The purpose of this study is to determine whether or not teachers' lifelong learning tendencies vary by gender, professional field, educational level of service, professional seniority, and frequency of reading a book, magazine, and newspaper. The study employs a descriptive research model. Its population consists of primary teachers and field teachers working in the central district of Kayseri province, located in the middle part of Turkey, in the 2015-2016 academic year. The study group consists of 380 teachers chosen from this population through stratified sampling. The data were collected through Personal Information Form and Lifelong Learning Tendency Scale developed by Diker-Coskun. The obtained data were analyzed via SPSS 20.00 at 0.05 significance level. The study revealed that the teachers working in the middle part of Turkey have low lifelong learning tendencies. Also, the study determined that the teachers' lifelong learning tendencies significantly vary by gender, professional field, educational level of service, and frequency of reading a book, magazine, and newspaper, but professional seniority is not a factor that leads to a significant difference in lifelong learning tendency.
