An ITS uses a process called Model Tracing to track the learner's progress through the production rules in the cognitive model. At any point in the problem-solving process the learner may request guidance on what to do next, relative to their current location in the model. In addition, the system recognizes when the learner has deviated from the production rules of the model and provides timely feedback for the learner, resulting in a shorter period of time to reach proficiency with the targeted skills.

Knowledge Tracing tracks the learner's progress from problem to problem and builds a profile of strengths and weaknesses relative to the production rules. The Cognitive Tutoring system developed by John Anderson at Carnegie Mellon University uses knowledge tracing in the form of a 'skillometer'; a visual graph of the learner's success in each of the monitored skills related to solving algebra problems. The system continues to present the learner with problems that allow for weaker skills to be developed through practice.
