The null hypotheses were tested at the 0.05 level of significance. The reliability of the instrument was established using Cronbach Alpha statistics with a value of 0.83. Based on the analysis, the findings of the study revealed that availability of tools and availability of finances affects the effective implementation of guidance and Counseling services in senior secondary schools in Port Harcourt Metropolis.
