The learning environment has a strong impact on students' learning experiences and outcomes; it dictates what, how, when and why students will learn. Also, it affects students' level of enthusiasm, encouragement and degree of learning effectiveness. A non experimental, descriptive research design was used to assess the perception regarding class room learning environment among undergraduate nursing students. DREEM (Dundee Ready Educational Environment Measure) by Mcleer and Roff was used to determine class room learning environment. Five Nursing institutions were selected conveniently to select 500 randomly selected students. The findings of the study revealed that majority (81.2%) of the study subjects were having good perception of their class room learning environment followed by 16.2% with very good perception score. Only 2% of them were having average perception whereas none of them were having poor perception of their class room learning environment. Perceived classroom learning environment score was found out to be significant with the mother's occupation at 0.01 level of significance and gender and type of family at 0.05 level of significance respectively.
