11.8 Advancement Through the District Model
Teams advance through the season depending on the events at which they compete: Regional or District. This section details how District teams advance from District qualifying events, to their District Championship.
11.8.1 District Events
District teams are ranked throughout the season based on the points they earn at their first 2 home District events they attend, as well as at their District Championship. Points are awarded to teams as follows:
Category | Points |
---|---|
Qualification Round Performance | (For a typically sized District event, this will result in a minimum of 4 points being awarded for Qualification round performance. For events of all sizes, a maximum of 22 points will be awarded.) |
ALLIANCE CAPTAINS | Equal to 17 minus the ALLIANCE CAPTAIN ALLIANCE |
Draft Order Acceptance | Equal to 17 minus the Draft Order Acceptance Number (e.g. 12 points for the team that is fifth to accept an invitation) |
Playoff Advancement | Points awarded based on team participation in individual playoff rounds, and whether or not the ALLIANCE |
Judged Team Awards | 10 points for FIRST Impact Award (formerly the Chairman’s Award) 8 points each for Engineering Inspiration and Rookie All Star Awards 5 points each for all other judged team awards |
Team Age | 10 points for 2023 rookie teams 5 points for 2021 and 2022 rookie teams |
Points earned at District Championships are multiplied by 3 and then added to points earned at District events, to determine the final season point total for the team.
If there is a tie in the season point total between teams, those items are broken using the following sorting criteria:
Order Sort | Criteria |
---|---|
1st | Total Playoff Performance Points |
2nd | Best Playoff Round Finish at a single event |
3rd | Total ALLIANCE |
4th | Highest Qualification Round Seed or Draft Order Acceptance (i.e. Highest ALLIANCE |
5th | Total Qualification Round Performance Points |
6th | Highest Individual MATCH MATCH |
7th | Second highest Individual MATCH MATCH |
8th | Third highest Individual MATCH MATCH |
9th | Random Selection |
11.8.1.1 Qualification Round Performance
The calculation of Qualification performance points is done using the equation (an inverse error function) in Table 11‑5. The equation utilizes the following variables:
- – the qualification rank of the team at the event at the conclusion of QualificationR(as reported byMATCHES)FMS
- N – the number of FIRST Robotics Competition teams participating in the Qualification rounds at the event
- Alpha (α) – a static value (1.07) used to standardize the distribution of points at events
This formula generates an approximately normal distribution of Qualification Round Performance points at an event, based on rank, with most teams getting a moderate number of points, and fewer teams getting the highest or lowest numbers of points available.
Table 11‑7 displays sample Qualification Round Performance points for variously ranked teams at a 40-team event. The system will automatically generate the appropriate points for each team based on their rank and the number of teams at the event.
Rank | 1 | 2 | 3 | 4 | … | 19 | 20 | 21 | … | 37 | 38 | 39 | 40 |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Points | 22 | 21 | 20 | 19 | … | 13 | 13 | 12 | … | 6 | 6 | 5 | 4 |

In most cases, unless a BACKUP is recruited, a team plays in 100% of the Playoff
11.8.1.4 Awards
This attribute measures team performance with respect to team awards judged at the event.
The points earned for team awards in this system are not intended to capture the full value of the award to the team winning the award, or to represent the full value of the award to FIRST. In many ways, the team’s experience in being selected for awards, especially the FIRST Impact Award, the Engineering Inspiration Award, and the Rookie All Star Award (which is optional for District Championship events), is beyond measure, and could not be fully captured in its entirety by any points-based system. Points are being assigned to awards in this system only to help teams recognize that FIRST continues to be “More than RobotsSM,” with the emphasis on our cultural awards, and to assist in elevating award-winning teams above non-award-winning teams in the ranking system.
Teams only get points for team awards judged at the event. If an award is not judged (e.g. Rookie Highest Seed), is not for a team (e.g. the Dean’s List Award) or is not judged at the event (e.g. Safety Animation Award, sponsored by UL), no points are earned.
11.8.1.5 Team Age
This attribute recognizes the difficulty in being a rookie or relatively new team.
Points are awarded to 2021, 2022, and 2023 rookie teams in recognition of the unique challenges teams face in those early years, and to increase the chance that they will make it to the District Championship to compete with their
11.8.1.6 Regional Participation
District teams neither earn points for their actions at any Regionals, nor are eligible for any FIRST Championship qualifying benefits at that Regional (awards, Wild Cards, etc.). If a District team is on the winning
11.8.2 District Championship Eligibility
A team competing in a District qualifies for their District Championship by meeting 1 of the following criteria:
- A. District FIRST Impact Award Winner,
- B. District Ranking (based on total points earned at their first 2 home District events as detailed in Section 11.8.1 District Events),
Teams do not earn points at third or subsequent District events, nor at any inter-district or Regional events at which they compete during the season.
If a team declines an invitation to the District Championship, the next highest uninvited team on the list is invited, and so on, until the event capacity is filled.
- C. District Engineering Inspiration winner (qualifies to compete for the award only), and
- D. District Rookie All Star winner (qualifies to compete for the award only).
The capacity of each District Championship is shown in Table 11‑9. Each District determines the number of teams that qualify for their District Championship. These limits are based on factors including but not limited to the total number of teams in the District, available venue capacity, etc.
District Championship | Capacity | Divisions |
---|---|---|
FIRST Chesapeake District Championship | 60 | 1 |
FIRST Israel District Championship | 40 | 1 |
FIRST Mid-Atlantic District Championship | 60 | 1 |
FIRST North Carolina State Championship | 40 | 1 |
FIRST Ontario Provincial Championship | 80 | 2 |

11.8.3 District Championships with Multiple Divisions
If a District Championship has too many teams to allow all teams 12 Qualification
The process employs a “brute force iterative randomizer” and is executed as follows:
- The district team list is sorted in order of cumulative district points earned as described in Section 11.8.1 District Events.
- The list is divided into quartiles based on rank (e.g. the first quartile has the top 25% ranked teams).
- Division assignments are randomly generated using equal contribution from each quartile.
- 3 criteria are calculated for each division:
a. average strength: the arithmetic mean of the district point values of teams in a division
b. distribution of strength: the Signal to Noise Ratio (SNR) of the district point values of teams in a division. SNR is calculated as follows:
σ = standard deviation of the district points in a division
c. distribution of strength for “top” teams: The SNR of the district point values of teams in the first quartile of a division
- The 3 criteria for each division are compared to the other division(s). If the difference between the division’s value and any other division’s value exceeds the limits in Table 11‑10, the criteria is not met.
2 divisions | 4 divisions | |
---|---|---|
Average strength | 1 | 2 |
Distribution of strength | 1 | 2.5 |
Distribution of strength for “top” teams | 1.5 | 2 |
- If all 3 criteria met, event organizers publish the assignments. If any of the 3 criteria are not met, assignments are rejected, and the process returns to Step 3.

11.9 FIRST Championship: Additions and Exceptions
At the 2023 FIRST Championship, teams are split into 8 divisions. The process used to assign teams to their division is as follows:
- Rookies are assigned randomly, team by team, sequentially to divisions (i.e. a team in Division 1, a team in Division 2, a team in Division 3, a team in Division 4, a team in Division 5, a team in Division 6, a team in Division 7, a team in Division 8, then back to Division 1 again, until Rookies are all assigned to a division).
- Step 1 is with veteran teams.repeated
Each division plays a standard tournament as described in Section 11.6 Qualification
