This paper presents a description of a framework developed to carry out the analysis of the justifications of theorems that appear in textbooks. This framework brings together the concepts of proof scheme, preformal proof, functions of proofs and other more general aspects of proof. The justifications of the Rolle’s Theorem and the mean value theorem in six textbooks were examined using this framework. Each of these six textbooks corresponds to one of the last three Spanish Education Laws: two to the 70’s Act, two to the 90’s Act and two to the Act of 2006. Results, framework’s applicability and usefulness, conclusions and open problems are presented in a discursive way
