RePLAY Challenge Season Resources

FIRST LEGO League Challenge 2020/2021 – RePLAY Season Resources


Opportunities to play are all around us. In the RePLAY Challenge, the creativity of young minds will transform spaces – from open fields to empty parking lots – into opportunities to play. What activities can we create there? How can the games and the places where we play change to reflect the people playing or the equipment we have?

This season, FIRST LEGO League Challenge participants will harness their natural curiosity and use their critical thinking and imagination to explore what future spaces for play will look like. Guided by adult mentors and working as a team, students will apply their STEM skills to participate in an Innovation Project to solve a real-world problem, build and program a LEGO® robot, and compete in an exciting, mission-based Robot Game.

Are you ready to play? Join the FIRST LEGO League community for RePLAY, part of the 2020-2021 FIRST robotics season, FIRST GAME CHANGERS, powered by Star Wars: Force for Change.

The FIRST® LEGO® League tournament experience includes 3 judged components:
Core Values, Project, and Robot Design. The judging process is designed to evaluate each team’s accomplishments throughout the season and to provide feedback.

Judges use a rubric for each area to record their feedback. The rubrics guide the judges through key criteria that reflect what is most important about the FIRST® LEGO® League experience. Rubrics also create a consistent way to differentiate between teams at different levels of achievement. Your team will be assessed as Beginning, Developing, Accomplished, or Exemplary in each category.

The rubrics are not scoresheets. They provide insights into the information your team shared with the judges and where they excelled or might need improvement. Awards are guided by rubrics but are not issued by a “rubric score.” After the event, completed rubrics should be returned to teams to help them understand their strengths and areas for improvement. In addition, teams are encouraged to use the rubrics as a roadmap throughout the season. Pay close attention to the higher levels of achievement to understand the criteria that will help define a reliable, well-programmed robot design, a thoroughly researched and effective Project, and a high-functioning team that embraces the FIRST® Core Values.


REPLAY Season Judging Documents


Core Values (3 minutes)

We expect teams to display the Core Values throughout the season. Tournament organizers, judges, referees, and others are expected to uphold the Core Values, too. Teams should receive the benefit of the doubt whenever possible.

Teams will be given the opportunity to explain themselves if an issue arises. Judges or referees may ask your team questions about who worked on your robot or Project idea. Sometimes teams assume that another team could not have done the work they present without the direct involvement of adults. Remember that children are remarkably creative, and some are highly sophisticated at programming or software applications for presentations. Don’t assume that you know what another team is capable of, and don’t let your team members make assumptions either.

Prepare for a Tournament
Unlike other areas of FIRST® LEGO® League, teams usually do not have tangible results (like a robot or a Project idea) to show to the Core Values judges at a tournament. Be prepared to talk about how you apply Core Values to all you do throughout the season. All teams operate differently, and teams can be successful with different styles. Some teams have a strong leader, and some have a democratic approach. Some teams assign each child has a specialized role, and other teams share all responsibilities equally. As long as team members understand and use the Core Values in their interactions, no working style is better than others.

Core Values judges will assess how well your team understands and integrates these values into their tournament, meetings, and daily life. Be ready with examples of how your team demonstrated the Core Values throughout the season. Have team members take turns sharing these examples in front of the group, and ask other children to give feedback. Remember to keep the feedback constructive.
There are multiple formats for Core Values judging. Some events will rely on interviews, while others will use a hands-on teamwork activity. Your event may require teams to create a Core Values Poster as a tool to communicate with the judges, so check with your tournament organizer.
Teams do not need to bring their robot or Project materials to Core Values judging sessions.


Innovation Project (5 minutes)

Each team has 5minutes to present— not including setup. Exceeding the time limit is a common mistake. Some judges will interrupt your team and stop the presentation at 5 minutes while others may shorten the question time afterward to compensate.

Judges at a tournament will only consider what your team tells them, so make sure your team shows or describes how they met the requirements. Anything they want the judges to know should be included in your team’s presentation. After your team’s presentation, the judges may ask questions of your team as a whole or may direct questions to individual team members. Your team should be prepared for either format.

To be eligible for Project awards, your team must:

  1. Meet any season-specific requirements outlined in the Challenge.
  2. Identify the problem your team chose to research.
  3. Describe your team’s solution.
  4. Describe how your team shared its findings with others.
  5. Meet the format requirements:
    • Present live; teams may use media equipment (if available) but only to enhance the live presentation. (to be conducted virtually for season 2020/2021)
    • Include all team members; each team member must participate during the judging session in some way.
    • Setup and presentation must be completed in 2 minutes or less with no adult help.


Robot Design (5 minutes)

Robot Design judges will interview and observe your team. Some events require formal Robot Design presentations, while at other events the judges may simply ask your team questions. Have your team prepare a basic introduction to the robot and the roles each member had in designing, building and programming it. Robot Design judges will ask teams about their mechanical design and the programs they wrote. They will want to see and hear about any innovative techniques or strategies the team came up with to solve problems and complete Missions. Through their questions they will ensure that the children completed and understand all work associated with building their robot.

Bring your team’s programs to the judging session. They may be on a laptop computer, tablet, or printed on paper. Judges may ask to review some parts of your team’s programs. There may be a competition table with Mission Models in the judging area. Your team should be prepared to demonstrate their solution to at least one of the Missions and talk about their strategy. Review the information about your tournament carefully and contact the tournament organizer if you have any questions.

Pay attention to any information provided by your tournament organizer. Even when formal presentations are not required, some judges simply prefer to start interviews with a general, “Tell us about your robot.” Help your team prepare for different scenarios and make sure the team members are comfortable demonstrating the robot.

Judges at events are usually volunteers, just like many coaches. They may be educators, experts in an area related to the Challenge, or perhaps a community member or industry leader who cares about inspiring children.

The judging process at tournaments is overseen by a key volunteer known as the chief judge. The chief judge leads the judging team and works with the tournament organizers to ensure that the event meets judging standards. Just as the head referee determines the recorded score at the Robot Game tournament table, the chief judge’s word is final when it comes to any judging questions or decisions at an event. If your team has questions about a judging session, please ask to speak with the chief judge right away.


Judges Are All Around

In addition to evaluating teams using the rubrics during scheduled interview sessions, judges may also use less formal conversations and observations throughout the event to learn more about teams.

Remind your team that judges may not openly demonstrate who they are, but their ears and eyes are wide open. Lending a helping hand to a team that forgot to bring something speaks loudly about your team’s understanding of Gracious Professionalism®.

Judges will also consider any input provided throughout the day by referees, event volunteers and others who interact with the team. Help your team members to understand the process and encourage them to feel comfortable speaking with judges and other event volunteers.


Judging Subjectivity

With the exception of Robot Performance, which is objectively determined by scores earned on the competition table, team achievement in all other award categories is subjectively judged. Even the most experienced and skilled judges will not assess every team in exactly the same way. Judges work in pairs or small groups to create more balance in the way they review teams. In addition, tournament organizers train their judges and use other tools to create a level playing field. Judged awards are inherently subjective and this is important for all teams to understand. Awards are determined through a normalization process, which includes deliberations and discussions.


Led by the chief judge, FIRST LEGO League deliberations rely on an in-depth discussion of all teams eligible for awards. Using observations and evaluations captured by the rubrics as one form of input, judges consider any and all additional team information gathered throughout the day.
Team achievements are reviewed and contrasted as the judges engage in often-intense discussion to decide which teams will be recognized with awards. Judges work together as a team to create an initial ranking of award candidates based on a team’s relative strengths and weaknesses compared to other teams and the award criteria as defined in the rubrics.

Once these initial rankings are complete, the judges enter the final phase of deliberations. Each Champion’s Award candidate is discussed. All judges vote to determine the winner. After this award is given, other awards are determined using the rankings from initial deliberations. Judges follow the distribution policy outlined in the next section.

Awards Distribution

The goal of the FIRST LEGO League awards distribution process is to congratulate as many teams as possible who most deserve recognition at the tournament. With the exception of Robot Performance (which any team may receive based on the points they earn), teams may only win 1 Core Award per tournament.

Judges must consider how to recognize the best set of award candidates. Sometimes this means an award may not go to the individual team with the highest ranking in a category if that team is already being recognized with another award. For example, if a team receives the Teamwork Award they will not also receive the Presentation Award even if they were initially ranked highest for presentation. They will receive the award in the area where judges agree they excelled the most.

FIRST LEGO League judges deliberate to determine how to recognize the entire field of teams in the most appropriate way possible, and to celebrate the achievements of all teams.


Awards Structure

The Overall Champion’s Award is the most prestigious award that a team can win at an official FIRST® LEGO® League event. It celebrates the ultimate success of the FIRST® mission. Core Values, Project, and Robot Design are considered equally important for this award. In addition, teams must earn Robot Game scores in the top 40% of teams at the tournament to be considered for the Champion’s Award.

The remaining awards fall into the following categories:

  • Core Values Awards
    • This team displays extraordinary enthusiasm and spirit, knows they can accomplish more together than they could as individuals, and shows each other and other teams respect at all times.
  • Innovation Project Awards
    • This team utilizes diverse resources for their Innovation Project to help them gain a comprehensive understanding of their problem, have a creative, well-researched solution and effectively communicate their findings to judges and the community.
  • Robot Design Award
    • This team uses outstanding programming principles and solid engineering practices to develop a robot that is mechanically sound, durable, efficient and highly capable of performing challenge missions.
  • Robot Performance Award
    • This award celebrates a team that scores the most points during the Robot Game. Teams have a chance to compete in at least three 2.5-minute matches and their highest score counts.
  • Coach/Mentor Award
    • Coaches and mentors inspire their teams to do their best, both as individuals and together, and without them, there would be no FIRST LEGO League. This award goes to the coach or mentor whose leadership and guidance is clearly evident and best exemplifies the FIRST Core Values.
  • Optional Awards
    • Recognize the most remarkable teams for which a standard award does not exist. These may take the form of Judges Awards or a separate local award with criteria established by an individual tournament organizer.


Awards Eligibility 

Doing well on the rubrics and achieving a high score in the Robot Game are important for winning awards, but they are not the only factors. Your team also needs to follow the FIRST LEGO League Participation Rules and policies to be eligible for awards.

Make sure your team and everyone associated with your team understands policies that may impact award eligibility. If you need clarification, the time to ask questions is before an event. Once on site, all decisions impacting award eligibility are determined by the local judge advisor and/or event organizer. Just like decisions made by the head referee at the table, their authority is final.
