What is SAE?
SAE is a high school agricultural education program approach to experiential learning. The FFA motto ("Learning to do, Doing to learn, Earning to live, Living to serve") was created to show what the FFA values.
You can choose anything you would like. You have to make sure too keep records as this would be a part of getting degrees. The SAEs could be things such as livestock (beef, swine, sheep, goat, etc.) or something like hydroponics.
