All belonged to the Christian Endeavor Society and conducted services each Sunday and sometimes on weekdays in the neighborhood villages. Between 1905 and now, the school have witnessed development in all aspects of life. At commencement, the curriculum comprised elementary school subjects, teaching methods and preaching. At some point, the syllabus was revised to include lessons in printing, bookbinding, carpentry, and elementary sciences. In 1955, the school had on roll 170 boys and 12 teachers. While the school has been an all-boys school from inception, girls were later admitted to be part of the two-year Higher Certificate (Arts) classes (Forms 6 and 7). Higher School Certificate (Science) course was later added in January 1963. By February 1977 according to the school records, enrolment was 888 (718 boarders, 170 day students). Among the boarders there were 17 girls, all belonging to the Higher School Certificate (Arts) Course. Tremendous growth was also witnessed in all spheres of sports activities with the introduction of new games like cricket, quoits, inter-class/inter-school football matches, etc. A report in 1962 had it that, the athletics team consistently gave a good account of themselves in the Provincial A.A.A. and Wilson PARNABY sport meetings. As at 1980 the students population grew to 1099 with 30 teachers. Joint inter-house sports competition and Sunday service with the sister school, Mary Hanney Secondary School had since assumed a regular feature. School Uniform One of the distinctive marks of MBHS Oron students is their uniform – Initially, a jacket with a pocket batch and the Institute's cap were used. Later years saw alteration in the following uniform combinations which has remained signature colors for the school; white shirt on either of brown khaki shorts/trousers, white shorts/trousers, or maroon shorts/trousers for junior and senior students respectively. These are complemented with a maroon blazer or half jacket (with a pocket batch) especially during ceremonial outings. The later is also adopted by the Alumni as their dress code during official functions. For evening wears, orange shirt on grey coloured shorts/trousers are worn, while white shirt (preferably long sleeves) on white trousers are also used during Sunday Services. In all of these, girls in the Higher School Certificate Classes wore skirts in place of shorts or trousers.
