This paper aimed to bring to light the consequences of parents’ negligence on students of boarding schools which do not promote the proper practice of in-loco-parentis. Conceptual methodology was adopted to examine relevant concepts to the study. Observation on the impetus of the study was made in model boarding schools in Lagos State. In furtherance, the roles of boarding school teachers and the parents of the boarding school students regarding in-loco parentis were examined in addition to the challenges that abound on the subject matter. Though in-loco parentis allows teachers to perform some responsibilities of parents in discharging their duties over their students, the study concluded that the roles of parents of students in boarding schools should not be put on hold because the students are not under the care of their parents for some periods, parents are first teacher, mentor, and guidance to their children. There are limits to what teachers in boarding schools can do on in-loco parentis. Based on the conclusions, it was recommended among others that parents should ensure that their children are well-nurtured, trained, and of good conduct before sending them to a boarding school.
