Are you ready to discover your college program?

A healthy diet forms the foundation of healthy living. Making the right food choices can improve weight, manage chronic illnesses, and protect against disease. Individuals earning a nutrition health science certificate online can learn the basics of nutrition science, vitamins and minerals, macronutrients, and how to develop effective meal plans to meet a variety of needs. Almost 40% of American adults qualify as obese, increasing their risk of developing diabetes or heart disease. Preventative healthcare, including counseling clients to make good food choices and being physically active, remains a focus of healthcare providers.

The Bureau of Labor Statistics projects 15% growth in employment for dietitians and nutritionists through 2026. While these careers often require a minimum of a bachelor’s degree, a certificate in health science online program prepares students for entry-level employment. Many programs offer transfer credits that can shorten the time you need to complete an undergraduate degree.

Your certificate may also complement other education and careers, such as personal trainers or wellness coaches. Much of the knowledge gained through a nutrition certificate program may apply to related healthcare careers, as well, including nursing, health education, and nutrition counseling. This guide offers a look at the courses you will take, the careers you can launch, and the professional resources you can utilize.

Health and Nutrition Degree Program Ranking Methodology

Download this Badge

We selected the health and nutrition programs based on the quality of the program, the types of available online classes, the faculty, rankings, awards, and prestige, including the school’s reputation for effectively providing quality online programs.

The motto of TheBestSchools.org is Finding the best school for you. Here is how we do it:

The value of any ranking list of schools and/or degree programs depends on having a methodologically sound assessment of each school’s/program’s characteristics, especially insofar as these can be objectively measured. A college or university is a complex entity, with numerous factors to consider, and distilling these down to the place where meaningful comparisons can be made to form a defensible ranking list becomes part science and part art.

To meet this challenge—and thereby provide you with the most useful and insightful educational rankings on the Internet — TheBestSchools.org formulates our rankings based on five informational categories (six, when considering online schools). The major metrics and qualities for which we rank are these (with expanded, detailed considerations and weights listed):

1. Academic excellence based on a school’s curriculum generally or within the selected discipline [weight = 25%]

  • Weighs school against known leading schools in that discipline
  • Weighs number of core curricula listed as advanced courses within that discipline and compares against introductory courses
  • Weighs school’s curriculum against known knowledge needs of major employers in that discipline
  • Considers number and types of specializations offered within that discipline
  • Considers faculty expertise in that discipline
  • Considers range of electives within that discipline
  • Considers quality of online environment offered to students (if applicable), particularly within that discipline

2. Strength of faculty scholarship [weight = 25%]

  • Considers education background of the faculty
  • Considers years of faculty experience both inside and outside of academia.
  • Considers faculty membership and leadership within relevant, prominent associations
  • Considers academic papers published by faculty in relevant, prominent periodicals
  • Considers awards and recognitions given to faculty members from prominent organizations and from other sources

3. Reputation [weight = 20%]

  • Considers a school’s reputation among academic peers and employers regarding the following:
    • Faculty
    • Curriculum
    • “Freshness” of academic knowledge
    • Adaptability to changes in employment sectors
    • Suitability of graduates for the workplace

4. Financial aid [weight = 10%]

  • Mandatory: Requires full accreditation from an agency endorsed by the U.S. Department of Education and listed on the federal register to accept student federal financial aid
  • Considers range of school-sponsored financial aid such as scholarships and grants

5. Range of degree programs [weight = 20%]

  • Considers range of degree levels: associate’s, bachelor’s, master’s, and doctoral and professional
  • Considers range of degree subjects offered, such as art & design, computers & technology, education & teaching, criminal justice, and business

6. Strength of online instruction methodology (if applicable) [weight = 25%; subtract 5% from each of the above for online schools/programs]

  • Considers the following of the online classes:
    • Types of online technology used to deliver content
    • Pedagogy style: asynchronous, synchronous, or both (depending on the degree)
    • Extent and quality of the online, community learning environment, including options for communication, interactivity, and collaboration between students and also between students and instructors
    • Variety, breadth, and depth of coursework, and its support, including project options and online tutoring
  • Considers the following of instructors:
    • Extent of training for teaching within an online learning environment
    • Amount of timely, consistent feedback to students
    • Extent of collaboration with prospective employers to ensure suitability of instructional materials for achieving desired skills
    • Ratio to number of students in a class
  • Number and quality of internships in a student’s geographical area for applicable degrees

Because students tend to review a variety of information when choosing a school, the weight a student gives any one criterion will vary. For instance, it’s not enough to offer a carefully constructed ranking of great schools if many are too expensive or too difficult to get into.

To better serve the needs of prospective students, we are therefore increasingly offering filters that help you better use our rankings to find the schools that match your specific needs. These supplement our ranking criteria and include:

  • Accreditation
  • Public or private status
  • Acceptance rate
  • Retention rate
  • Graduation rate
  • ACT/SAT requirements
  • Cost in-state / out of state
  • Undergrad, grad, or both offered
  • Region
  • State
  • City

Get the best rankings here AND get them to suit your personal needs. That’s TheBestSchools.org advantage!

Citations: For a broader account of our ranking methodology, especially as it relates to TheBestSchools.org's underlying educational philosophy and, in other ranking articles, looks beyond academic excellence (as here) to such factors as return on investment or incidental benefit, see our article "Ranking Methodology: How We Rank Schools at TBS." Reputation of schools and degree programs can at least in part be gauged through the school or department's publishing activity, citations, and desirability. At TheBestSchools.org, we keep track of such social and peer validation: "Making Sense of College Rankings." For nuts-and-bolts information about colleges and universities, we look to the National Center for Education Statistics and especially its College Navigator. Insofar as salary and inflation data are relevant to a ranking, we look to the Bureau of Labor Statistics. Finally, nothing beats contacting schools and degree programs directly, which our researchers often do, with the result that all the entries in this article should be considered as belonging to this citation!

The Advantages of a Health and Nutrition Education

Your health science certificate opens many career options and may complement other certifications, such as athletic training or health coaching. The certificate may also serve as your first step toward a degree in nutrition or health science. Career changers often enjoy the shorter certificate programs, which allow them to begin working in their new field quickly. Individuals with a complementary degree, such as nursing, may find that a certificate prepares them for new professional credentials. Many accredited schools award college credit that transfers toward degree requirements.

However, many entry-level nutrition careers require at least an associate degree. These two-year programs require 60 credits with a combination of general education, science, and nutrition courses. Graduates can gain a broader understanding of how nutrition impacts overall health and wellbeing and research methods for nutrition science. An individual hoping to become a registered dietician must complete a minimum of a bachelor’s degree.

Choosing an Online Health and Nutrition Program

Earning your certificate in health science online opens exciting new career opportunities, but students should carefully evaluate each program’s requirements, costs, and curriculum to ensure they see a return on their investment. Think about the program components most important to you and your future success.

The items below offer a starting point for evaluating schools. Talk to admissions representatives, faculty members, and current students, when possible, to help determine if the program represents a good match for your overall education and career goals. Many schools offer high-quality nutrition and health science certificate programs. By researching schools now, you can find the school that best meets your needs.

Program Cost
Program costs will vary significantly from school to school. Public, in-state institutions often offer the lowest price for college-level courses, but many schools now provide tuition discounts to online students regardless of their state of residence. Private schools or for-profit organizations offering health science certificates online often charge the most for their programs.
Transfer Policies
Your certificate may represent the first step in a long educational journey. Ensuring your school offers transfer agreements with other colleges can ease the transition from one program to the next. Transferring credits also lowers the cost of future degrees by reducing the number of credits needed for an associate or bachelor’s degree.
School Size and Type
While large public universities often serve thousands of students each year, individual programs often seek to maintain smaller classes. Small classes allow more student participation and increased interaction between faculty and students. Consider the class size offered at each school and the learning environment that best serves your needs.
Program Length
Most certificate programs require one year or less to complete. The credit requirements may be 12 to 24 credits, depending on the certificate sought. Schools offering accelerated class formats, such as eight-week semesters, often allow students to earn more credits over a year while reducing the number of classes enrolled in each term.
On-Campus Requirements
While online programs allow students to complete most certificate requirements remotely, some schools require attendance at some on-campus events. These may include an orientation before starting classes, in-person academic advising, or hands-on learning opportunities. Schools may offer exemptions from these requirements in certain situations, such as military service, family responsibilities, or burdensome travel costs.

Accreditation for Online Health and Nutrition Programs

Verifying your school’s accreditation status ensures you earn a recognized, respected certificate and that you can transfer your credits later if you want to work toward an associate or bachelor’s degree. Accreditation serves as an independent quality assurance for consumers that schools offer a robust and relevant curriculum.

Regional accreditation, the most common institutional accreditation, reviews a school’s overall academic program. Schools must hold an accreditation recognized by the U.S. Department of Education or the Council for Higher Education Accreditation to participate in many federal student financial aid programs. Though some programs at a school may qualify for financial aid, be sure to check your certificate program meets these requirements.

The Association of Nutrition and Foodservice Professionals offers a specialized accreditation for nutrition and health science certificate online program. Graduates of approved programs may sit for the Certified Dietary Manager national exam. The Accreditation Council for Education in Nutrition and Dietetics of the Academy of Nutrition and Dietetics accredits nutrition education programs from the associate degree level through doctorate programs. While a certificate program may not meet the requirements for this programmatic accreditation, attending a school whose degrees meet these standards can ensure a quality curriculum.

How Long Does It Take to Get a Certificate in Health and Nutrition?

Certificate programs vary in their number of courses and length. Some programs require at least one year to complete, while others take only a few months. Students should evaluate the depth and breadth of certificate programs, along with accreditation status and available financial aid assistance to ensure the program meets their professional needs. Some schools offer self-paced certificate courses, where students progress through the curriculum on their own. Enrollees may pay one fee for access to course materials for six months or a year. If they complete all the courses within that time, they will not pay additional tuition.

Other schools follow a traditional semester or accelerated semester schedule, with beginning and end dates and assignment deadlines set throughout the term. In this format, students balancing work and school may need more time to complete all the courses. Many schools offer a set tuition rate for full-time students, so taking more than 12 credits per semester can accelerate your certificate completion and save in overall tuition costs.
