IB ACIO Tier 1 Normalisation Process

When the IB ACIO Tier 1 exam is conducted in multiple shifts, a normalisation process is applied to ensure fairness among the exam takers. This is essential, keeping in mind that the exam difficulty level might vary between different shifts.

How the Normalisation Process Works:

• Multiple Shifts: Normalisation is implemented only if the Tier 1 exam is held across more than one shift on different days.

• Difficulty Variations: Since each shift can have a different level of difficulty, raw scores alone may not accurately reflect the student’s performance.

• Score Adjustment: To eliminate any advantage or disadvantage caused by shift difficulty, raw marks are adjusted using a statistical normalisation formula.

• Statistical Calculation: This formula considers the average marks and the standard deviation of scores from all students in each shift to produce normalised scores.

• Equitable Comparison: These normalised scores allow fair comparison across all shifts.

• Shortlisting for Tier II: Finally, the normalised scores are used to determine the cut-off marks for shortlisting students for the Tier II descriptive exam.
