How to use the percentile vs scaled score comparator
One score report can produce two different composites depending on whether a college reads percentile ranks or scaled scores. List each section with its percentile, its scaled score and the weight it carries, and this page builds the composite twice — once on each basis — reports the gap between them, and shows how many points each section contributes under either basis.
For every section the composite maximum is multiplied by the weight, divided by that basis’s index maximum and multiplied by the index value, and the parts are summed. The percentile maximum and the scaled-score maximum are entered separately, so two scales of different sizes are still compared on one common composite. Weights must total exactly 100% or the calculation stops and reports the current total, and identical composites show a gap of 0.00 pts.
One limit matters. This page draws no conclusion about which basis is better for you. The scaled-score side depends on the test population and on any conversion a college applies, and small changes to the maximums or the weights can flip the direction of the gap. No college formula is built in, so every figure comes from the published requirements.
Frequently Asked Questions
No. It reports both composites and the gap between them. The scaled-score side shifts with the test population and with any conversion a college applies, so no verdict is given.
Use the value the college treats as the top of the scale. If sections top out at different values, run those sections separately or enter the college’s published converted figures in the scaled column.
The gap reads 0.00 pts with a note that both bases give the same composite. A negative zero is never printed.
