In this work, we perform a comparative study about the treatment of compound proportionality in 6 series of Secondary Spanish textbooks (age 12-16). These series belong to two different publishing houses and were published under the last three educative periods implemented in Spain. This is an a priori textual analysis carried out under the paradigm of content analysis and structured through different categories. Among other results, we conclude that there is great variability on the treatment given to compound proportionality although the types of problems and their contexts are very homogeneous. In addition, we detect deficiencies, among other aspects, in the characterizations and justifications used in the texts.
