1. A computer implemented method, in a data processing system comprising a processor and a memory comprising instructions which are executed by the processor to cause the processor to implement a reading skill assessment system on a cognitive system, the method comprising:

  • processing a body of text in a learning mode;

    applying one or more text mutators to the body of text to produce a mutated text output based on a plurality of randomization rules, wherein the plurality of randomization rules further comprises;

    keeping a first letter and a last letter of a particular word while jumbling all letters between the first letter and the last letter of the particular word;

    transposing one or more letters of text;

    splitting words; and

    jumbling a spelling of a split word;

    presenting the mutated text output to a reader;

    prompting the reader to provide one or more answers to one or more questions through the cognitive system regarding the mutated text output;

    processing the one or more answers provided by the reader;

    processing one or more metrics collected from the reader, wherein the one or more metrics include biometrics and one or more of mean reading duration per word, reading speed, total reading time, correctness of responses regarding text understanding, time needed to provide responses, word reading level with applied text mutators, and sentence reading level with applied text mutators;

    wherein the biometrics includes one or more of heart rate, hormonal status, stress levels, transpiration, and galvanic skin response;

    calculating a reader skill score for the reader based on the collected metrics, wherein one or more machine learning classification algorithms are applied to learn at least one parameter of a scoring function of the reader skill score;

    mapping the calculated reader skill score against one or more baseline reading skill score levels; and

    suggesting a reading skill level to the reader.
