What do the "Best Score," "Level," and "Confidence" columns mean in the results table? (en)

These columns display the key indicators of assessment performance and integrity:

Best Score: Shows the employee's highest score (on a scale from 0 to 100) across all test attempts.

Level: Indicates the corresponding proficiency level based on the international CEFR scale (A1 to C2).

Confidence: Displays a percentage that reflects the technical reliability of the assessment result, indicating whether the score is highly reliable or whether it may have been affected by irregular behaviors (such as leaving the test tab during the assessment).
