'client-directed' originates from the combination of 'client' and 'directed', where 'client' refers to a person or organization using the services of a professional, and 'directed' means guided or managed.

The term 'client-directed' evolved from the concept of 'client-centered' approaches in various professional fields, emphasizing the importance of client autonomy and input.

Initially, it meant 'guided by the client', and this meaning has largely remained the same in modern usage.
