This places you at the top of the field of aromatherapy, empowering you to achieve new heights with your career in aromatherapy and add new skills to your practice or business!

Affordable Tuition

The Franklin Institute of Wellness provides some of the most affordable college programs in the nation. Billing is flexible and easy to budget. You are billed at the start of each academic quarter for the classes you will take during that quarter. Quarterly tuition is controlled by the number of credits you take each quarter, but total program tuition does not change.

To ensure that you remain unaffected by any tuition increases that may occur while you are a student at the Franklin Institute of Wellness, upon admission, you enter into a program agreement with the school. This program agreement confirms your graduation requirements and tuition totals. This agreement protects you from any tuition increases or program requirement changes that may take place while you are a student at FIW, ensuring that your budget and timeline are unaffected while you earn your diploma. The program agreement is valid as long as you remain a student in good standing at FIW. This is determined by adherence to attendance policies and our code of conduct.

Upon acceptance, there is a $135 registration fee, and upon program completion, there is a $65 graduation fee. Tuition is paid per class and is $255 per 30 contact hour class and $425 per 50 contact hour class. TOTAL TUITION for the Certificate in Aromatherapy, including the registration fee and graduation fee, is $1,305. Tuition is paid in increments with each quarter’s registration.

Example Tuition Schedules:

Registration Fee: $135

Quarter 1 (130 contact hours): $1,105

Graduation Fee: $65

TOTAL: $1,305

Registration Fee: $135

Quarter 1 (50 contact hours): $425

*NOTE: Total course load is determined by your personal preference, your budget, your availability, and the availability of each class. This is a sample of a part time schedule assuming course availability.

Not Included in Tuition

Tuition does not include costs associated with textbooks or supplies for required class projects. You will need to budget additional funds to cover the costs of materials you use to formulate your own essential oil products and to purchase the textbooks required for completion of some courses. The cost for textbooks and fees can vary dramatically depending on your personal selections for your projects and your preferred textbook store. 

Tuition assumes full acceptance into the program, which requires meeting all prerequisites. If you are accepted into the program on conditional status and require one or more classes to meet the pre-requisites, the tuition for those classes will be billed at $255 for a 30 contact hour class and $425 for a 50 contact hour class. Many students require a 30 contact hour research methods class to meet the admissions requirements and may opt to that that during the first quarter of part-time registration.

Essential Oil use is evolving. So should your education.

Gone are the days when an aromatherapist could succeed by sticking with inhalation or low dilutions of topical application. Today’s essential oil enthusiasts are using oils in potent concentrations and ingestion regularly. To stay on the cutting edge of the field, today’s aromatherapists must know how to work with clients who choose to ingest oils or to use them topically in high concentrations.

Whether your expertise in aromatherapy is focused on work individually with clients, developing custom blends, or formulating essential oil based products, knowledge of essential oil research, expertise in ingestion, and a deeper awareness of pathophysiology is necessary to achieve continued success in this rapidly growing field.

A Certificate in Essential Oil Ingestion from the Franklin Institute of Wellness empowers you to take your existing career to the next level by integrating new applications and cutting-edge approaches to essential oil applications. A CertEOIngest could also empower you to expand your current aromatherapy profession into a new niche of the essential oil field by building upon your existing skills and expertise.

Essential Oil Ingestion: What Experts Need to Know

August 28 @ 10:00 am - 11:00 am CDT


This program is only open to certified aromatherapists who have completed a 200+ contact hour educational program that is approved by FIW. Programs that are approved by NAHA or AIA are recommended but not required. If you are unsure of whether your aromatherapy certificate qualifies you for this program, you can learn more about the admissions requirements by registering for an admissions webinar or scheduling an appointment with admissions.

For full acceptance, a postsecondary class in research methods, anatomy and physiology, and chemistry are also required. Aromatherapists who earned certifications without completing classes in those three subjects may be conditionally accepted and will be required to complete those classes at FIW to earn a Certificate in Essential Oil Ingestion. 

All applicants must be 18 years of age or older with a minimum of a high school diploma or the equivalent. Students for whom English is not their first language will also be required to submit an English proficiency test to ensure ability to benefit. All applicants must submit official transcripts (issued directly from your previous college or high school), evidence of completion of a 200+ hour aromatherapy program, 2 letters of recommendation, and an admissions essay.

If you do not yet have an aromatherapy certification, we recommend the Certificate in Aromatherapy program, which provides a comprehensive 330 contact hours of in-depth evidence-based aromatherapy education. 

The Application Process

The Application process includes submission of the required materials, an admissions interview with Dr. Jessie Hawkins, and an orientation workshop, which can be completed online. A complete application includes several parts: the application itself, an admissions essay, two letters of recommendation, high school transcripts (these must) be sent to us directly from your secondary school, and college transcripts if you are applying for transfer credit.

The best way to get started is to begin compiling your admissions materials. Think about who may provide your letters of recommendation and begin requesting that your transcripts are sent to us from your previous schools. Then join us for an Open House, Admissions Webinar, or other event outlined above. Keep in mind that admissions typically takes 2-3 weeks, so if your desired program start date is approaching, you will want to reach out to admissions right away to discuss expedited admissions options.
