Frequently Asked Questions

What is the Diploma in Performance Nutrition?

Our Diploma in Performance Nutrition is an internationally recognised post graduate level professional program for current and aspiring performance nutritionists with a focus on applying the science to real-world practice.

Do you still offer the ISSN Diploma course?

The ISSN Diploma, originally conceived and developed by Dr Laurent Bannock, was our flagship program for the past 5 years. In that time we, as a professional education institute, have evolved significantly, and so has the body of knowledge in sport and exercise nutrition. Dr Bannock’s recent doctoral research, in bridging the gap between science and practice in sport and exercise nutrition, resulted in the creation of our new flagship program, the ‘Diploma in Performance Nutrition’, which officially launches with the inaugural February 2019 cohort.

To reflect the significant changes in the program, we decided to change the name. All new applications for our diploma program will now be for the Diploma in Performance Nutrition.

All current ISSN Diploma students (i.e. the 2018 cohorts) who successfully complete the program will still graduate in 2019 with the ISSN Diploma (or can transfer to the new Diploma, please contact us for more information).

Our Diploma in Performance Nutrition students will still have the opportunity, and are encouraged, to sit for the CISSN ‘Certified sports Nutritionist’ examination, which will make for a valuable additional credential in the graduates’ professional portfolio. It is, however, now optional and no longer a graduation requirement of our program.

How much time will the course take to complete?

The Diploma in Performance Nutrition is part-time and has been designed to be flexible enough to accommodate students in full-time work or with other commitments.

The average student will take 12 months to complete the program, with some taking as little as 8 months with greater time invested.

Do I need existing qualifications to be eligible to apply?

Yes, it is an advanced level program and will require an appropriate amount of prior knowledge to build upon.

You EITHER need to have a relevant university degree (i.e. sport science, nutrition, dietetics etc);

OR accredited professional certifications (i.e. personal training, nutrition coaching etc) PLUS a minimum of 1 year of relevant experience (i.e. as a personal trainer, S&C coach, or nutritionist). This is a postgraduate level course and this requires relevant underpinning knowledge such as exercise science and basic nutrition from evidence-based sources.

Is this an Attendance (in UK) or Online / Distance Learning Course?

The Diploma in Performance Nutrition has been designed to be undertaken online using our special online learning environment with downloadable lecture videos, electronic format reading materials and online interactions with fellow students and tutors.


Students (and graduates) are also encouraged to attend our live events in the UK, at a special discounted rate. These events are not mandatory to graduate from the program.

What qualification(s) will I get?

Upon successful completion of all course requirements, you will earn the Guru Performance Institute’s post graduate level ‘Diploma in Performance Nutrition’. Graduates will also be provided with an official transcript of studies.

The program also promotes a number of optional professional certifications to include UKAD Anti Doping Advisor (free), ISAK Level 1 Anthropometrist (at additional cost), and CISSN ‘Certified Sports Nutritionist’ certification (at additional cost).

UK graduates will also be encouraged to apply for professional registration (at additional cost) with the British Dietetic Association’s UK Sport and Exercise Nutrition Register (SENr), and/or with the the Association for Nutrition’s UK Voluntary Register of Nutritionists (UKVRN) for which our program can help support portfolio applications (beyond additional suitable credentials such as a BSc or MSc in Nutrition, Dietetics, Sport Science etc).


Will it be internationally recognised?

Yes, it is internationally recognised and accredited by many leading professional bodies and academic institutions in related fields (with more UK and international accreditations currently being sought).
