Procrastination is a complex phenomenon referred towards the postponement of a planned task that can also be defined as an illogical and irrational delay. The study was an attempt to find out the relationship between the phenomenon of academic procrastination and students achievement at university level. The objectives of the study were to identify the tasks in which students procrastinate the most with an exploration of the causes for academic procrastination. Furthermore, the relationship between academic procrastination and students’ achievement was explored. Students’ interest in changing their attitude of academic procrastination was also assessed. The study was a co-relational study. The relationship between academic procrastination and students’ achievement was explored. In typological context, five public sector universities were randomly selected out of 20 public sector universities in Punjab. Multi-stage cluster sampling technique was used and the total 365 M.Phil level students (All students studying in the sampled departments) and twenty five university teachers, teaching at M.Phil level (one teacher from each sampled department) formed sample of the study. Procrastination Assessment Scale for Students (PASS) was adopted to collect quantitative data from the students and semi-structure interviews of the teachers were conducted for qualitative section. Data were collected through mail and personal visits and analyzed by using SPSS. Both descriptive and inferential statistics were used. Major findings and conclusions of the study revealed that majority of the students at university level are the high procrastinators in all the six identified academic tasks. The main causes for academic procrastination were dependency and help seeking, risk-taking, socialization, pleasant verses boring tasks, fail to prioritize, lack of focus, socialization, poor time management, no check and balance from parents, leniency of the teachers, not clear goals, carelessness, and lack of motivation.
