This season, the boys and girls state basketball tournaments will be determined, in part, and seeded by the CHSAA Seeding Index.

This Index combines data from the RPI, CHSAANow coaches poll, MaxPreps rankings and Packard ratings.

These data points have been combined, with each counting for 25% of the formula, and the result of that data is below.

Each ranking system is translated into a percentage in order to combine them. To do this:

  • Teams have their total points in the coaches poll divided by the total possible points. For example, if a poll has 20 voters, there are 300 possible points as a first-place vote is worth 15 points.
  • The RPI, Packard and MaxPreps rankings determine their percentage by comparing every team to the maximum value in that classification. For example, if the maximum RPI value in a class is .700, every other team in that classification is compared to that value.
  • To account for some negative values in the MaxPreps and Packard ratings, the minimum value is added to every value in the classification to ensure the lowest possible rating is 0, and not negative. This only occurs if the minimum value in a classification is negative.
  • These percentages are then added together and divided by four, so that each accounts for 25% of the final formula.

The snapshot of the CHSAA Seeding Index has been posted for both boys and girls basketball, and provides data through games completed on March 2 (so long as those scores were entered into MaxPreps).
