The third lesson in Introduction to Translational Science provides an introduction to T2 research, which is research that translates findings from T1 research (humans) to patients. T2 research is often conducted through Phase III clinical trials, observational studies, evidence synthesis, and clinical guidelines development. The fourth lesson in Introduction to Translational Science provides an introduction to T3 research, which is research that translates findings from T2 research (patients) to actual clinical practices. T3 research is often conducted through Phase IV clinical trials, health services research, and clinical outcomes research.

The fifth lesson of Introduction to Translational Science provides an introduction to T4 research, which is research that translates findings from practices (T3 research) to communities, both domestic and globally. T4 research is often conducted through prevention and outcome studies, mass screening studies, and health policy studies.The sixth lesson of Introduction to Translational Science provides an overview of how interested individuals can participate in clinical and translational research; as an independent research, as a clinical research professional, and as a study volunteer. The final segment of the module demonstrates what a typical study volunteer will encounter if they are selected to participate in a clinical trial.
