The school uniform is the pride of every learner and must always be clean and clearly marked. Students are requested to wear the school uniform daily. Shorts, Bermudas, jeans, and short skirts are not allowed. Students are also required to wear reasonable footwear. No sandals, crocs, or slippers are permitted; students must always wear closed shoes (black or navy blue) with white socks. The sports uniform should be worn during the P.E. sessions, and students should come to school wearing that uniform. P.E. Uniforms and the school’s official uniforms are available at the school uniform shop. Thamer International Schools believe that uniforms are an integral part of operating a safe and effective school environment. Therefore, all students are required to wear the school uniform unless the school authorizes special “nonuniform” days.

Personal hygiene is the most important thing. Hair must be clean and neat. Girls’ hair must be tied at all times. Boys' hair should be short and neat. Long hairstyles are strictly forbidden for boys. Unusual hairstyles are not permitted at an educational institution. Learners will immediately be sent home and may only return to school once their hair conforms to the school’s policy. No make-up is allowed, and nail varnish is prohibited. Nails need to be cut and kept clean constantly.
No valuable items (expensive watches, necklaces, rings, etc.) should be worn in school. Students should leave their valuables at home; these include iPods, iPads, mp3s, electronic games, smart watches, large sums of money, etc. Regarding jewellery, girls may only wear one stud per ear, and boys are not permitted to wear earrings at all. Both boys and girls may wear a wristwatch. No necklaces, anklets, or bracelets are allowed to be worn by students. No facial jewellery is worn, other than the aforementioned ear stud. Mobile phones are strictly forbidden for Primary School students. For middle / senior schools, mobiles are to be turned off and collected by the floor supervisors early in the morning and will be given back only at dismissal time. Violations of this rule will result in confiscating the mobile. In case of an emergency, students may call their parents from the administration. Generally, forgotten homework, books, etc., are not considered an emergency. The school is not responsible for any lost valuable items mentioned or not mentioned above.
