The Plum Discovery Survey is a universal assessment of cognitive ability and personality. Your results are not job specific until combined with the employer’s match criteria and therefore the assessment does not need to be retaken for every job application.
Research has found that personality stabilizes during early adulthood*, meaning that results on the test will change very little if taken after your early 20's.
Plum’s test has good test-retest reliability. We found similar Plum Trait and Talent scores for individuals who took the test two times across an interval of 2-4 weeks.
The Plum Discovery Survey is designed to capture your natural, ingrained tendencies. Those tendencies tend to be stable over time. Therefore, a Plum Profile is unlikely to change over time. This is because we are assessing core characteristics about a person - their cognitive abilities and personality - which research has shown are relatively stable once in adulthood**.
For example, those who are extraverted are very unlikely to become introverted. Those who prefer to have more stability in general are unlikely to enjoy uncertainty on a regular basis. That being said, as you continue to grow and develop what will likely change is your compensatory skills. A compensatory strategy is a technique individuals use to help them perform a Talent well, even when it is not something that comes natural to them or drives them. So while you gain more experience, you will not be changing who you are at your core, but you will be developing these strategies to still be able to perform those Talents well when you need to in the workforce.
That said, if you deliberately select completely different answers and don't answer honestly, your results will change and may change drastically. Our research demonstrates that authentic, honest responses will provide you with the most valuable information to support you in your career path.
