Written by Collegewise Staff | Mon, Dec 8, 2025

Many students are considering alternative ways to enhance their college admissions candidacy and differentiate themselves from other highly qualified candidates. Capstone projects are a great way to show tangible evidence that a student can apply their knowledge and think critically about their studies. 

If you’re a student or parent hearing this term for the first time, you’re likely wondering, “What is a capstone project?” You’ve come to the right place. We will unpack capstone projects, offer examples, and share more insight on why more students are considering capstone projects over traditional extracurriculars.

Key Takeaways:

  • A capstone project is a final initiative that brings a student’s studies to completion by applying their knowledge and learning to the real world. 
  • Capstone projects are important because they signal college readiness and a student’s ability to take their learning to the next level. While not every student will need to have a capstone project, most students applying to highly selective colleges or programs will want to explore capstone projects. 
  • Capstone projects can be rooted in virtually anything. The most popular capstone projects for high school students include taking on an entrepreneurial endeavor, conducting independent research or publishing written work, and creating a product.
  • The best capstone projects aren’t just about exploration; they aim to solve real-world problems and create something new. 

What is a Capstone Project?

  • At its core, the capstone project meaning describes a multi-faceted project or assignment that a student completes at the end of high school. It’s a crowning achievement that brings a student’s studies full circle and allows them to apply their skills and knowledge to solve real-world problems. It is typically a long-term endeavor, taking anywhere from a few months to a full year to complete. 

    The key goals of a capstone project include:

  • Showcasing a student’s deep understanding of a topic
  • Highlighting their commitment to an area of study or a major
  • Providing a tangible academic project that demonstrates a student’s interest and skill 

How Capstone Projects Make Students Stand Out in College Applications

A well-executed capstone project can be a game-changer for students applying to highly selective colleges or selective majors. It can position a student as a future innovator or signal college readiness and intellectual vitality to college admissions officers. Capstone projects offer evidence that a student has not only studied a specific subject, but is also capable of applying their learning to the real world. Unlike other students who simply describe being passionate about their studies, students who present capstone projects are providing undeniable evidence. 

Capstone projects can also provide rich content for letters of recommendation. The teacher or mentor writing the recommendation letter can speak directly to a student’s initiative, problem-solving skills, and commitment to their project. Ultimately, making the recommendation memorable, impactful, and unique from other students. 

Finally, capstone projects signal college readiness. Many capstone projects are conducted independently or involve complex components. Seeing a capstone project on a college application speaks to a student’s ability to take on more rigorous coursework or college-level assignments. 


Capstone Project vs. Extracurricular Activity: What’s the Difference?

A common question among parents and students is how a capstone project differs from a traditional extracurricular activity. In short, a capstone project is a deep dive into a field of study over the course of several months (or years) and produces original work. An extracurricular activity is a breadth of interest in which a student is a contributing member.

How to Start a Capstone Project: A 5-Phase Approach

To maximize a capstone project, it’s important that students take the time to reflect on their interests, opportunities, and goals. Through this reflection, they will start to narrow down potential avenues. 


Here are some next steps for students looking to start a capstone project:

  1. Reflect and align. Make a shortlist of potential capstone projects that are exciting, related to an area of interest, and are feasible. 
  2. Look to the community. Tap into a local network and identify opportunities around you.
  3. Find a real need. Be innovative. Be creative, bridge gaps, and solve real-world problems. 
  4. Consult with mentors. Work closely with a teacher, mentor, or community organizer to guide your efforts and keep you grounded. 
  5. Scale. Start small and scale. Progress matters more than perfection in the beginning. 


 

Which Students Should Have a Capstone Project?

Not every high school student needs a capstone project to get accepted to college. The United States has plenty of colleges and universities that only assess students on their academic performance. In these circumstances, students can skip the capstone project and focus on improving their grade point average (GPA). 

Where capstone projects make a big difference in the college admissions process is when a student is applying to a highly selective college or major. Harvard, Stanford, MIT, and other Ivy League institutions expect students to engage in a capstone project throughout high school. Students who apply without a capstone project are at a disadvantage. 

Likewise, while most colleges and universities will gladly accept students without capstone projects, there are specific majors that have more rigorous requirements for applicants. These are popular majors such as Computer Science, Business, Economics, and other related fields. Due to the volume of applications colleges receive yearly, the best way for students to stand out from the crowd is by submitting a capstone project as part of their extracurricular profile. 

Final Thoughts on Capstone Projects

More students are looking to take on capstone projects as the college admissions process becomes increasingly more competitive. While capstone projects are important and will ultimately provide students with an edge, students shouldn’t take on a capstone project out of obligation. These projects require a lot of time, attention, and dedication from students. The best way to see a capstone project through to completion is by putting our 5-phase approach into action and kickstarting something that brings genuine joy. Only then will a capstone project be fulfilling and strengthen a college application.
