There is a growing interest among the higher education principals and policy makers to improve teacher evaluation methods and more important than that to use the evaluation data. A number of research studies implied the ineffective instruction of ESP courses in Iran (Atai, 2002; Eslami, 2005; Hayati, 2008; Ahmadi, 2008; Sherkatolabbasi & Mahdavi, 2012; Boniadi, Ghojazadeh & Rahmatvand, 2013). The basic objective of research in field of ESP/EGP instruction and evaluation is to facilitate informed decisions for the betterment of English classes. The literature suggested that most of the teachers and students were dissatisfied with the students’ progress in specific English courses. Data was collected from the teachers by various ways including observation checklist and feedback form. To carry out the study, 12 ESP and EGP teachers were observed using Marshall’s rubrics (2011) and observation logs’ analysis. Then, 18 teachers offered feedback on different aspects of their own courses. The data were analyzed both qualitatively and quantitatively using ANOVA statistical measurement. The findings firstly indicate that EGP teachers were more standard teachers in comparison to ESP teachers. Secondly, the feedback forms show discrepancy between the views of EGP teachers and ESP teachers in some areas including the material effectiveness and students’ interest. To reach a standard point in EGP/ESP instruction, more evaluation is to be applied by the faculty members, university principals and the teachers themselves. Politically correct attitudes towards teachers should not lead to ineffective English courses. Some practical implications are suggested to upgrade the current practice in ESP classes
