Learn how to find, evaluate, and develop a strong Diamond Challenge idea. This guide covers 10 brainstorming areas for high school students and practical questions to help you identify problems, research opportunities, test ideas, and choose a concept worth pursuing.
The Diamond Challenge is a global entrepreneurship competition for students ages 14–18. Teams of 2–4 students develop an original venture concept and present their ideas through one of two competition tracks: Business Innovation or Social Innovation.
The Business Innovation track focuses on solving a customer problem through a sustainable business model that can generate revenue, while the Social Innovation track focuses on addressing a social or environmental challenge and creating measurable positive impact.
What Makes a Strong Diamond Challenge Idea?
A strong Diamond Challenge idea begins with a clear understanding of a problem and the people affected by it. When students start with a real need, they have a stronger foundation for developing a solution that is relevant, practical, and worth pursuing.
For example, students may notice that their classmates have difficulty finding affordable academic support outside school hours. This observation could lead to many possible solutions, including a tutoring service, platform, or community-based program. The important first step is understanding the underlying problem before deciding how to solve it.
From a business perspective, problem discovery is one of the most important stages of developing an entrepreneurial idea. Students should investigate who experiences the problem, when it occurs, how frequently it occurs, and what makes it difficult to solve. Speaking with potential customers or beneficiaries can provide valuable insights and help students identify needs that may not be obvious at first.
Students should also research how the problem is currently being addressed. Existing products and services can reveal how much demand exists and where there may be opportunities for improvement. A strong concept often emerges when students identify a specific gap between what people currently have and what they actually need.
The next step is to consider the value of a potential solution. For a Business Innovation concept, students should understand who the customer is, what value the solution provides, and why the customer would be willing to pay for it. For a Social Innovation concept, students should identify the people or communities who would benefit and consider how the proposed solution could create meaningful social or environmental impact.
Students can conduct interviews, research the market, develop a simple prototype, or run a small experiment to gather feedback and start testing your ideas. Early testing allows teams to evaluate their assumptions and refine their ideas before developing a more complete solution.
The Diamond Challenge provides students with an opportunity to work through this entrepreneurial process, from identifying a problem and recognizing an opportunity to conducting customer discovery, developing a value proposition, testing a solution, and presenting their concept. Approaching the competition as a process of research, development, and experimentation can help students build a more thoughtful and evidence-based project.
A promising idea may change as students learn more about their potential customers or beneficiaries. The strongest concepts are often the result of careful research, direct feedback, and several rounds of refinement rather than a single idea developed at the beginning of the process.
Prepare Your Idea for the Diamond Challenge
20 Diamond Challenge Ideas for High School Students
The best Diamond Challenge ideas often begin with problems students can observe directly. Recent finalists have developed ventures around student-athlete scheduling, adaptive education, sustainable materials, healthcare access, agricultural technology, senior support, and digital productivity.
These examples show how broad topics can become focused opportunities. A student interested in sustainability might explore food waste, agricultural waste, or school-event waste. A student interested in education might focus on one specific learning challenge rather than education as a whole.
1. Academic Support for Students
Many students need extra academic support outside of their regular classes, whether they are preparing for an academic competition, struggling with a particular subject, or looking for a deeper challenge. However, access to the right support can depend on factors such as location, schedule, cost, and the availability of qualified instructors.
A potential venture could focus on a specific group of students with a clear academic need, such as students preparing for a specialized competition or students who need additional support in a particular subject. Starting with a well-defined group can make it easier to understand students’ challenges, talk to potential customers, and develop a solution that addresses a real need.
2. Food Waste in Schools
Food waste is a common issue in schools, but the reasons behind it can be different from one cafeteria to another. Schools may prepare more food than students actually eat, serve portions that are too large, or have limited options for redistributing meals that are not used.
A student team could focus on one part of this process and explore how it could be improved. For example, they might track how much food is wasted, when it happens, and what types of food are most often thrown away. Understanding the problem at a school level can help the team identify a specific opportunity and develop a practical solution.
3. Financial Education for Teenagers
Teenagers start making financial decisions at a relatively young age, from managing their spending to opening a bank account or making their first purchase online. However, many students have limited opportunities to learn how to handle these decisions in a practical, everyday setting.
A venture could focus on one specific area, such as budgeting, saving, responsible spending, or understanding common financial products. Students could explore what teenagers actually struggle with and develop interactive tools, workshops, or other resources that make financial concepts easier to understand and apply in daily life.
4. Technology Support for Older Adults
Technology is now part of many everyday tasks, but older adults may still find things like using smartphones, managing online accounts, making digital payments, or navigating new apps difficult or frustrating.
A venture could focus on one specific technology challenge and provide simple, personalized support. Talking directly with older adults could help a student team understand which problems come up most often and what kind of support would actually be useful to them.
5. Reusable Systems for School Events
School events often require decorations, food containers, signs, and other supplies that may only be used once or a few times. Schools may also end up purchasing similar materials for different events throughout the year.
A venture could explore a system for schools to share, rent, or reuse event supplies instead of purchasing new items each time. A student team could research what schools currently spend on these materials and identify which items could be reused more easily, potentially helping schools reduce both costs and waste.
6. Access to Educational Resources
Students do not always have the same access to technology, books, enrichment programs, or other academic opportunities. What is available can vary significantly depending on a student’s school, community, and resources.
A venture could focus on one specific gap and explore a practical way to improve access. Working directly with students, families, or schools in the community can help a team better understand the problem and determine whether the solution is actually making a difference.

7. Technology for Agriculture
Farmers are increasingly using technology such as sensors, data tools, and automation to improve how they manage their farms. However, smaller farms may find some of these technologies too expensive, complicated, or difficult to adapt to their needs.
A venture could focus on one specific challenge farmers face and explore a technology-based solution that is simpler and more accessible. Speaking with farmers and understanding their day-to-day needs would help a student team determine whether the problem is significant and what kind of solution could be useful.
8. Environmental Waste Solutions
Many materials that are thrown away still have potential to be reused, repurposed, or turned into something useful. The challenge is often finding a practical way to collect, process, and reuse these materials.
Students could explore a specific type of waste, such as food, agricultural, textile, or plastic waste, and look for opportunities to give it a second use. The venture could focus on creating a useful product from discarded materials or developing a simpler, more efficient way to process and reuse them.
9. Sustainable Fashion for Teenagers
Teenagers often buy new clothes, replace items they no longer wear, and get rid of clothing that is still in good condition. This creates opportunities to make clothing last longer through resale, repair, reuse, or exchange.
A venture could focus on one part of this process, such as clothing resale, repair, customization, or school-based clothing exchanges. Talking with students about why they stop wearing or discard certain clothes could help a team identify a specific problem and develop a solution that fits how teenagers actually shop and use clothing.
10. Sustainable School Supplies
Students go through a wide range of school supplies each year, from notebooks and writing materials to backpacks and other everyday items. Many are replaced before they are completely used, creating opportunities to reduce waste and make these products more sustainable.
A venture could explore reusable products, alternative materials, or ways to collect and redistribute unused supplies. Talking with students about what they currently buy, replace, and throw away could help identify a practical solution that offers both an environmental benefit and a clear reason for customers to try something new.
How to Choose Your Diamond Challenge Idea
After brainstorming, you may have several ideas that seem promising. Before finalizing an idea, we recommend you think about which idea you can actually research, test, and develop, using these questions:
1. Is there a real problem?
A strong idea starts with a problem that real people experience. Try to identify a specific group of customers or beneficiaries and understand what they are struggling with. Avoid choosing an idea simply because the technology or product sounds innovative. Start with the problem and look for evidence that it matters.
2. Can you talk to the people affected?
Talking to potential customers or beneficiaries is one of the best ways to understand whether a problem is worth solving. The Diamond Challenge encourages students to conduct customer discovery interviews and test their assumptions.
Think about whether you can realistically reach the people who experience the problem. If you cannot talk to them or observe the problem directly, it may be difficult to understand what they actually need.
3. Are existing solutions good enough?
Finding an existing solution does not necessarily mean you need to abandon your idea. In fact, existing solutions can help you understand what customers already use and where there may still be room for improvement.
4. Can you test the idea?
You do not need to build a complete company before submitting your concept. Start with a small experiment that can help you learn something about the problem or your proposed solution. Example experiments can include interviewing 20 potential customers, creating a simple prototype, or running a small pilot.
5. Does the idea fit Business Innovation or Social Innovation?
The Diamond Challenge has two tracks, and the distinction can help you shape your concept from the beginning. Your track should match the main purpose of your venture. This will also affect the type of customers or beneficiaries you study, the evidence you collect, and how you measure success.
