“…Attempts to develop reliable and valid instruments and processes in social work and in other professions have been hampered by the lack of standardized definitions of competency and the lack of agreed upon performance indicators (Bondy, et al, 1997;Sliwa & Kowalske, 2000;Siegel & Greenberg, 2000).
