The results of the study revealed that both federal and state public Colleges of Education in Kano State complied with approved guidelines on staff recruitment; that public Colleges of Education in Kano State were designed into a structure of schools, departments and units as well as functional positions and offices; that job behavior required in terms of roles, duties, and responsibilities of functional positions and offices were clearly described and that the associated standard features of job specification in the Colleges of Education in Kano State were apparently employed in the process of recruitment or assigning of official positions to staff. Also training and development programmes in Colleges of Education in Kano State enhanced staff productivity and effectiveness due to active participation in national and international seminars, workshops, conferences and self-development efforts through readings of current and related articles in journals and other sources.
