If you’re concerned that an online program may offer a different curriculum than a traditional program, you’ll be happy to know that the coursework should be nearly identical. In addition, you’ll have access to your professors and classmates, just as you would in a brick-and-mortar school.

However, if you choose a clinical or research track, you’ll need to complete labs, clinical work, research, and/or fieldwork onsite in a healthcare facility approved by your degree program—just as you would in a campus program.

  • Program Length: They typically take the same amount of time as campus programs. However, some may allow you to finish your degree in less time by progressing through coursework at your own pace as you achieve established competencies rather than taking courses in a semester-based format.
  • Prerequisites: The same as they are for onsite programs.

Health Science Practicum or Internship

As a budding professional, you will want to put your education into practice. This applies to all students, not only those who are working toward professions in clinical practice. When you complete a practicum or internship, you will not only earn credits, but you’ll also have valuable, real-world experience when you sit down for your first interview with a potential employer. In fact, you might be able to convert a practicum into a job opportunity or lay career groundwork with a network of contacts and referral sources.

Schools often refer to practicums and internships interchangeably, so it’s important to understand the type of fieldwork you could be required to complete. A practicum is typically designed to provide supervised, practical work experience in a specialized field of study. An internship may require you to perform duties similar to those of a future position, sometimes with a stipend for your services.

International Practicums

Some schools offer the opportunity to pursue a practicum overseas. For instance, you could put your knowledge of public health to the test in a European country and learn how other cultures approach the public good.

Alternately, you might study the impact of the environment on health in a Third World nation. If you want to study abroad to see different approaches to healthcare, pursue a program that offers this as an option. Even if your school does not have such a program, you might be able to participate in another school’s international program and transfer the credit back to your alma mater.

Always seek out solutions that will work best for you and your goals. Your advisor is sure to support you in finding the options that suit you best.


Accreditation is the seal of approval issued by peers within the educational system and industry who frequently examine schools and their coursework to ensure they meet industry standards and prepare you to perform at the highest level.

Benefits include:

  • Employers may require job candidates to be graduates of accredited schools.
  • You likely will not be able to transfer credits from an unaccredited program to an accredited program if you decide to change schools.

Make sure your school and program are accredited by a regional or professional commission or agency so you’re sure you’ve graduated from a quality program.
