What medical research for high school students actually looks like
Medical research for high school students can involve analyzing existing health data, reviewing published studies, studying gene activity, or investigating health-related questions through approved surveys. You can contribute to medical research without diagnosing patients, testing treatments on people, or working in a clinical setting.
Clinical research studies health and medical care in people, often by evaluating treatments, diagnostic methods, or patient outcomes. Clinical trials, which test interventions under carefully controlled conditions, require qualified medical teams, ethics oversight, and appropriate approvals. Epidemiology, the study of how diseases and health conditions affect different populations, offers a more accessible starting point for many high school researchers.
Your options depend on the question you’re asking, the resources available, and the supervision you can access.
| Type of medical research | What you’d do | Realistic for high school? |
| Clinical trials | Study the effects of treatments on patients | No, not independently |
| Wet lab biomedical research | Investigate cells, proteins, or other biological processes | Sometimes, through a structured program with appropriate supervision |
| Public health data analysis | Examine disease patterns across populations | Yes |
| Systematic or literature review | Compare findings from published medical studies | Yes |
| Gene expression data analysis | Compare patterns of gene activity across samples | Yes, with some coding or suitable analysis tools |
| Survey study | Investigate health-related behaviors or experiences | Yes, with required ethics approval |

Your first project doesn’t need to produce a new treatment or medical discovery. A careful analysis of an existing dataset can help you answer a focused question, explain a health trend, or identify an area that deserves further study.
1. Be honest about what you can and can’t do
Your research plan must fit the safety rules of your school, science fair, and research institution. Under Society for Science’s ISEF human participant rules, student researchers cannot independently diagnose illnesses, administer medication, or perform medical procedures on other people. You also can’t draw blood from another person as part of your project.
Hospitals and university laboratories set their own rules for younger researchers. Some restrict laboratory access for students under 16, while others limit the tasks students aged 16 or 17 can perform, particularly when work involves infectious materials or other hazards. Check the requirements before applying to a program.
These restrictions don’t prevent you from doing useful research. A strong medical project can investigate an important question using existing data, without involving patients or handling biological samples. For example, you could study changes in cancer survival rates or examine whether published studies report similar findings about a health condition.
2. Pick a medical question you can answer with data you can get
Start with a specific health question, then check whether you can access the information needed to answer it. A broad topic such as diabetes is a starting point, not a complete research question.
Narrow your topic by identifying a population, a time period, and a measurable outcome. Instead of asking why diabetes occurs, you might investigate changes in diabetes prevalence among American adolescents across available survey periods. Prevalence means the proportion of a population that has a particular condition at a given time.
Before committing, check whether a suitable dataset or enough published studies exist. Some databases don’t include every age group, location, or health measure, and those gaps can make an otherwise interesting question difficult to investigate.
What are good medical research topics for high school students? You could examine public health trends, compare findings on sleep and adolescent health, investigate cancer survival patterns, or review research on how environmental exposures relate to health outcomes. Explore 15 Disease Research Project Ideas for inspiration, then use How to Choose a Research Topic as a High School Student to assess whether your idea is manageable.
3. Use free public health datasets
Government health agencies publish datasets that let you investigate medical questions without recruiting patients or collecting samples yourself. Researchers use these resources too, although working with a public dataset still requires you to understand how its information was collected and what conclusions it can support.
Start with these four resources. Each suits a different kind of medical question.
| Dataset | Who runs it | What’s in it | Good for | How to get access |
| NHANES | CDC’s National Center for Health Statistics | Interviews, physical examinations, and laboratory results from a national sample | Studying nutrition, blood pressure, diabetes, and other health measures | Download public-use files, including SAS transport files in .XPT format. Follow the data documentation and use the appropriate survey weights. |
| CDC WONDER | Centers for Disease Control and Prevention | Public health statistics, including deaths by cause and birth data | Examining changes in mortality rates or birth patterns across locations and years | Use the online query tool. Follow its privacy restrictions and never attempt to identify individuals. |
| SEER | National Cancer Institute | Cancer incidence and survival data | Comparing cancer trends by type, age, and stage | Register for access to SEER Research Data and agree to its data-use terms. Analyze the data using SEER*Stat, a Windows application. Research Plus access has additional requirements, including institutional affiliation and a supervisor or mentor. |
| Gene Expression Omnibus (GEO) | National Center for Biotechnology Information, part of the National Library of Medicine | Gene expression datasets from published studies | Comparing gene activity across disease and comparison groups | Search and download available datasets for free. GEO2R lets you compare groups through a web interface, although you still need to assess data quality and interpret the results carefully. |

Each dataset has its own rules. CDC WONDER’s restrictions prohibit attempts to identify individuals and prohibit publishing certain birth or death statistics based on counts of nine or fewer. NHANES provides survey weights to account for its sampling design, so using the wrong weights can lead to misleading estimates. GEO2R is convenient, but its results depend on the quality and suitability of the dataset you select.
Public, de-identified data often lets you avoid recruiting participants, but you should still check your school’s or science fair’s rules before starting. For more on research ethics, see Tip 5.
4. Try a systematic or literature review
A literature review lets you investigate a medical question by comparing published instead of collecting new data. A systematic review takes this further by using a planned, repeatable method to search for studies, decide which ones qualify, and summarize their findings.
For example, you could review studies examining the relationship between sleep duration and adolescent health. You would set clear criteria for which studies to include, record how you searched for them, and compare their methods, populations, and results. This helps you spot patterns as well as disagreements between studies.
The PRISMA 2020 guidelines include a checklist and flow diagram to help researchers report how they identified, screened, and selected studies. They’re useful tools for planning and documenting a systematic review, though following PRISMA alone doesn’t guarantee a high-quality review.
A meta-analysis goes a step further by combining numerical results from multiple studies using statistical methods. That can require more advanced skills, so a carefully scoped review is a sensible first project.
Use How to Write a Literature Review in High School to plan your paper, and Semantic Scholar for High School Researchers to find relevant studies.
5. Get IRB approval before you survey or study people
If your project involves human participants, get the required ethics approval before recruiting anyone or collecting data. An Institutional Review Board (IRB) is a group that reviews research plans to check that participants are treated safely and ethically. Under Society for Science’s ISEF rules, human participant studies require prior IRB approval, and the board must have at least three members, including a medical or mental health professional.
This applies to surveys, interviews, measurements, and other research involving people. A survey about sleep habits or stress can still require review, even if you don’t collect physical samples. For participants under 18, parental permission and the student’s own agreement, called assent, may also be required.
Don’t collect names alongside health information unless your approved plan requires it and explains how you’ll protect that information. Store research files securely and limit access to people who need them.
Publicly available, de-identified datasets may be exempt from human participant review under science fair rules, but don’t assume every dataset qualifies. Read Do High School Researchers Need IRB Approval? before designing a survey or interview study.
6. Learn the basic epidemiology you’ll need
Medical research requires you to understand what a health statistic measures before you draw conclusions from it. Epidemiology, the study of how diseases and health conditions affect populations, uses several concepts that will help you interpret public health data correctly.
Start with these four:
- Counts and rates: A count tells you how many events occurred. A rate relates those events to a population, often over a period of time. Comparing counts between a large state and a small state can be misleading if you ignore their population sizes.
- Age-adjusted rates: These rates account for differences in age distribution between populations. They’re useful when comparing diseases that become more common as people get older.
- Correlation and causation: Two health measures can change together without one causing the other. An association is a reason to investigate further, not proof of cause and effect.
- Confounding: A confounder is a factor that affects both things you’re comparing and may distort their apparent relationship. For example, age could influence both a health outcome and the likelihood of having a particular risk factor.
You may also encounter relative risk, which compares the probability of an outcome between two groups, and odds ratios, which compare the odds of an outcome between groups. The two measures aren’t always interchangeable.
Choose tools that match your dataset and the analysis you need. A spreadsheet may be enough for basic CDC WONDER results, while R or Python can help you analyze NHANES or gene expression data. For more terminology, see Horizon’s Research Terms Glossary and What Is a Hypothesis?.
7. Find a mentor who does medical research
A research mentor can help you choose suitable methods, understand medical literature, and recognize problems before they affect your project. You don’t necessarily need a physician. Depending on your question, a researcher in epidemiology, neuroscience, genetics, public health, or medical sociology may be a better fit.
Look for mentors through medical school outreach initiatives, university departments, hospital research programs, public health departments, and structured online mentorship programs. When contacting a researcher, explain your specific interest, mention a paper or project of theirs that caught your attention, and ask whether they mentor high school students. A focused request is easier to respond to than a general request for an internship.
Some institutions run structured programs for younger researchers. For example, St. Jude’s High School Program describes an eight-week summer research immersion program for Memphis-area high school students interested in biomedical science. Eligibility and program details can change, so check the official page before applying.
You can also explore these Horizon guides to NIH’s High School Summer Internship Program, Stanford SIMR, and the Scripps Student Research Internship. For more options, check out the guides to oncology summer programs, free online medical programs, medical camps, and genetics research programs.
Horizon Academic Research Program offers online, one-to-one mentorship with a PhD scholar or professor over several months, culminating in a research paper of roughly 20 pages. Its current subject areas include Neuroscience and Medical Sociology, which may suit students interested in brain science or the relationship between society and health. If you want to study medicine-related questions without depending on local laboratory access, a mentored online project is one option to consider.
Remember that clinical exposure and research are different. Shadowing a physician can help you understand patient care, but it doesn’t replace conducting a research project. Explore shadowing programs for high school students if you’d like to learn about clinical practice alongside your research.
8. Share your work through competitions and journals
Once you’ve completed your analysis, present your findings in a way that lets other people understand your question, evidence, and limitations. You can consider research competitions, student journals, or both, depending on your project’s scope and eligibility.
Options include Regeneron International Science and Engineering Fair (ISEF), which has Biomedical and Health Sciences and Translational Medical Science categories, Regeneron Science Talent Search, and the Junior Science and Humanities Symposium. Each has its own eligibility and submission requirements, so read the official rules before deciding where to submit.
You can also explore research journals for high school students and how to publish research in high school. For a broader overview, see 15 Research Competitions and ISEF: How to Qualify and What Judges Look For.
Build your presentation around one clear chart, the main finding, and an honest account of what your data cannot tell you. Don’t claim that an association proves a cause, that a small sample represents everyone, or that your analysis establishes a treatment’s effectiveness. Clear reasoning matters more than dramatic conclusions.
Frequently asked questions
