Cosmology education has become an integral part of modern physics courses. Directed by National Curricula, major UK examination boards have developed syllabi that contain explicit statements about the model of the Big Bang and the strong observational evidence that supports it. This work examines the similarities and differences in these specifications and addresses when cosmology could be taught within a physics course, what should be included in this teaching and in what sequence it should be taught at different levels.
