There is a close connection between reading and writing. Several studies suggest integrating reading in the instruction of teaching writing skills to English as a Foreign Language (EFL) learner. This study seeks to determine the extent Saudi EFL teachers support, apply and understand the theory of integration between reading and writing. To achieve the research objectives, the researcher compiled two lesson plans; one based on the integration theory and the other, based on a traditional model to see which lesson plan teacher-participants chose to teach writing. The data was then collected through questionnaire containing both closed and open-ended questions to determine the implications of the results in relation to the objectives of the research. The major findings of this research project were that, for the ten EFL teachers surveyed, most of the teachers indicated that they usually taught writing as a separate skill apart from reading, and the written responses from the open-ended questions that was analyzed indicated that the teachers taught writing in the traditional way. The results from the ten participants' responses also suggested that almost none of the participants were familiar with the concept of integrating reading and writing for the purposes of teaching writing. However, most of the respondents did comment that they agree with the idea of integrating reading in the instruction of teaching the writing skills and given a choice of a lesson plan, most of the teachers choose the integrated lesson plan.
