The study aimed at investigating the availability and accessibility of teaching materials in the preparedness of the teachers in the implementation of the Lower Secondary Curriculum in Government Aided schools in Mbarara City South, Uganda. Methodology This study employed a descriptive survey research design, targeting participants including city inspectors of schools, teachers, headteachers, and directors of studies, with a sample size of 199. Data was collected using questionnaires and interview guides, analyzed using SPSS for descriptive statistics, and presented thematically. Results 199 respondents participated in this study, among teachers, 65 (53.7%) were male, while 56 (46.3%) were female, majority of headteachers (n = 4, 66.7%) and directors of studies (n = 4, 66.7%) were male, with only 2 females (33.3%) in each of these roles. The findings reported the availability of teaching materials in implementing the Lower Secondary Curriculum in government-aided schools in Mbarara City South (mean score = 3.90), majority of respondents agreed with the statement that teaching materials are sufficient for every learner, where 44 (36.4%) strongly agreed, 43 (35.5%) agreed, and 3 (2.5%) did not give a response. More than half of the respondents, 62 (51.2%), agreed that the computer laboratory was well equipped, while 27 (22.3%) strongly agreed. However, 19 (15.7%) remained undecided, and only 13 (10.8%) disagreed. Qualitative insights reported the need for increased government funding, retooling of teachers, and infrastructural improvements.
