The study made efforts to critically investigate and analyze appraisal as a determinant for adequate compensation in private sector organizations in Nigeria. Six major private sector organizations in Nigeria’s manufacturing and service industries, listed on the Nigeria stock exchange were served with structured questionnaire to elicit information needed to test the research hypotheses.
