Financial resources allocated to guidance and counseling services help school counselors to design, deliver and manage inclusive school counseling programs that are meant to promote student achievement. The counseling program is meant to focus on academic, career, and social/emotional curriculum that is delivered through classroom lessons, small groups, and individual consultation. Despite such programs, various research studies have indicated cases of student unrest and poor performance in most schools in Kenya in the recent past. Evidence from studies worldwide shows that many students have emotional and behavioral problems which cause frustrations and despair. Guidance and counseling is a powerful means of giving students support and help with individual problems. The purpose of the study was therefore to establish the effect of Guidance and Counseling Services financial resource management on students’ academic performance in Kenya using Kisii County as the site of the study. Based on the findings of the study it was established that there was a statistically significant relationship between the principals’ provision of Guidance and Counseling financial resources to students’ academic performance. The actual effect was that financial management of resources allocated to Guidance and Counseling services accounted for 66.7% of students’ academic performance. The study recommend that funds allocated to Guidance and Counseling resource management be prudently used.
