This study aimed at finding the Impact of Concept Attainment Model on Achievement, Stress and Attitude towards Mathematics of 10^th Grade students. A sample of 100 Students of 10^th Grade was selected randomly from Inchageri Village of Indi Taluka of Vijayapur District. Among them 50 Students were randomly selected for each controlled and Experimental group. In this study experimental-control (pre-test post-test) parallel group design was used.  The study was completed in two stages: Pre-test stage and Post-test stage. The data were collected and analyzed with the help of Differential analyses i.e.  T-test. A significant difference was found between the Pre-Test and Post-Test scores of Achievement, Stress, and Attitude towards Mathematics of both experimental and controlled group. The study reveals that the gain of achievement and Attitude towards Mathematics of experimental group is higher than the control group and the gain of Stress in Mathematics of experimental group is lower than the control group. It shows that the treatment given to experimental group through Concept Attainment Model is more effective than the Traditional method of teaching.

KEY WORDS: Concept Attainment Model, Achievement, Stress, Attitude towards Mathematics.
