The culture of visiting days is common in Kenyan boarding schools yet there is no universal policy to regulate this occasion. Each school has independent internal policies on when to visit, who visits, and what the visitors bring to students on visiting days. These policies are often flouted resulting into indiscipline. The purpose of this study was to investigate the implications of management of visiting days on students' discipline in Lugari District of Western Province Kenya. Ten schools were sampled comprising of three boys boarding, four girls boarding, seven mixed day and boarding while three were girls' day and boarding schools. The sample size was 1,303 students, ten principals, ten teachers in charge of boarding and ten school workers. Data were collected using questionnaires, interview and observation schedules and document analysis. Analysis was done using descriptive statistics and data were presented on tables, pie charts and bar graphs. The population of the study comprised of all the 42 secondary schools comprising of 13,236 students. Schools were categorized into five types: pure boys' boarding, pure girls' boarding, pure girls' day and boarding, mixed day and boarding and day schools. The study revealed that all the sampled schools had varied internal policies regulating visiting days and the same were not universally enforced paving way to indiscipline among students in boarding secondary schools. In an attempt to minimize negative external influence on students, the study recommends that the Ministry of Education should formulate policies to guide these occasions. The policies should stipulate the level of involvement of parents in their children's education as well as create awareness to school managers with regard to discipline in boarding secondary schools.
