Varicose veins are enlarged, twisted veins commonly found in the legs due to high pressure   from standing. They occur when vein valves fail to prevent blood from flowing backwards.  This study aimed to evaluate a teaching program designed to improve teachers' knowledge on preventing varicose veins. Using a pre-experimental design, 40 teachers were selected through
non-probability purposive sampling and assessed with a self-structured questionnaire before  and after the program. Initial results showed a mean knowledge score of 9.1 (SD 3.65), which   improved to 3.66 (SD 2.73) post-teaching. The t-value was 7.56, indicating significant improvement  (p<0.05). Initially, 45% of teachers had inadequate knowledge, 52.5% had moderate knowledge,
and 2.5% had adequate knowledge. Post-program, only 2.5% had inadequate knowledge, 7.5% had  moderate knowledge, and 90% had adequate knowledge. The study concluded that the teaching program effectively enhanced teachers' knowledge on preventing varicose veins.
