Hi Emily. In my opinion, no mater if you’re training an individual or a small group, there are certain “minimum” assessment tools that everyone should use. For example, a PAR-Q, and a health assessment questionnaire would be this bare minimum for me. However, when I’m working with a group, I will also include other assessments that I feel are pertinent to the group or the type of training that they will be undergoing. For example, with a group of seniors, I may require each senior to obtain a physician’s approval.
I hope that this helps.
