Grade 6 Mathematics: All Strands Below At-Risk Threshold

The overall mean score for Grade 6 Mathematics is 30.4%, with 20 learners currently at-risk. All assessed curriculum strands are performing below the at-risk threshold for this sitting, with Measurement showing a chance-corrected mastery of 0.0%.

Given that all strands are below the threshold, it would be helpful to check if assessment conditions were consistent before planning interventions. A closer look at the assessment conditions, paper difficulty, or administration would help understand these results.

Primary analysis

Content area mastery

Sorted from weakest to strongest — CI lower bound tells you the most you can confidently rule out.

Strands = the CBC content areas that make up this subject. Performance is reported per strand because a subject-wide average hides where the gap actually is.

Interpretation guide

How to read this report

median 1 question/LO → per-LO is item-evidence not mastery; mastery claims at strand; 2026 harder next-grade paper; misconceptions are distractor hypotheses.

Sparsity note: outcomes with 1 question cannot support diagnostic conclusions — the 1 question — directional only tag marks these throughout.
