How do we handle test retesting and practice effects in counseling practice?

• A. Always retest using the same form to maintain consistency
• B. Use alternate forms; consider retest interval; account for practice effects; document changes; avoid overuse
• C. Retesting should be avoided entirely
• D. Retest only after decades have passed

Answer: (B)

When you repeat a test, the main challenge is separating genuine change from practice effects that come with familiarity. The best approach is to use alternate forms to reduce item-specific recall, plan a sensible retest interval so you’re capturing real change rather than short-term memory or learning effects, account for practice effects in how you interpret scores (for example, considering the test’s reliability and measurement error or using a reliable change index), document what was done and why changes were observed in the client’s record, and avoid retesting too frequently to prevent artificial score shifts. This approach supports meaningful monitoring of progress while maintaining the integrity of the measurement.

Using the same form every time can inflate scores over time due to familiarity with items. Retesting should not be avoided entirely, since repeated assessment is often necessary for progress monitoring. Waiting decades to retest is impractical and insensitive to the client’s current needs.
