In your opinion is there a difference between an assessment and an evaulation?

Thanks everyone for your responses.

I posed the question because I read something that I found to be very interesting regarding the definition of evaluation. It reads:

“Evaluation is the process that provides evidence that what is done makes a value-added difference in the service/care provided. Evaluation is defined as a systematic process by which the worth of value of something is judged.”

So in short the two are very different. An assessment can be evaluated or an assessment can give value to a services rendered.

Having said the above, do you think it is necessary for us as fitpros to evaluate the assessments we use with our clients?
