The key characteristics of a Jack & Jill competition include:

1. Random Pairings: Unlike traditional dance competitions where dancers often compete with a chosen partner, Jack & Jill competitions involve random pairings. Dancers are paired up with different partners through a random draw, which can occur before each round of dancing.
2. Spontaneity and Improvisation: The format emphasizes the dancers’ ability to adapt and improvise with different partners and to different music. This tests their skills in leading and following, musicality, and overall dance versatility.
3. Multiple Rounds: Competitions often have multiple rounds, starting with preliminaries and moving to semi-finals and finals. Dancers are judged individually in the early rounds, and only in the final rounds might they be judged as a couple.
4. Music Variety: The music for Jack & Jill competitions is typically chosen by the organizers or DJs and covers a range of tempos and different Bachata styles adding to the challenge for the dancers to showcase their adaptability.
5. Judging Criteria: All Judges are looking for qualities such as timing, technique, connection with the partner, musical interpretation, and overall presentation. The ability to connect well with a randomly assigned partner is particularly important.
6. Community and Fun: While competitive, Jack & Jill competitions are also known for their fun, community-oriented atmosphere. They encourage social interaction and are often a highlight at dance events and festivals.

The judges will evaluate each participant in the corresponding role using a scale from 0 to 5. The average of these scores will then be calculated to determine the results.

In the preliminary round and if needed in the semi-finals, the competitors are not ranked in a specific order, a call-back system is used instead.

Every dancer gets judges individually, neverless partnership is an important part of the judging.

Every song will be danced with a random partner. This can be determined by rotating or shuffeling after/before every song.

The judges select competitors for the next round (essentially yes or no) and determine alternates.

The event organizer determines how many competitors are promoted for the next round. There are two possibilities:

• Pre-fixed number of semi-finalists or finalists
• Considering the natural break in the ranking (often it occurs, that the first group of ranked competitors are close together before there is a break to the second group with the rest of the ranked competitors)
  
  

The callbacks will be announced to the competitors. After the awards the detailed scores of judges without headjudge will be posted.

In the finals, all the competitors get placed by the judges by defining a rank:

1st place, 2nd place, 3rd place, etc. while duplicate placements are not allowed.

For the final placement a majority is needed. If no competitor has a majority of the same placement, the

next placement is added to the previous placements until a majority is reached:

1st and 2nd place (= 1-2)
1st, 2nd and 3rd place (= 1-3)
etc.

If two or more competitors have an equal majority, the numerical value of the ordinals for each competitor is added. The competitor with the lower sum get ranked higher. If the sums for two and more competitors are equal, the next placement is added to the previous placements.
