The purpose of the present study was to assess high school teachers' attention to curriculum materials and student contexts, and identify the factors affecting it. The research method was descriptive and correlational. The sample consisted of all teachers of the first grade high school of Babol selected using a cluster sampling method of 202 participants. To collect the data, Peak questionnaire (2014), which measures the amount of teachers' attention to the curriculum materials and student contexts was used. For data analyses, descriptive statistics and inferential statistics (Pearson Correlation Coefficients and Multiple Linear Regression Analysis in a Stepwise Method) were used. The results indicated that the teachers still paid considerable attention to textbooks and assessments but paid little attention to curriculum guides, teacher guide, students’ needs and local characteristics. Teachers’ positive and negative beliefs about curriculum materials, their knowledge, their collaboration with peer teacher assessments, and gender significantly influenced their attention to curriculum materials. In addition, teachers’ attention to curriculum guides and textbooks, gender, assessments, number of students in your classroom, know about the decentralization and collaboration with peer teachers were significant factors in teachers’ attention to local characteristics and students’ needs. Therefore, it is suggested to encourage teachers to use curricula to provide learning opportunities through collaboration with other teachers.
