This research project aimed at investigating the effects of bullying to the academic performance of students in public secondary schools in Abogeta ward Meru County. The study was conducted to help those who interact or associate with students who suffer the problem of bullying, which end up affecting their performance academically to be able to solve this problem and prevent it from happening to any other student. A sample of 178 respondents was selected for the study with the sample size of 28 teachers and 150 students. Simple random sampling method was employed. This study used questionnaires as a method of data collection. The various forms of bullying to students include physical bullying, verbal bullying and social bullying. The research seeked to provide insights to teachers, school administrators and students’ leaders on the various ways of bullying of students’ in schools, how it affects their academic performance and how they can put a halt to students being bullied in schools. The researcher focused on three major forms of bullying to investigate the effects bullying has on the academic performance of the students. The three forms of bullying include; physical abuse, verbal abuse and social abuse. Under physical abuse, the researcher focused on physical violence, damaging of belongings and sexual harassment, which are the major forms of physical abuse. The study indicated that the highest percentage of students who suffered physical abuse underwent physical violence, whereby the victims suffered injuries, burns and fractures. This affected the academic performance of students in that the students who suffered physical abuse had to skip classes and school to go and seek medical attention. As a result of them skipping the classes, they ended up missing a lot of classroom content and ended up performing poorly academically. Under verbal abuse, the researcher focused on name calling and body shaming. In this form of abuse, the victims ended up being affected psychologically and mentally whereby their self esteem and confidence ended up being lowered and they lost focus in their studies and later ended up performing poorly academically. Under social abuse, the researcher focused on exclusion from social groups and the use of threatening gestures. In the case of exclusion from social groups, the victims were being excluded or denied the freedom of interacting with others. As a result, the students ended up trying to do things that would please the bullies. In that process of trying to please them, they ended up shifting their attention to doing other things and forgetting their books. This therefore leads to them performing poorly academically. Based on the findings and conclusions of the study, the researcher made the following recommendations; clear policies should be established, regular workshops and seminars should be conducted to educate students and staff about bullying, it's impacts and how to prevent it, counselling and support should be provided for victims of bullying. Also, the researcher recommended that a positive school culture should be created by promoting values of kindness, acceptance and cooperation.
