Clinical supervision in the 21st century: revisiting pressing needs and impressing possibilities.

What are some of the most pressing needs currently confronting clinical supervision? In this paper, I give attention to that question. Drawing on two 1990 reviews for comparative purposes, I examine where supervision is now relative to four areas: (a) supervision training and practice; (b) measurement; (c) difference and diversity; and (d) research. Lines of advance, pressing needs, and potential remedies are considered across each area. Effort is made to accentuate the "robustly international" nature of clinical supervision and its increasing globalization.
