Diagnosing Placement Aptitude-Test Errors: the core idea
Aptitude losses come from concept gaps, slow methods, reading errors, selection and time pressure. Topic scores alone cannot distinguish which intervention will work.
A practical method for diagnosing placement aptitude errors
Rework missed and slow items, tag the cause, and calculate loss patterns across several timed sets. Practise the leading cause in isolation, then retest it in a mixed company-style assessment.
Checks and pitfalls for diagnosing placement aptitude errors
Do not memorise answer patterns from leaked material or assume every employer uses the same test. Follow the authorised current assessment information.
