Further evidences on the efficacy of treatments based on the automatisation of sub-lexical recognition are presented. With five independent samples, after an average of three months of intervention, the increment of reading fluency has been similar or superior to that expected after one year without specific treatments even if wide individual differences are observed. Of particular interest are the outcome observed after two and three cycles of treatment with two further independent samples. The main results are that reading fluency improve at almost the same amount after each cycle allowing some participant to improve their reading fluency at a level sufficient to read and study a text independently. The efficacy of treatments aimed at improving the automatisation of syllables presenting text by special software, receive a further support even if much remain to study about the causes of the wide individual differences to treatments.
