Background: Learning is a process of interaction between lecturer and students. Learning is influenced by two factors namely, internal factor and external factor. External factor is a factor that comes from many things around the students or something relate with students’ daily activities. There are family, learning environment, lecture and teaching methods. While internal factor is coming from the student itself, there are physiological and psychological. From the learning process, can be seen the success or failure of a learning through an achievement that has been obtained. Objective of the research: Identifying the relationship between the classroom learning environment with academic achievement. Research Method: This research uses a correlation research method with cross sectional design approach. Sampling uses a total sampling technique with 412 nursing students in 2017. This research will use the Dundee Ready Education Environment Measure (DREEM) as an instrument that measured by quantitative data analysis. Results: The study showed that there was no correlation between perceptions of the learning environment and academic of nursing students at Pelita Harapan University. It proved by the results of the calculation of correlation using the rank sprearman formula that obtained P-value (p> 0.05) in the amount of 0.402. Suggestion: For future researchers, suggested to conduct further research which related to other factors that could be influenced student learning achievement.
