This study was designed to determine the effects of extensive reading on senior secondary school student’ achievement on vocabulary development and concord in Toro Local Government Area of Bauchi State. The study adopted quasi-experimental research design which involved experimental group and control group.  86 students were sampled from the population of 4452 SS2 students of the 22 senior secondary school of Toro Local Government Area of Bauchi State. Two research questions and two null hypotheses were formulated and tested at 0.5 level of significance to guide the study.  The instrument used for data collection was Comprehension Achievement Test (CAT) which was adopted from validated Intensive English language textbook for SS2. The reliability was found to be 0.70 using Kuder-Richardson. Mean (x) was used to answer the two research questions while t-test was employed to test the two hypotheses. The study found out that extensive reading is more effective in improving secondary school students’ achievement in vocabulary and it has also revealed that extensive reading has a significant effect in students’ understanding of subject-verb concord. However, the study recommended that government should provide enough teaching material which will enhance effective teaching and learning of the all language skills.
