ACES, also known as Avon’s Coalition for Everyone's Success, is active throughout the school year.  ACES mission is to seek partnerships to foster efforts to reduce substance use disorder and promote positive, healthy decisions by people in Avon. They have middle school and high school meetings, middle school on Tuesdays at 2:15 in the middle school hall, and high school on Thursdays at 2:15 in the library. They compete annually with Team Rival and mentor students with SALSA (Students Advocating for Life Without Substance Use). Although you must be in highschool for SALSA, and have to be recommended for Team Rival, ACES is open to everybody. This club is advised by Mrs. Isidor.

Asian Student Association is a place designated for Asian voices who want to represent their culture and for others to learn about them. Events will be discussed, organized, and initiated with club members, discussing ways we can promote our identity. Correspondingly, these events' primary goal is linked to a fundraising campaign that's currently awaiting approval by the school. These collected donations will first be used to help Northern Vietnam, which recently experienced a damaging typhoon. The process begins with our connections in Vietnam, buying supplies, and renting a truck to deliver those items to our destination. Our expectations are to help those recover from the property loss, agricultural destruction, and provide food/water. As soon as we meet our goal, we'll move on to other parts of Asia that are also in need of help. This is only the beginning, so every contribution is appreciated. Together, we can create a brighter and more compassionate world for all. We want to ensure that everyone is included in the process of making this club, so ASA is most definitely inclusive to all. The club takes place every Thursday from 2:30 pm - 3:30 pm in room 227. The Asian Student Association is advised by Mr. Kinsman, and the founder of the association is Kieu-Vy Tran.

The Middle School Cooking Club is held in the cafeteria kitchen and typically meets for an hour and a half to make various delicious treats and dishes. We rotate groups of 10 each Monday and enjoy cooking and baking. Student groups choose what they would like to make, produce a shopping list, learn to read directions, measure, find appropriate cooking utensils  and navigate their way around the kitchen. Most importantly, students eat the delicious food and take pride in what they have created.

The Gay-Straight Alliance (GSA) is a safe and welcoming space for LGBTQIA+ students and allies at AMHS. We meet on Mondays from 2:30–3:00 PM in Room 133 with Ms. Lambert. Our club focuses on building community, offering support, and celebrating diversity. We participate in national LGBTQIA+ action days, host fun events like art and movie days, and hold a Pride Celebration in June. This is a supportive space where students build community and celebrate diversity. This club is available to middle and high school and is advised by Ms. Lambert.

One of the main goals of the Interact Club is to give students the chance to collaborate in a global community centered on service and intercultural understanding. Students must have strong morals and the ability to take on leadership roles in order to join. The club works on projects every year that are intended to benefit the community or school and advance global understanding. The club meets on Wednesdays from 2:30-3:30p. Students in high school have the chance to take part in enjoyable and significant community service projects through the club. Students that participate in Interact Club gain confidence in their leadership abilities and learn how to take the initiative while forming new friendships. This club is advised by Mr. Lochrie.

Science, technology, engineering, and math (STEM) club is an extracurricular activity that gives high school students the chance to learn about these subjects outside of the classroom. Students who participate in STEM clubs can enhance their critical thinking, creativity, and problem-solving abilities—all of which are valuable in the real world. They can aid students in getting ready for highly sought-after tech careers. In the past, the STEM club has projected rockets after school. This club is advised by Mrs. Shanks-Correia.
