Learner satisfaction is a crucial element to quality learning and has an influence on academic performance. This study aimed to assess the level of learner satisfaction with teaching and learning and determine its influence on academic achievement in public secondary schools in Kisumu East Sub- County, Kenya. A mix of stratified random sampling was used to determine 303 respondents. There was a total of 128 (42.29 %) males and 175 (57.71 %) females. Majority of the respondents were aged 18 years 87 (28.72%) with 78 learners (25.71%) having a mean grade of C+. Learners reported the highest satisfaction with the manner in which the teachers encouraged interaction among learners which enhanced learning. Learners were least satisfied with the equipment of library. Overall learner satisfaction was 4.08 (1.147), showing learners were generally satisfied with teaching and learning. There was a significant positive correlation r= 0.238 (_p=0.002_) between learner satisfaction and academic achievement. Further studies should be done to identify other aspects that influence learner satisfaction. The relevant stakeholders should provide schools with the necessary facilities to ensure quality education.
