As the science community has recognized the vital role of communicating to the public, science communication training has proliferated. The development of rigorous, comparable approaches to assessment of training has not kept pace. We conducted a fully controlled experiment using a semester-long science communication course, and audience assessment of communicator performance. Evaluators scored the communication competence of trainees and their matched, untrained controls, before and after training. Bayesian analysis of the data showed very small gains in communication skills of trainees, and no difference from untrained controls. High variance in scores suggests little agreement on what constitutes “good” communication.
