About FIRST® LEGO® League (FLL®)


FIRST® LEGO® League is a global science and technology challenge for teams of students, to encourage an interest in real world issues and develop key skills that are crucial for their future careers. The students work together to explore a given topic and to design, build and program an autonomous LEGO robot to solve a series of missions.

FLL is for young people aged 9 to16 years, working in teams of up to ten students with a supporting adult coach. Each year FLL releases a new challenge for the teams. The challenge involves a robot game and a research project, and students will need to demonstrate the FLL core values throughout all their work.

Teams usually have twelve to sixteen weeks to work on the challenge before they compete in their chosen Regional Tournament. 

At the tournament, teams will score points on each of the three parts of FLL:


Robot Game

Teams build a robot using a LEGO® MINDSTORMS® kit that they program to autonomously complete a series of missions on a specialised field and to score as many points as possible.


Through the project, teams learn more about the science and engineering behind the challenge theme. The teams identify a problem related to the theme, research the issues and propose a solution.

Core Values

While competing, the teams have to demonstrate core FLL values including Gracious Professionalism® and Coopertition®, encouraging high quality work, unqualified kindness and respect and learning.

The winners of the Regional Tournaments go forward to the UK and Ireland Final. The top teams from the UK and Ireland Final will then be invited to compete at the FLL World Festival in the USA or at other international FLL events.


FLL is CREST Accredited

Students can complete either a Bronze or Silver CREST Award during this project. For further details please visit The British Science Association.
