Feedback is proposed to be a critical element of formative assessment (FA) but evidence reflects its sparse and incongruous implementation . Current study on feedback sessions post formative assessment was undertaken to establish the extent to which it can make significant contribution in improving learning outcomes. An Experimental, Randomized, Controlled study with sample population being 1st MBBS – 2011 students , were randomized into cases (n= 37) and matched controls ( n= 38) . The cases underwent feedback sessions after FA. Difference in scores between cases and controls in Summative (SA) was statistically significant (p< 0.002). Scores in FA and SA was statistically non-significant (p = 0.30) within controls (n=37) and statistically significant (p= 0.006) within cases ( n= 38). Qualitative analysis was done for comparing the utility and efficacy of written comments on answer sheets compared to feedback sessions. Study concludes that feedback sessions post - FA, irrespective of success, may determine greater involvement of students in learning process and improve learning outcome.
