept as a relative standing.

Imagine a class writing task.

Looks identical, right? But Scribo looks deeper. It is possible to get the same score for different reasons. Scribo sees:

What this tells a teacher:

Same mark. Very different teaching response.

A relative standing focuses on what matters most in teaching: understanding where a student stands in relation to others, not as a label, but as a signal. It helps teachers quickly see patterns across a class, identify students who may need additional support, and recognise those who are ready for greater challenge. Rather than fixating on absolute marks, relative standing provides context, turning data into insight.

Used thoughtfully, relative standing complements concepts like the learning sweet spot (ZPD). They help teachers gauge whether a student is likely working below, within, or above an appropriate level of challenge, enabling more responsive instruction. In this way, relative scores are not about ranking students, but about guiding support, ensuring that every learner is met where they are and given the best opportunity to grow.
