Accreditation / Recognition

IOPN Accreditations

The IOPN Diploma is an advanced (Level 7) competency-based professional education program. Many of our students undertake the IOPN Diploma to bridge the gap between their university studies and “real world” practice and/or to enable access to post-graduate study in those that did not attend university but are eligible to apply for the IOPN Diploma having earned extensive relevant professional certifications and experience in fitness and nutrition.

Most of our students who have a relevant degree (i.e. sport science, dietetics etc) undertake the IOPN Diploma to enhance their credentials in order to increase their employability and most importantly their confidence and competence to practice in both professional team settings and in private practice as a consultant.

Masters Degree Access:

The IOPN Diploma in Performance Nutrition is an advanced (level 6 and 7 in the UK education framework) professional training and development program that has also been designed to support professional registration competencies for a number of professional bodies (currently SENr and AfN) in their requirements to support a portfolio application for sport and exercise nutritionist registration in those that are eligible to apply.

Due to the level and comprehensiveness of our program many universities will consider an application from an IOPN graduate for entry onto their MSc degree program. Please note that if you already have an MSc in a related area, such as Sport Science, Exercise Physiology, Nutrition, Dietetics, or Strength and Conditioning, then the successful completion of the IOPN Diploma in Performance Nutrition will already enable you to apply for professional graduate registration with the UK Sport and Exercise Nutrition Register (see our Pathways to SENr PDF download).
