The present systematic literature review contributes to this need by summarizing available findings on evidence-based literacy interventions (EBI) for children from first to third year of primary school. Our results are based on 20 EBI that aimed at improving at least one of the critical components mentioned by the NRP (2000): phonological awareness, phonics, fluency, vocabulary and comprehension. As 90\% of the studies were completed with English-speaking children, we critically discussed the applicability of this evidence to the specific context of Spanish-speaking countries. Although many of the general characteristics of the EBI completed with English speaking children could also guide interventions in Spanish, it remains crucial to take into account structural differences between the orthographies of both languages. Moreover, we identified transversal strategies and implementation techniques that due to their universal character could also be useful for early literacy interventions in Spanish.

Possible explanations are partly based on the incidence of orthography-specific factors influencing the reading process, but also on methodological differences that hinder comparison of the reported results. For this reason, the present study aims to analyse the prevalence of RD in a sample of 1,408 Spanish-speaking school children by comparing different ways of calculating the prevalence rate. The results reflect a prevalence of 2.2-5.3\%, consistent with data reported for predominantly transparent orthographies. Some of the procedures used to identify RD are more accurate in early school years than at more advanced moments of schooling. Furthermore, the consideration of students' sex when calculating the prevalence of RD seems to represent a more sensitive way of identifying students with RD.}, language = {es} }
