Your first completion of the Clifton StrengthsFinder will yield the purest and most revealing results. For this reason, each Clifton StrengthsFinder access code is valid for only one time through the assessment.
Taking the Clifton StrengthsFinder more than once may actually decrease the accuracy of your results. The Clifton StrengthsFinder measures the presence of talents by presenting you with a pair of statements, then challenging you to make a top-of-mind choice between the two. The 20-second time limit and your unfamiliarity with the statements ensure your assessment's accuracy by making it difficult to over-think your responses.
If you are distracted or interrupted while taking the Clifton StrengthsFinder, the assessment will automatically stop after three missed responses. When you resume, it will pick up where you left off. The average person does miss responding to a few items, but because the instrument presents 177 items, missing a few will not significantly affect your results.
