As the trainee life coach, you are responsible for finding the necessary eight volunteer practice clients.
Other than two of these who must be bona fide third parties, your volunteers can be friends, family members, colleagues, other trainees, etc - so it shouldn't be too difficult for you.
To assist trainees, we offer a service through our website where we connect New Insights trainees who are looking for practice clients, with members of the public who are looking for free coaching (you'll see 'Life coaching with trainees' in the 'Free Pubic Resources' section of the menu bar on this website.
