The children of navvies were subject to the vagaries of an itinerant lifestyle, and during the latter years of the nineteenth century this invariably affected their relationship with an educational system that mandated compulsory attendance. Based primarily on school records, this article explores the contrasting ways in which teachers perceived navvy children who were admitted to a number of schools during the construction of one particular railway in the mid-1890s. Perceptions concerning the children's behaviour, attendance, abilities and educational progress, together with evidence of the treatment they received, are considered in the context of contemporary attitudes towards the navvy community and aspects of the navvy lifestyle. The admission of navvy children also had logistical implications for schools, and these are assessed in terms of the pressures placed upon financial resources and teaching staff. This illustrates the disparity that could exist between small rural schools and larger schools in urban areas.
