Registration guide


Registration for FIRST® LEGO® League 2017-18 "Hydro Dynamics" is now open!

FIRST® LEGO® League entry cost

Registration costs £150 + VAT per team. The entry fee covers:

  • Your Challenge Set (this is the practice field for your robot), comprises of an exclusive selection of LEGO® bricks and a roll-out field to practice on;
  • Administrative support from the IET;
  • Entry into one of the Regional Tournaments.

IMPORTANT NOTE: The challenge kits (mat and missions) will not arrive at the IET until August, so please be patient and as we get them we will deliver them to your school.

If you would like to enter two teams but only require one Challenge Set for them to share, you can apply a 50 per cent discount on your second team's registration fee to reflect the cost saved on the Set. This offer is limited to one discounted registration per school/organisation.


What happens next?

Your Challenge Set will be sent to you as soon as your registration payment has been received, but not sooner than August 2017 when the kits get delivered to the IET. If you are paying by purchase order, please process this as quickly as possible to avoid a delay in receiving your kit.


Your team will need to use a LEGO® MINDSTORMS® set to build the robot, which is not supplied. The IET are developing an official partnership with a Mindstorms equipment supplier. The details to follow shortly. All versions of LEGO® MINDSTORMS® are acceptable to use in FIRST® LEGO® League.

Note on team size

You can recruit up to ten team members aged nine to sixteen per team. Children can only participate in one team, but a coach is allowed to coach multiple teams. With growing interest in FIRST® LEGO® League  , some coaches have more than ten children wanting to join the team. If they are not in a position to form a second team, they must make the difficult decision to select the ten members to take part throughout the season. We recognise that this is not an easy choice, and appreciate the care and thought given to making this decision. To ensure a level playing field and to respect the work of the coaches who are in this position, we must enforce our ten team member policy at all FIRST® LEGO® League   events.If a team attending an event consists of more than ten children - or if it becomes clear that more than ten children have worked on the team's robot and project - the team will be informed by the event organiser that the team is more than welcome to participate in the event to gain the valuable experience, but they will not be eligible for awards.
