Laboratory Learning Program Essays Guide 2026

Princeton’s Laboratory Learning Program is a competitive and intensive summer research program that accepts only New Jersey high school students who are age 16 and over. Its inclusion on an applicant's resume can, by itself, move the needle significantly for admissions officers. As a result, it is an opportunity that all high school students who have prior research experience or top placements in academic competitions such as the Science Olympiad or AMC should pursue. This article will tell you how to approach the numerous essays that they ask you to write as part of your application.

1. What do you hope to get out of a research experience at Princeton? (250 words)

You should begin this essay by vividly portraying yourself, in the first person, working through a STEM-related problem. This could involve conducting technically demanding research, competing in an academic competition, or pursuing an independent or recreational scientific project, such as an at-home experiment or an AI project. As you describe yourself engaging with this problem, clearly demonstrate the technical skills you were using. Focus on one or two technical challenges that you found particularly difficult to apply in pursuit of a solution.

From there, explain how this experience revealed that you still have room to grow as a budding scientist, mathematician, or engineer, specifically in terms of the technical mastery required to succeed in your idealized career path. For instance, a STEM experience might expose the need to strengthen your ability to navigate peer-reviewed literature; understand how statistical methods extract insight from data and assess the reliability or significance of those insights; communicate scientific findings effectively to both technical and nontechnical audiences; identify problems that genuinely spark your curiosity because of their depth and complexity; develop greater mathematical maturity; or more effectively account for known phenomena when building models, while also recognizing which non-obvious factors should be considered.

I may have overlooked other valid goals and aspirations, but these examples illustrate a broader principle: the strongest motivations are deeply rooted in the research process itself. The goal is not to cram all of these motivations into a short 250-word essay. Rather, you should select the reasons that matter most given your lived experiences and show the reader a brief but vivid snapshot of those moments to establish a compelling and personal motivation.

2. Describe What You Have Learned From Previous Science Classes, Laboratory Or Research Experience. (250 words)

For this essay, research your chosen areas of study for this program and clearly demonstrate how your programming experience, understanding of statistics, Excel skills, fascination with the unknown, and grit will benefit your research team. Show the reader how you use NumPy or scikit-learn to perform calculations relevant to planetary geology, such as cross-validating a planetary image classifier, or how spending all night trying to denoise an image won't demotivate you.

Paint a picture of yourself applying your hard skills, complemented by your soft skills, to help your research team accomplish their goals. If your strengths primarily lie in soft skills, focus on how these have fostered perseverance and autodidactic abilities, enabling you to learn quickly and independently. Discuss how these qualities have made you unafraid to ask questions when uncertain and have given you an open mind.

Even if emphasizing soft skills, try to reference specific technical scenarios that might arise during your participation in the research group. Demonstrating that you've researched what your chosen area typically entails will impress the reader. To conclude the essay, discuss how you look forward to further developing these skills by testing them, understanding their limitations, and transcending them in a real-world, intensive research environment.

3. What Do You Hope To Contribute To A Research Team? (250 words)

For this essay, you want to demonstrate your understanding of the types of problems that your mentors for this program will be working on during the summer. ChatGPT can help significantly with this research phase. Once you have a comprehensive understanding, you should illustrate how you would contribute in your mentor's lab by applying the skills you mentioned in your previous essay to solve problems you are likely to encounter while working with them.

Part of this assessment is determining what types of problems are most likely to arise while working with your specific mentor. Write this essay as a hypothetical scenario where you are working in their lab and applying the skills you discussed in your previous essay to solve relevant challenges. Use a first-person perspective so the reader can visualize you as a productive contributor to their research group.

Remember that focusing on soft skills or taking a frivolous approach will not be effective. The program administrators are seeking candidates who can meaningfully contribute to their research efforts. This is not a research program designed for beginners.

4. What Are Your Career Interests And Plans For College? (250 words)

For this essay, I suggest starting with an anecdote that highlights a personal motivation driving your long-term academic and career aspirations. As with the first essay, it is crucial to articulate a very clear vision of your goals. Specifically, you should mention the highest degree you intend to pursue, the subject area of focus, the type of career you aim to achieve with that degree, and how pursuing this career will contribute to making a significant positive impact on the world.

The purpose of this essay is to provide a compelling personal reason for your ambitions, clearly state your goals, and demonstrate to the reader the meaningful impact that can result from your success. The aim is to inspire the reader to root for you as you work toward achieving these objectives.

Finally, I recommend concluding by discussing how the Princeton Laboratory Learning Program will play an indispensable role in helping you accomplish your goals. Be sure to reference how achieving the short-term goals described in your previous essay will serve as a foundation for reaching your long-term aspirations.

5. Summer Availability (If you are selected, actual days and times will be discussed by the approving department) (250 words)

Make sure that you state that you are available all days during the summer, outside of religious observance of course. You can state the other activities you are doing during the summer, but if so, make it clear that if a conflict between them and the Princeton Laboratory Learning Program came up, you'd always forgo that activity to dedicate the necessary time to your research group.
