NAQT computes “D-Values” to issue invitations to its Intercollegiate Championship Tournament (ICT) and Community College Championship Tournament (CCCT) to teams that did not qualify automatically. The inputs to the D-Values are teams’ performances at the Sectional Championship Tournaments (SCTs) and Community College Sectional Championship Tournaments (CC SCTs).

D-Values are calculated to compare the performance of teams that competed at different qualifying tournaments.

The system is based on, and named for, a proposal by former NAQT writer Dwight Wynne, who played quiz bowl at Capistrano Valley High School, UCLA, and UC-Irvine.

This page describes the original calculation of D-Values, which was in use from 2010 to 2017. It was also used for the 2018 CC SCTs, but has been superseded.


The system makes use of these statistics:


The team’s raw D-Value is computed to simulate the points it would score in a 20-tossup game against average opponents. It equals

20 × (Adjusted TUPPTUH + Adjusted BHPTUH × Adjusted PPB)

This computation is done separately for the Division I and Division II fields.

After the raw values are computed, they are listed in order for each SCT and a correction is applied to ensure that invitations do not break the order of finish at an SCT. Starting at the top of each SCT, each team is checked to see if it finished above one or more teams with higher D-Values. If it did, then that team and every team between it and the lowest team with a higher D-Value are given the mean D-Value of that group and ranked in order by their finish (and, if still tied, by raw D-Value).

After those order-of-finish corrections are applied for each SCT, the rankings are combined into a single list for each division.

Public Nature

The raw data for the teams and the computed values will be posted on NAQT’s website.
