It is a Cross-sectional study in nature. This study was a primary analysis of 400 children who were in primary school. We carried out frequency tabulation, binary and multivariate logistic regression analyses to achieve the study objective. In the study, 89% of students had good knowledge & 71.6% of students had good practice regarding hand washing. The odds of having good knowledge about hand washing were high among the students who were in grade 5 [AOR=2.85; CI 1.418-5.741] and had received hand washing training [AOR=2.58; CI 1.125-5.932]. The odds of having good practice about hand washing were greater among the students who were in grade 5 [AOR=1.8: CI=1.040-3.115], whose fathers were job holder [AOR=3.20; CI 1.267-8.093], whose mothers completed SSC [AOR=3.80; CI 1.786-8.102], HSC & above [AOR=3.99; CI 1.132-14.085] and received hand washing training [AOR=3.93; CI 1.748-8.872).Though the knowledge about hand washing is quite good, a community-based intervention program needs to be carried out to educate the children about the hand washing practice. http://pubs.sciepub.com/ajphr/8/6/3/ajphr-8-6-3.pdf Knowledge Practice Primary school Bangladesh
