MEASURING GAINS IN PERCENTILES ALLOWS YOU TO SEE WHAT HAS BEEN ACCOMPLISHED, UNDERSTAND HOW THAT CLIENT IS PERFORMING IN RELATION TO THEIR PEERS, AND MAKE INFORMED DECISIONS ABOUT WHAT INTERVENTIONS MAY STILL BE NEEDED.
When someone comes to LearningRx for help, the first thing we do is administer a comprehensive Cognitive Skills Assessment. The test takes about an hour, is reasonably priced (typically less than $299), and shows us exactly which cognitive skills are weak and which are strong. After LearningRx brain training, we administer a second Assessment to measure change in cognitive skills.
Cognitive scores are commonly presented in three forms:
- Age Equivalent Scores can be used up to the age of about 16 and indicate how one client’s scores compare with the average scores of other age groups.
- Standard Scores indicate how far above or below average an individual score falls, using a common scale (ex: “average” of 100). IQ is normally presented as a standard score with “100” being average.
- Percentile Scores indicate where a client would rank in a hypothetical group of 100 clients. This is the measure we focus on primarily. Percentile scores show how someone ranks in performance when compared to 100 of their peers. In other words, if 100 clients lined up according to how well they performed on a test, a client who scored as well or better than 38% of their peers would line up 38 places from the end of the line. We would describe this client as being in the 38th percentile. If someone ranked in the 38th percentile before LearningRx brain training, and in the 59th percentile six months later, he or she has “moved up in line” by 21 places. In other words, that client has improved by 21 percentile points.
Why do we report our gains in percentiles rather than percentages? Percentages don’t tell the whole story. A client who starts out performing in the 5th percentile and jumps to the 15th has experienced a 200% gain. That sounds really impressive, but that client is still performing behind 85% of his or her peers. When gains are measured in percentiles, however, you can see what has been accomplished, get a clear picture of how that client is performing in relation to his or her peers, and make informed decisions about what interventions may still be needed.
We call it brain training. Our clients (and their families) call it life changing.
Find out if cognitive training can make life easier for you or someone you love. The first step is to call a LearningRx center near you and schedule an initial assessment. The assessment takes about an hour and is very reasonably priced. Even better, it will give you a world of information about cognitive strengths and weaknesses, as well as insights into the next best step. Call us today and get the answers you need.
