Samuel Mutweleli 2. Anthony IreriSecondary schools in Kenya have been recording poor grades in national examinations in the last five years (2017-2021). This poor performance is worrying because it limits students from joining higher institutions of learning alongside securing jobs in the competitive market. Research has associated poor academic achievement with contextual and psychological factors. This study intended to examine students' academic optimism, school anxiety, and fear of failure as antecedents of students' academic achievement. The primary objective was to ascertain the existence of a correlation between academic optimism, school anxiety, fear of failure, and academic achievement. The predictive weight of academic achievement was also determined given academic optimism, school anxiety, and fear of failure. Martin Seligman’s theory of optimism, theory Albert Bandura’s social cognitive and Birney and Teevan’s fear of failure theory were used to guide this study. The research used an ex post facto research design, and was conducted in Kitui County, Kenya. This research targeted the entire form three students in government sponsored schools in Kitui County in 2023. The sample consisted of 400 students in form three who were chosen from 10 different schools. The schools and participants were selected through purposive and stratified sampling procedures. Simple random technique was also used. Student’s academic achievement was inferred from their end of term 2, year 2023 examinations scores. Piloting of the study was done using 20 form three students in schools within Kitui County. The study used descriptive and inferential statistical procedures to analyze the data. Specifically, it used Pearson’s Product Moment Correlation Coefficient, Multiple regression and ANOVA. Results from the analysis revealed that student’s academic optimism had a positive significant relationship with academic achievement (r (386) = 0.12, p < 0.05). On the other hand, school anxiety and fear of failure had a significant negative relationship with academic achievement (r (386) = -0.24, p< 0.05); (r (386) = -0.15, p< 0.05) respectively. School anxiety was found to be the best predictor of academic achievement scores followed by academic optimism which had a significant and positive predictive value β = -0.22, t (386) = -3.96, p < .05 and β = 0.13, t (386) = 2.72, p < .05 respectively. Findings on exploratory analysis reported that student’s academic optimism, school anxiety and fear of failure varied by school type. This study may benefit educational policymakers by providing them with insights on developing educational practices that make a school a more pleasant environment for its studentsenThesis
