My sone was an officer in his high school FCCLA. He got a $1000 scholarship towards college from them.
I think FBLA is the other club that is good for HS kids. That’s future Business Leaders. Also a scholarship opportunity.
I am the advisor for the TSA Technology Student Association and I work very closely with the FFA Future Farmers of America. Both of these groups do an amazing amount of work preparing kids for future opportunities.
