Choose a STEM competition by first checking who can enter, then matching the work students want to do to the time, budget, equipment, and adult support your school can provide. A research project, a robotics season, and a menu of conference events demand very different commitments. Confirm current local rules before signing up or buying materials: eligibility, registration capacity, dates, and equipment can vary by year, edition, and location.
Start with the students, not the competition name
Before comparing programs, write down the students’ grade levels and ages, where they live and attend school, their interests and experience, and the realistic number of teammates. Eligibility may depend on more than age: citizenship or residence, full-time enrollment, school or chapter membership, state limits, team size, or the oldest teammate’s grade can all matter.
For example, Toshiba/NSTA ExploraVision accepts teams of two to four and assigns the grade band according to the oldest student. Its rules describe eligible U.S. and Canadian citizens living in specified locations and enrolled full-time in an eligible school setting; students may be no older than 21. The program says, “Students enter as a team of 2-4 students with a teacher/coach and optional mentor (no individual entries).” Its FAQ says teammates may attend different schools and live in different states, and that permanent residents may participate but are not prize-eligible. Read the complete ExploraVision rules and requirements and FAQ rather than relying on a short eligibility summary.
Match the format to the learning experience
Ask what students should spend their time doing: investigating and presenting an idea, building and programming a robot, or choosing among several event disciplines. The format shapes the skills practiced, the preparation schedule, and the resources the team needs.

Research and future-technology project: ExploraVision
ExploraVision asks students to research an existing technology and imagine how it could develop in the future. A submission includes a title, an abstract of up to 150 words, a description of up to 11 pages, a bibliography, and a technology launch flyer. Judging covers creativity, scientific accuracy, communication, and the feasibility of the future vision. The current cycle uses a 2026–2027 rubric, according to the program overview.
This format may suit students who enjoy research, writing, and explaining a design concept more than building a physical device. The stated deadline for this cycle is 8:00 p.m. ET on January 27, 2027; confirm it and all eligibility details on the official rules page before planning your calendar.

One international partner serving Germany, Austria, and Switzerland says Challenge registration typically opens in late April or early May and remains open through October if regional spaces are available. It lists team participation at €344 plus country-specific shipping and class participation at €739 plus shipping in those three countries. These are not worldwide prices or guaranteed current rates. The partner says a Challenge team needs a robotics set, recommends SPIKE Prime, and lists EV3 and NXT as alternatives. It describes evaluation across Robot Game, Research, Robot Design, Core Values, Coaching, and Overall Performance.

Many event choices: Technology Student Association
The Technology Student Association (TSA) offers a range of competitive events rather than one single project format. Its middle-school guide for the 2026 and 2027 conferences includes Biotechnology, Coding, Robotics, STEM Animation, and Video Game Design, among others. The guide sets event-specific team sizes and participation limits; for example, it lists Robotics as three teams of two to six members per state and STEM Animation as three teams with at least two members per state.

| Decision factor | What to establish |
|---|---|
| Eligibility | Age and grade rules, citizenship or residence conditions, school enrollment, team composition, and any chapter, state, or country restrictions. |
| Work students will do | Research and presentation, robot building and programming, or a choice among event disciplines. |
| Access and capacity | Local organizer, qualifying route, open registration status, event slots, and any school, chapter, or state caps. |
| Calendar | Registration deadlines, submission or conference dates, recruitment, coaching, practice, project work, and travel. |
| Total cost | Registration, required equipment, consumables, replacement parts, transport, and staff or volunteer time. |
| Preparation support | Available teacher or coach, mentor, practice space, safety oversight, and time to learn the rules and judging criteria. |
Do not treat one organizer’s fee or equipment list as a general estimate. For instance, FIRST’s U.S. 2026–27 page describes parallel editions using different technology, while the euro amounts above apply to a partner’s specified central European countries. Ask the local organizer about scholarships or loaner equipment; do not assume either is available.
Use this decision workflow
- Define the team. Record students’ grades and ages, location, interests, experience, and likely team size.
- Choose the experience. Decide whether the priority is building and coding, investigating and presenting a project, or selecting from multiple event disciplines.
- Confirm eligibility and access. Ask the organizer about age and grade rules, membership requirements, team limits, state or chapter caps, qualifying routes, local capacity, and registration status.
- Work backward from the calendar. Put deadlines on the school calendar, then allow time for recruitment, coaching, research or construction, practice, and travel.
- Calculate the full budget and support load. Include fees, kits and materials, replacements, transportation, and the adults’ time. Confirm who can coach, supervise, and help students prepare.
- Read the current rules before purchasing. Check the season’s rubric, safety requirements, and exact equipment specifications. Match any kit to the edition and local event rules.
Make the final choice against current local rules
For a research-oriented team, ExploraVision offers a defined project submission and judging framework. For students who want a sustained robotics challenge, FIRST LEGO League combines robot missions with judged team and project elements, but edition and local requirements determine which experience and equipment apply. For a school that wants students to pursue different technical interests, TSA’s event menu can offer more variety, subject to current chapter, state, and conference rules.
Before committing, have the local organizer or school advisor confirm eligibility, available places, dates, required materials, costs, and the applicable rules for the current season. That final check is what turns a promising fit on paper into a competition your team can actually enter and support.
