The IPS "International Point Score" rating system was developed by Swimnews to allow comparisons among different events. The IPS system assigns point values to swimming performances, more points for world class performances typically 1000 or more and fewer points for slower performances. The IPS system scores events with values from 0 to 1100 points. Point values are assigned at the start of each season based on all-time performances. The IPS charts are revised yearly and have one set of points for Short Course and another for Long Course. The IPS points rating system allows for comparisons among various events, swimmers of different sex, age, etc. It can even be used for scoring competitions.
