Intention based scoring (IBS) is a scoring system, its goal is to provide a score that more accurately assesses a student’s ability to solve a composition problem, and therefore assess direct effects of the student s programming ability. This process is dubbed “intention based” because, firstly, the programs are inspected by inferring what goals the student is trying to achieve, and secondly, what plan component is being attempted when a program statement is not syntactically correct.



The three steps necessary to perform IBS were introduced by [1]: inspection of an on-line protocol, bug identification, and scoring.



The final goal of this project is to create an automated Intention Based Score for each programming assignment, and use K-Mean Clustering to identify which students belong to which group.
