Final answer:
The model of supervision that adapts to an individual's progression from beginner to advanced practitioner is known as Developmental models, which aligns with theories of growth and adaptation such as psychological empowerment and selective optimization with compensation.
Step-by-step explanation:
A model of supervision in which supervisory skills are modified as the person serving as supervisor moves from a beginner toward an advanced practitioner would best be called Developmental models. These models recognize that individuals progress through different stages of learning and skill acquisition, and therefore the approach to supervision should evolve correspondingly.
By focusing on the developmental needs of the supervisee, these models align with theories that enact principles of growth and adaptation, such as psychological empowerment theory and the selective optimization with compensation theory by Baltes and Baltes, which emphasizes that development is a continual adjustment between the person and their environment.
