Hey, It's Alan!
I'll be explaining the National Beta Club (Beta) as both a service club and a competition. Firstly, Beta is community service club with the core principle of, "Leading by serving others." Most Beta clubs have a main service project that establishes their role in the community.
Each school or chapter have their own requirements, but generally you must maintain an above average GPA, good character, and volunteer a certain number of hours.
"Well, why should I care?" Excellent question. Essentially, Beta is another way to show off your talents and interests. From the arts (music, visual arts) to academic (math, science, etc.), you'll be able to compete and advance through competitions at convention.
Furthermore, colleges love community service and through Beta you will be able to talk about the projects you have been a part of. I personally talked about my community involvement for most of my college essays, from working at the local food pantry to partnering with a t-ball team.
Finally, Beta seniors are given the opportunity to apply for the Beta scholarship that opens in November. Over 200 seniors are selected for scholarships ranging from $1,000 - $20,000. A link to more information can be found here.
National Beta Club places great importance on its four pillars: Achievement, Leadership, Character, and Service.
Achievement- Typically students must maintain a GPA of 3.5 to remain members. You were only required to pass AP and Dual credit classes at my high school rather than stay above a certain grade. As such, this rule isn't really hard and fast.
Leadership- As a Beta member you must be willing to take charge during service projects or even the classroom. From my experience you will be required to lead projects more often than you would think.
Character- Students must maintain a reputable character throughout their time in the club. Any form of detention or suspension may result in you being kicked from the club and being unable to rejoin at your sponsors discretion.
Service- In my opinion the most important pillar. Students must remain active members in their club and community. At my high school every member of Beta was required to work a minimum of 30 hours of service.
There are three main competitions times for Beta: leadership, state, and national convention. At these conventions there are academic, art, and on-site competitions.
The academic tests are taken online, well before the convention date. These test subjects range everywhere from Agriscience to French however each school is only allowed to have one student/to a test/to a grade. Meaning a school can have 4 students taking the Spanish test but they must all be for a different grade level (Freshman-Senior). A list of the Academic competitions can be found here.
The on-site competitions contain the most variety being anything from a soloist playing their instrument to a team of students building a Rube-Goldberg machine. These competitions take place at the convention center and are judged by a team.
