No technical knowledge is necessary! We will host a preseason coaches training meeting to help ensure you are familiar with the kits.
FIRST provides extensive lesson plans for teaching the kids everything they need to know. You're a guide to help them through the season. 
You'll work closely with the other coach to plan for how each team meeting will go. Typically, kids are broken into 2 groups and move through the 3 content areas: FIRST core values, engineering principles and model building, and research.  
The time commitment is one meeting per week for 1.5 - 2 hours for the season and participation in the End of Season Expo. Most coaches log more than 30 hours of volunteer time.
