This work was intended to access teachers’ perceptions and statistical knowledge for teaching statistics using modeling in secondary schools. The data were collected from secondary school mathematics teachers in Addis Ababa, Ethiopia. Questionnaire and interview were instruments employed for data collection. Thus the findings indicated that most respondents have positive perceptions for teaching statistics topics. Other main finding was teachers statistical knowledge, the results indicated that minority of teachers haven’t necessary statistical knowledge for teaching statistical topics. Because in my country Ethiopia mathematics teachers’ were trained to teach mathematics rather than statistics and they were took sometimes one introductory statistic course. But in secondary schools mathematics book, there are some statistical topics to be taught. It was also found that teachers didn’t use modeling when they teach those topics because of different challenges like; teacher’s knowledge, time, motivation, facilities, and students’ background knowledge.
