This study, Perceptions of Stakeholders on Prevailing Organizational Climates in Colleges of Education in North-West Zone of Nigeria? addressed seven objectives, among which were to: examine the perceptions of lecturers, non-academic and management staff on the prevailing open organizational climate and ascertain the perceptions of lecturers, non-academic and management staff on the prevailing closed organizational climate in Colleges of Education in North-West Zone of Nigeria. Also, seven research questions were asked and seven null hypotheses formulated for the study. Two of the hypotheses stated that there are no significant differences in the perceptions of stakeholders on the prevailing autonomous organizational climate and the perceived organizational climate by stakeholders between state and federal Colleges of Education in North-West Zone of Nigeria. Survey research design was used to describe the phenomenon in the natural setting. Five Colleges of Education were selected by use of stratified random sampling to cover both state and federal colleges. The total population of subjects studied was 2,420 while the sampled respondents in the study were 393, made up of 333 lecturers, 40 non-academic staff and 20 management staff. Data were collected by use of structured questionnaire. The questionnaire contained 60 items. Measuring instrument used was 5-point Likert ranking scale. The statistical tools employed for the analysis of data were percentages and frequency counts, Mean, Analysis of Variance (ANOVA) and t-test at a significant level of 0.05. All the 7 null hypotheses tested were rejected as P-value was less than 0.05; which means that there was significant difference in the perceptions of stakeholders (lecturers, management and non-academic staff) on the prevailing organizational climates in Colleges of Education in North-West Zone of Nigeria. Despite the disparity in respondents? perceptions, the findings revealed that the most prevailing organizational climates in the Colleges were open and autonomous climates (in which management behaviours showed more of positive characteristics in such areas like cordial relations, satisfactory disciplinary measures, feeling of general good fellowship and helpfulness among members, freedom to carry out duty, appropriate work schedule). Similarly, climates such as controlled, familiar, paternal and closed were perceived differently by the stakeholders. This led to further analysis, where Post hoc test using Scheffe?s Multiple test to ascertain the extent of the differences were used. Then, based on the Scheffe?s test, lecturers? and non-academic staff opinions still revealed no significant difference; but the opinion of the two simultaneously differs from that of the management. The study concluded that the six organizational climates were found to be prevailing in the colleges; at least in parts, but the predominant ones were open and autonomous climates. Hence, the study recommended among others that open and autonomous climates should be maintained and improved upon by the college-based stakeholders as there is still room for improvement based on lecturers? perceptions. Thus, managers should encourage participatory approach to decision making for enhanced work relationships and creativity; ensure prompt rewards and appropriate communication system that would be bi-directional and lateral, provide feedback corrective measures to employees, employ modern techniques in motivating workers
