This study was developed with the aim of providing empirical evidence for the structuring of language skills by learning expected in the sixth grade, in the wake of widespread educational reform of the elementary schools in Mexico. For this purpose it was built and subjected to construct validation an assessment instrument in sixth grade in two contests: 1. Reading comprehension and 2. Production of own texts, which, after validation by judges, was administered to 87 sixth grade students of public schools in the municipality of Cuautla, Morelos. In spite of some inconsistencies in the specification of learning expected in the SEP’ program and some activities in the textbook, the structural models with confirmatory analysis, supported the structuring of learning communication competences and the expected learning these skills inherent, in reading comprehension and production of texts.
