Academic achievement is the outcome of education — the extent to which a student has achieved his/her educational goals. It is the ability to attain success in one’s studies; is commonly measured by examinations. This focus on academic achievement comes to fore in the adolescent phase of a student’s life, especially as they approach the tenth boards. Parents and teachers dramatically increase the attention paid to academic achievement in this phase. It becomes the central issue of concern and discussion in most families.
