INTRODUCTIONThe purpose of water, sanitation and hygiene (WASH) in schools is to improve the health and learning performance of school-aged children by reducing water and sanitation related diseases. 1 Other social benefits that can be derived from adequate hygiene and sanitation are self-worth, convenience, privacy, security for women and girls, as well as an increase in school enrolments for girls. 2 In addition to disease prevention, sanitation and hygiene play a significant role on learning, the wider community and life-long skills settings. 3 The above confirmed by studies that indicated that school children with better knowledge and practices of hand hygiene have fewer sick days and absenteeism and attain higher grades. 4,5 However, United Nations Children's Emergency Fund (UNICEF) found that 298 schools in Namibia do not have sanitation facilities, and 93% (276) of these schools are in the five flood-prone northern regions of Oshikoto, Omusati, Ohangwena, Kavango East and Kavango West, and Zambezi regions. 6 ABSTRACT Background: Water, sanitation and hygiene played a significant role in schools by reducing water and sanitation related diseases; subsequently improving the health and learning performance of school-aged children. However, ppeople's knowledge and attitudes on sanitation and hygiene determine the actual practice towards it. This study aimed at assessing and describing the knowledge, attitudes and practices of primary school learners towards sanitation and hygiene. Methods: A quantitative, descriptive design was used. A questionnaire was used to collect data among 450 learners in 10 selected primary schools in Ohangwena region. The study population was grade five, six and seven primary school learners. A three staged probability sampling method was employed. Statistical analysis was done using the Statistical Package for Social Sciences version 23. Results: The result indicated that younger learners in lower school grades, has poorer knowledge, attitudes and practices towards hygiene and sanitation than older learners irrespective of their gender, school circuits or location. This is a logical conclusion because, as learners become older, they become more aware and take precautions about hygiene and sanitation issues. Conclusions: Younger learners in lower school grades, has poorer knowledge, attitudes and practices towards hygiene and sanitation irrespective of their gender, school circuits or location. The older learners become more aware, and cautious about hygiene and sanitation issues comparing to younger learners. The practice and knowledge of sanitation and hygiene are implicated by the reality of the conditions of the sanitation facilities available to them.
