GCSE Maths Misconception Diagnostic Assessment | Automated Tracker & Intervention System

GCSE Maths diagnostic assessment with worked solutions, automated misconception tracker, intervention groups and 24 targeted reteach cards.
GCSE MATHS MISCONCEPTION DIAGNOSTIC SYSTEM

Go beyond a total score and identify the mathematical misconception behind the error.

This complete GCSE Maths diagnostic resource combines a 24-question assessment, fully worked teacher solutions, an automated Excel analysis tracker, printable error coding and 24 intervention cards. It is designed for Year 10, Year 11, intervention groups, resit classes, tutoring and departmental assessment.

The assessment covers all six broad GCSE Mathematics domains:

Number
Algebra
Ratio, Proportion and Rates of Change
Geometry and Measures
Probability
Statistics

WHAT MAKES THIS RESOURCE DIFFERENT

Most assessment trackers show which topic was weak. This system goes one step further by linking each diagnostic question to a specific probable misconception.

Examples include:

treating ratio as a fraction of the total
additive rather than multiplicative scaling
losing signs during substitution
reversing rise/run when finding gradient
failing to update probability after a draw without replacement
averaging score labels instead of using frequency × value
using the discounted value as the base in reverse percentages

The teacher can therefore move from:

MARK → MISCONCEPTION → INTERVENTION → REATTEMPT
