This study employed survey design in investigating the awareness of the forms, symptoms, modes of transmission, and control of sexually transmitted disease s(STDs) in Kaduna State, Nigeria. A Sample of 500 SS II students comprising 250 girls and 250 boys was drawn from the population using simple random sampling technique. Data were coolected through the use of structured questionnaire. Statistical mean was used to analyse the data and t-test was used in testing the hypotheses. Major findings show that students know very little about the forms of STDs, the students have moderate knowledge of the signs and symptom of various STDs, their of mode of transmission, and they have poor awareness of the control measures toward STDs, there is however, significant differences exist between the boys and girls awareness of the forms and symptoms of STDs. Hence, School Psychologists and counselors should continuously sensitize the students and organize group guidance programme in the secondary schools on personal health and risky behaviours, and there should be a synergy between public health workers, school administrators and parents in creating awareness among students on the risk factors, symptoms and control of STDs, and voluntary HIV test before marriage.
