This study investigated the “Effects of the My School Certificate Students in Selected Schools in Bauchi Town”. One hundred and forty (140) students were sampled out of two hundred and forty-four (244) total population of two secondary schools. Seventy (70) students were selected in two (2) classes of the SS2 in Government Secondary School Miri, Bauchi State, and were used for the experiment. Another seventy (70) students were selected in the two (2) classes of the SS2 of GSS Shadawanka Barracks, Bauchi State who were used as the control group. The experimental group was treated with eight (8) types of sentence patterns, while the control group embarked on their normal writing lessons for same eight weeks. Both groups were pre-tested before the treatment on the experimental group. A post-test was administered to the two groups after the treatment. T-test was used to analyze the scores obtained from the tests. The overall results revealed significant difference between the written English mean performance scores of the experimental and control groups after the treatment. The study, therefore, recommended the inclusion of the teaching and learning of different sentence patterns in writing lessons among Senior Secondary School Certificate Students.
